The Sport Bike

 

The Motorcycle Safety Foundation groups motorcycles into the following three separate classes: street, off-road, and dual-sport. A sport bike is a type of motorcycle under the street classification and generally emphasize performance over comfort, passenger/load capacity, and other broad capability.

 

Overview

With the emphasis of a sport bike being on speed, acceleration, deceleration, and maneuverability, there are certain design elements that most motorcycles of this type will share. Sport bikes have comparatively high performance engines resting inside a lightweight frame. The combination of these help maintain structural integrity and chassis rigidity. Braking systems combine higher performance brake pads and multi-piston calipers that clamp onto oversized vented rotors. Suspension systems are advanced in terms of adjustments and materials for increased stability and durability. Front and rear tires are larger and wider than tires found on other types of motorcycles to accommodate higher cornering speeds and greater lean angles. Fairings may or may not be found on a sport bike. When used, the fairings are shaped to reduce aerodynamic drag as much as possible and less as wind protection for the rider. The performance of some stock sport bikes is so great they can be used on a race track right off the showroom floor.

 

These overall design traits mean sport bikes are generally less practical for street use when compared to most other types of motorcycles. There is little in the way of extra features or creature comforts like those present on touring motorcycles such as center stands, provisions for saddle bags, large windshields, or fairings providing protection from rain. Rider position and ergonomics are compromised in favor of weight distribution and aerodynamics. This generally means higher foot pegs that move the legs closer to the body and more of a reach to a lower set of hand controls which positions the body and weight forward and over the tank.

 

The term crotch rocket is slang for some types of sport bikes, mainly super sport and super bikes. The name is derived from the way the rider sits on the bike and from the speed and acceleration of which these bikes are capable. A sport bike's foot pegs and shifter are located farther back than a conventional or 'cruiser' motorcycles; this puts the rider in a position that is more streamlined and aerodynamic and places the rider's crotch in very close contact with the seat.

 

Classes

Although not officially recognized by any major motorcycle organization, the different variations of the sport bike can generally be grouped into several different classes, each containing unique features to that class.

 

Small capacity

Small capacity sport bikes are typically of engine sizes ranging from 125 cc (7.6 cu in) to 400 cc (24.4 cu in), but are also produced in as little as 50 cc (3.1 cu in) (sometimes designed/tuned for persons carrying a restricted/learner's license). Small capacity sport bikes are available in both 2-stroke and 4-stroke cycles. Not as commonly produced now are 2-stroke sports bikes, largely restricted in production due to tight emission laws and agreements. Generally small in size, they can suit the shorter rider and the usual light weight means that although they output less power than larger sports bikes they can perform comparatively similar. Short wheelbase and lack of weight means handling characteristics are often on par with that of the typical high-capacity sport bike.

 

Super sport

Super sport bikes (also known as middleweight sport bikes) are sharply focused for optimal performance on a race track. They are generally built around a high revving, small displacement powerplant that is usually sized around 600 cc (36.6 cu in) to 800 cc (48.8 cu in). Most super sport bikes will carry a wet weight between 375 lb (170 kg) to 450 lb (204 kg) and produce 100 hp (75 kW). Because of how strongly focused super sport bikes are on race track performance, riders with heights of 5 ft 2 in and below will generally find trouble being able to flatfoot (the placement of both feet completely flat on the ground while sitting on a motorcycle) these types of sport bikes. In turn, taller riders and heavier riders may find the rider ergonomics in the default position to be cramped and uncomfortable.

 

Super bike

Super bikes are large displacement super sport bikes. They have characteristics similar to the smaller super sport bikes which are mainly focused on race track performance, but are powered by larger engines that are usually sized around 800 cc (48.8 cu in) to 1100 cc (67.1 cu in). A typical super bike will carry a wet weight between 400 lb (181 kg) to 480 lb (218 kg) and can produce 170 hp (127 kW). Super bikes with a displacement very close to 1000 cc (61 cu in) are sometimes referred to as liter bikes as the engine displaces approximately one liter.

 

Hyper sport

Hyper sport bikes are very large displacement sport bikes with a strong emphasis on top speed and acceleration. They typically are powered by motors displacing 1100 cc (67.1 cu in) to 1400 cc (85.4 cu in). Hyper sport bikes are bigger and heavier than super bikes with wet weights generally being close to 500 lb (227 kg). The increased weight compromises race track capabilities in favor of stability at very high speeds that can exceed 180 mph (290 km/h). This compromise also allows manufacturers to design much more comfortable rider ergonomics.

 

Sport touring

Sport touring bikes are designed with a longer distance riding emphasis. They typically feature more creature comforts than that of the average sport bike. Sport touring bikes are typically heavier, less powerful, and less performance oriented than super sport bikes, but have the added capabilities of storage, more comfortable rider ergonomics, and better practicality. Depending on the amount of emphasis on these touring capabilities, sport touring bikes can range from super sport bikes with more comfortable rider ergonomics to full-featured touring motorcycles with sport bike-like capabilities and features.

Yamaha Motor Co., Ltd. announces the debut of the new “YZF-R15,” a new supersport model mounting a newly designed 150cc liquid-cooled, 4-stroke, SOHC single-cylinder, 4-valve fuel-injected engine on a Deltabox frame.

 

Packed full of state-of-the-art technologies, the new YZF-R15 boasts performance worthy of a supersport model and a body design that evokes the image of the YZF-R series and gives visual expression to the quality of its ride. It is truly an embodiment of Yamaha’s desire to bring customers a model to help them “Enjoy riding”.

 

In Yamaha’s new medium term (3-year) management plan that begins this year and runs through 2010, rebuilding the Yamaha motorcycle business in India has been designated as one of top priorities.

 

The new YZF-R15 now being unveiled is an example of the objective of “introducing attractive new products” called for in Yamaha’s high value-added marketing strategy for India business, and plans call for it to be released on the market in the middle of this year.

 

Market background and product summary

Motorcycle demand in India has grown steadily about 8 million units. This makes it the second largest market in the world. Based on the country’s demographics and progress in development of the road system, it is expected that stable growth will continue from now on. Most of the demand (about 80%) is in the 100cc to 200cc motorcycle category, and a large part of the remainder is in the 125cc and under scooter category.

 

The motorcycle demand in India is driven mainly by young people in their 20s and there is an increasing trend toward European style tastes as seen in the preference for luxury products and stepping up to higher quality goods, which is reflected in growing demand in the trade-in market. Also, among the users in their 20s there is a group that say their dream bike is a 1000cc supersport model, indicating a growing interest in sport bikes.

 

The new YZF-R15 makes full use of the MotoGP race experience and YZF-R series supersport bike development technology and know-how acquired by Yamaha Motor over the years to create a 150cc supersport bike that offers users to truly “Enjoy riding” in a full range of situations, from around-town riding to touring on winding roads and even aggressive riding on the circuit.

 

A development concept was to build “a new 150cc supersport” that is the first model for the Indian market designed in the true supersport image and featuring a high-level balance of enjoyable running performance on winding roads, enjoyable performance and riding comfort with a tandem passenger and agile handling through crowded city traffic. The body has been designed to show at a glance that this is a “R series bike” and to give visual expression to technology feedback from the 10 years of YZF-R series development since the series debut in 1998. In this way, it is a direct expression of Yamaha’s motorcycle development ideal of “Exciting Performance & Stylish Design” in the 150cc class.

 

Main Features

 

A newly developed 150cc liquid-cooled, 4-stroke, SOHC, single-cylinder fuel-injected engine

An all-aluminum “DiASil Cylinder” produced by an exclusive Yamaha casting technology

Eco-friendly performance that clears the next-phase Bharat 4 emissions standard

2008 Yamaha YZF-R125

For 2008 Yamaha will launch the all-new YZF-R125, an exciting new member of the R-series family which is aimed at taking the number one position in the sports 125cc market.

 

Featuring a liquid-cooled single-cylinder engine running in full-sized Deltabox chassis –and clothed in aggressive R-series style bodywork – the YZF-R125 is aimed at the young first-time 125 buyer who demands best-in-class engine and handling performance, and winning R-series style.

 

Engine

 

Yamaha’s first liquid-cooled 125cc 4-stroke 4-valve single

The R125’s all-new 124cc 4-stroke engine is the most advanced in the category, and just like its larger-capacity R-series brothers, it has been developed to deliver class-leading performance.

 

In order to achieve this goal, Yamaha’s engineers have created the company’s first ever liquidcooled 4-stroke single-cylinder 125cc SOHC engine. The new R125 benefits from a 4-valve cylinder head which delivers high levels of intake and exhaust efficiency for ultra-responsive performance.

 

Fuel injection

For instant throttle response, this new high-tech 125 features a compact fuel injection system fed by a large-capacity airbox which, combined with the two inlet valves, delivers optimum intake efficiency together with excellent throttle response across the rev range.

 

Free-revving short-stroke engine

Featuring bore and stroke dimensions of 52mm x 58.6mm, the compact short-stroke engine has a free-revving character which enables it to deliver strong acceleration. This short stroke layout – combined with the performance-boosting qualities of the 4-valve head, fuel injection system and free-flowing exhaust – gives the R125 the strongest overall performance in the 125 4-stroke class.

 

R6-style mid-ship muffler

 

Performance is also enhanced by the fitment of a free-flowing large-capacity R6-style mid-ship muffler, whose location helps to centralise mass for neutral handling performance. The exhaust system accommodates dual catalysers, as well as an air induction system which introduces air into the exhaust to enable more complete combustion of any unburnt gases, and in doing so it helps to reduce emissions to even lower levels.

 

6-speed transmission

To optimise the class-leading performance characteristics of its all-new high-tech 125cc liquid cooled engine, the R125 is equipped with a 6-speed transmission which ensures strong acceleration and a competitive top speed.

Class 2 (>400cc) SportBike

 

 

Yamaha YZF-R6

Yamaha's YZF-R6 is a 600 cc sport bike, first introduced in 1999, updated in 2001, 2003, 2006 and revised in the years in between.

 

===============================================

 

1999 - 2000

In it's debut season, the YZF-R6 was named 1999's "Best 600cc Streetbike" by Cycle World. Sport Rider awarded it "Bike of the Year."

 

In an encore performance, it won Motorcyclists' 600 shoot-out in 2000 and captured Sport Rider's middleweight crown. Almost unheard of in this highly competitive category. The R6 received perfect "10's" for engine power delivery, suspension, brakes and the fun-to-ride category. It received 9's and 9.5's in every other.

 

From the very start the R6 had but one purpose: total domination. Its ultra-compact, ram-air-inducted, short-stroke in-line four makes for one of the most hellacious powerbands in supersport motorcycling. Can you say 15,500 rpm? (14,500 for California models). Its class-shortest wheelbase and featherweight Deltabox II-framed chassis delivers lightning-quick handling and precision that rivals TZ250.

2001

To stay atop the 600 Super Sport class, for 2001 the R6 receives numerous refinements to enhance performance and function.

 

A new, ultra-sleek, R1-like tailsection reduces drag for improved aerodynamics and greater top speed, while a newly designed license plate/rear turn signal bracket provide easy removal for competition.

 

In the engine department, new lightweight forged pistons and carburized connecting rods provide reduced reciprocating mass and superb strength. Revised carburetor settings deliver greater power output from idle all the way up to redline.

Redesigned, lightweight, aluminum clip-on bars provide improved comfort and superior handling.

 

Topping it all off are weight-reducing refinements which shed approximately 5 pounds from this already super light package.

 

For 2001, there's also an R6 Champions Limited Edition model which includes special paint scheme and stamped aluminum authenticity plate signifying the bike's limited production number.

 

The 2001 YZF-R6. The 600 they'll continue to call "Superbike."

2006

In 2006, Yamaha advertised the R6 as capable to running at up to 17,500+ rpm. This is 2000 rpm higher than the previous R6 model and it is the highest redline of a widely distributed production four-stroke engine – the Honda CBR250RR had a reputed redline of 19,000. Such a high speed is near to levels known only in Formula One engines, where valve springs stress problems lead to the adoption of pneumatic return at more than 19,000 rpm.

 

But it was widely reported that the 2006 YZF-R6's motor did not have this redline level and was closer to around 16,200 rpm, because of a tachometer error of about 9%. In February 2006, Yamaha admitted the bike's true redline was more than 1,000 rpm lower than advertised, and offered to buy back any R6 if the customer was unhappy. Even though some riders have reported this to not be a problem and are actually able to rev higher than the 17,500RPM's and well in to the 18,000RPM range.

 

This is not the first time a sportbike's true redline has differed from its redline shown on the tachometer. The 2005 Kawasaki Ninja ZX-6RR has an indicated redline of 16,500 rpm on its tachometer. However, during a SportRider magazine test in the fall of 2005 when testing the ZX-6RR on a dynamometer it wasn't possible to get the motor to rev past 15,000 rpm. The tachometer on most sportbikes is off by a certain percentage. New 600 cc motorcycles are revving up higher and higher, and while the percentage of tachometer error might not change, the error in the number of rpm increases.

1989 Yamaha FZR1000

 

http://pictures.topspeed.com/IMG/crop-380x271/FZR100087_re_3r_bw.jpg

 

The bike that brought Yamaha to the forefront of super bike design was launched in 1987 and it was called FZR1000. The 1987 version of the Yamaha FZR1000 had a top speed of over 250km/h and the 1989 version, crowned “The bike of the Decade”, could accelerate from 0-60 in less than 3 seconds and it also had a top speed of over 270km/h. With these features any bike would be very appreciated, so production continued.

 

Yamaha improved the performance of the bike, notably in 1989 when the engine was enlarged to 1002cc and added an electronically operated exhaust valve whose acronym led to the bike being universally known as the EXUP.

 

In spite of higher displacement its size was 8mm shorter and more compact, due to a revised inclination angle of the cylinders to 35 degrees. Valve angles and sizes had been changed, as well as the camshaft timing. Bigger carburetors helped boost performance and the crankshaft has been strengthened, alog with countless other modifications.

 

The system added useful mid range performance and the engine’s power was also increased to 145bhp.

 

The unique feature which gave the 1989 onward models their “EXUP” name was a servo motor driven exhaust valve. This allowed large bore exhaust reader pipes (for excellent gas flow at high engine speeds) coupled with the valve restricting flow at lower revs, to speed the gas through.

 

The chassis was also improved and the bike handled better, making the EXUP the pick of the Japanese Super bikes.

 

The 1989 frame (now called Delta box 2) used the engine as a stressed member. Gone were the down tubes, replaced by a sturdy fixation of the cylinder head with the frames upper box section. This layout was the foundation for the radical YZF-R1 chassis layout almost 10 years later.

 

But improving didn’t stop there. In 1991 the package was further improved with the FZR1000RU, featuring sharper and upside-down forks.

 

The last model improvements were in 1991 and 1994, until the FZR1000 was replaced by the YZF 1000 Thunder Ace in 1996.

 

==============================================================

 

1995 Yamaha FZR1000

 

http://pictures.topspeed.com/IMG/crop-380x270/FZR100094_bwc1_3r_aw.jpg

 

When it was introduced in 1987, the FZR1000 was the sport bike. It was a class leader in handling, performance, Delta Box frame technology and 5 valves per cylinder Genesis engine design. The GSXR 1100 was cheaper but not such a good performer and later, in the 90’s, the CBR900 Fire blade was created and started to compete with the FZR1000. The competition between these bikes continued with the evaluated models, Yamaha YZF R1 and Honda CBR1000RR

 

The FZR1000 Genesis is a milestone model as it marked the transition from 2 strokes to 4 stroke super sport motorcycles. This shift represented a new generation of high performance big bikes, which employed Yamaha racing technology from the track.

The first FZR1000 Genesis, presented to the public at the Cologne IFMA motorcycle show in Germany on September 18, 1986 continued the success of it’s supersport predecessors, the RD 350 and RD 500.

 

Exterior

 

For 1989, Yamaha redesigned their biggest sport bike from the tires up, and it felt different. The new bike felt smaller, lighter and lower, though radical improvements became apparent out on the road. The bike got it seat redesigned becoming wider and the ergonomics were repositioned, making it more comfortable.

The FZR1000 was considered by many to be the best 1000 available when it was introduced in 1987. There have been no major revisions to the FZR’s design with the exception of substituting a single headlight in 91 and 92 years and adding four-pot brake calipers after 89. The ram-air was modified in 91 and 92 models. In its last years of production, the FZR was redesigned to its initial 2 headlights design and it stood like that until it exited production, in 1996.

 

Technical

 

The bike’s power plant was a water-cooled, 989cc engine whose angled-forward cylinder layout and DOHC, 20-valve cylinder format that had been introduced on the FZ750 two years earlier. This engine developed 130 bhp at 10000 RPM but Yamaha increased the engine’s displacement in 1989 to a 1002cc, developing a 145 bhp at10000 RPM and it was named Yamaha FZR1000 EXUP. The EXUP system boosted performance and torque and it was first to be used on a 4 stroke engine. The Exhaust Ultimate Power valve is an exhaust control system still used on the YZF R1 in a refined form, which controls the exhaust gas flow depending on the engine’s revolutions.

Yamaha YZF-R1

 

The Yamaha YZF-R1, introduced in 1998, is Yamaha Motor Company's third generation super sport motorcycle.

 

===============================================

 

1998

Yamaha launched the YZF-R1 after redesigning the Genesis engine to offset the crankshaft, gearbox input and output shafts and this "compacting" of the engine yielded a huge dividend in that the total engine length was now very short. This allowed the wheelbase to be shortened significantly which resulted in much quicker handling and an optimized center of gravity.

 

The launch model Yamaha YZF-R1 was available in white/red or blue. In Europe the blue proved to be the most popular and was in very short supply, added to by early models being subject to a worldwide recall for a clutch problem. This bike has a compression ratio of 12.4:1. with a 6-speed w/multi-plate clutch transmission. Yamaha today describe the launch R1 as the true value of "Kando".

 

===============================================

 

1999

The '99 version of the R1 saw only minor changes, apart from paint and graphics. Notably improvements were a redesigned gear change linkage and the gear change shaft length which was increased for better gear shifting. Fuel tank reserve capacity was reduced from 5.5 liters to 4.0 liters, while the total fuel tank capacity was unchanged at 18 liters. A second worldwide recall to change a coolant hose clamp under the fuel tank which could under hard use come adrift affected the early 1999 models, with all 1998 models were all recalled.

 

===============================================

 

http://i249.photobucket.com/albums/gg219/SBF_Yamaha_SportBike/YZF%20R1/01r1_red_3-01.jpg

2000 - 2001

In 2000, Yamaha introduced a series of changes to improve the bike, plus minor changes to the body work to allow for better long duration ride handling. The R1 was an excellent bike to live with on short runs, but due to its quick handling was not a favorite longer run bike. Yamaha's main design goal was to sharpen the pre-existing bike and not redesign it. Even so they instituted over 150 changes in hopes of making an already light, sleek and mean motorcycle even lighter, sleeker and meaner. For example, even with the addition of the new Air Induction System, which weighs four pounds, the overall weight of the bike is down five pounds to a claimed 385 pounds dry. At a claimed 150 horsepower at the crank, top-end output remains the same but changes to the engine management system are supposed to result in a smoother, broader distribution of power.The bodywork is still unmistakably R1 although a few changes were made resulting in a 3% reduction in the drag coefficient. The headlight housing has a sharper profile, the side panels are more aerodynamic and slippery and the windscreen has been reshaped for better rider protection. In fact the bodywork changed so much that bodywork from previous R1s will not fit the Y2K edition.

 

Also updated is the seating area. The fuel tank is reshaped with a more relaxed rear angle and deeper leg recesses to provide for better rider feel. The seat extends further towards the front of the tank and the new, steeper seating position puts additional weight on the front end. All of this is aimed at improving weight bias and offering sharper cornering and more stability. Again, the resounding theme here is to sharpen what was already a very sharp package. The carburetors have been rejetted in an effort to improve throttle response -- especially in the low end -- all the way up to the bike's 11,750 rpm redline. The redesigned camshafts are lighter and use internal oil ways to lubricate journals that, when combined with reduced tapped clearance, provide less friction and create less engine noise. Also changed within the crankcase is the gearbox featuring a taller first gear, a hollow chrome-moly shift-shaft with an additional bearing and a completely redesigned shift linkage and foot pedal. These changes are aimed at nixing last year's transmission complaints as well as helping to transfer as seamlessly as possible the R1's prodigious power to the pavement.

 

2001 was the first year the R1 was truly beaten in performance numbers. The Suzuki GSX-R1000, weighed about the same but produced a bit more power and torque. This also marked the last year that Yamaha used a carburetors engine in the R1. Subsequent R1s would employ a fuel injection system.

 

===============================================

 

http://i249.photobucket.com/albums/gg219/SBF_Yamaha_SportBike/YZF%20R1/02_R1_BLUE_3-01.jpg http://i249.photobucket.com/albums/gg219/SBF_Yamaha_SportBike/YZF%20R1/03r1_blu_3.jpg

2002 - 2003

A new fuel injection system was introduced for the 2002 year, which worked like a carburetor by employing a CV carburetor slide controlled by vacuum created by the engine. With a similar power output to the 2001 bike, the engine was developed (larger bore, shorter stroke) to rev higher, faster and for longer. For 2003, the only change was the choice of colors. The previous years all had a "Red" option, but this was replaced by a black with red flames "Special Edition" which cost an extra $100. Also in 2002, Yamaha released the newly developed "Deltabox III" frame, which, with its hydroformed construction, dramatically reduced the total number of frame welds, thereby greatly improving the frame's strength and torsional rigidity. The rear end of the motorcycle was updated and streamlined with an LED taillight. This allowed for very clean rear body lines when choosing one of several common aftermarket modifications, such as removal of the turn signal stalks and stock licence plate bracket; and replacing them with assorted available replacements that "hug" the body or frame. Also, front end lighting was improved in 2002, between the higher definition headlights and also side "parking" lights within the twin-headlight panel, giving more aftermarket possiblities to remove the front blinkers and utilize these front lights as directional or hazzard markers while stopped.

2004 - 2005

With the competition advancing, Yamaha took to a major development. This included style updates like an underseat exhaust, and performance upgrades including radial brakes and for the first time on an R1 Ram-air intake. Furthermore, the wheelie-tendency known from earlier productions is drastically reduced by changing frame geometry and weight properties. The all new engine (no longer used as a stressed member of the chassis) featured a separate top crankcase and cylinder block. The 2004 R1 produces a stated 172 hp at the crankshaft (excluding RamAir) and also weighs 172 kilograms, giving it a theoretical 1:1 power-to-weight ratio. Also newly added for this year was a factory installed steering damper. Combined with the changes to the frame, it helped to eliminate the tendency of the handlebars to shake violently during rapid acceleration or more so during deceleration on downgrade and less-than-perfect surfaces (aka "tank slapping").

2006

In 06, Yamaha is now mated with a 180 hp at the flywheel. In addition, due to acceleration instability, the swingarm was extended 20 mm longer. Also, in 2006 the 50th anniversary of Yamaha racing in America, Yamaha released a Limited Edition yellow/white/black bike in original Yamaha racing colors. They also made a limited edition model (LE/SP) featured a kenny roberts replica paint pattern with yellow and black paint, front and rear custom Öhlins suspension units developed by the people who work on the YZR-M1 MotoGP bike. Custom forged aluminum Marchesini wheels specifically designed for the LE remove nearly a pound of unsprung weight. A back torque-limiting slipper clutch and an integrated lap timer switch on the right handle bar round out the package making the LE more of a production racer, and Brembo brakes. It has an MSRP of $18,000 and only 500 units made for the United States.

2007 - 2008

An all-new YZF-R1 for the 2007 model year was announced on 9 October, 2006. Key features include an all-new inline four-cylinder engine; going back to a more conventional 4-valve per cylinder rather than Yamaha's trade mark 5-valve genesis layout. Other new features are the Yamaha Chip Control Intake (YCC-I) electronic variable-length intake funnel system, Yamaha Chip Control Throttle (YCC-T) fly-by-wire throttle system, slipper-type clutch, all-new aluminum Deltabox frame and swingarm, six-piston radial-mount front brake calipers with 310 mm discs, a wider radiator, and M1 styling on the new large ram-air ports in the front fairing. 2008 brought BNG and the ability to buy limited edition Fiat plastics.
