Hi all,


Does anyone have a service manual for a CB400 SuperFour? I tried a few searches (in Google and on this forum), but I couldn't find anything. My bike is a VTEC Ver. 1 (model year 2000), but I would be happy to look at a service manual for any version of the SuperFour. I do have an English owner's manual, but not the service manual.


Thank you for any help. This is my first post to this forum, but I have often checked it before when I had some questions about my bike.

Hi, I just bought a new Honda CB400X last month and the dealer lowered the seat by adjusting the triangular plate (I think called the low link plate) linking the monoshock and the swing arm. Is it safe and legal. Today I tried to adjust the monoshock as it was too bouncy even with my wife seating on it. However, I found that the monoshock was actually sitting on the triangular plate (that was rotated to lower its height by the shop mechanic) and I could not turn the knobs.


From what I know we can purchase a smaller "low link plate" to safely lower the overall seat height from online motorcycle parts dealers from http://japan.webike.net/products/21870827.html


I do not have the photo of the original position of the triangular plate but only after the rotated position done by the dealer. You can see the arrow (possibly showing the correct down position). Can someone post the original position or provide some technical advice whether I should acquire the smaller "low link plate" from the Japan website rather go along with the solution provided by the dealer and whether it is safe to continue doing so. Appreciate your replies. Thanks.

From what I understand, Boon Siew has stopped bringing Super 4 to concentrate on the new dual cylinder 400cc bikes (400x, 400f, cbr400). You can however, find new Super 4 CB400 Revo from parallel importers if you don't mind.




Couldn't see the Super 4 on boonsiew website. Or has it been discontinued?

Maybe you are not getting a response because this is the CB400 Super Four forum, and the people here are not familiar with the CB400X (which, despite the CB400 moniker, is not a Super Four)? Or they don't know about monoshocks because the Super Fours don't have them?


You may get better results in the the Tourer forum.

Except SG Boon Siew, most of other shop selling S4.

Some concern about the warranty & recall not cover the PI bike, dont worry all under cover.

Haha, me too. I considered the Super 4 and 400F and 400X (the latter 2 are essentially same bike but with slightly different seating posture and cosmetics), but decided on the Super4. No regrets. The S4 may not look as modern as it's younger siblings, but it's fun to rev and ride, feels very solid and the 4 cylinders sound great.


I still prefer super 4 to 400x

      Hi all, sorry if I posted in the wrong forum category.

      I am relatively new rider, and my bike's COE ends in May. The bike is eligible for the $3500 NEA rebate as well.
      As I have never done it before, can someone guide me through the process? Also, are there any specific important things to look out for
      in case I get cheated or get into trouble etc.

      The Honda ADV150 has a built-in power cut in the stock ECU.
      Most ADV150 riders would have experience this power cut when approaching speeds of 110km/h-120km/h shown on the speedometer.
      This is entirely normal as is what is referred to as a speed / power cut to protect the engine and the other components of the ADV150 as a Class 2B scooter is not made to go much faster than that.
      There is a workaround to this power cut (if so you wish) and that would be changing to an aftermarket ECU that does not have this built-in power cut.
      If you want to remove this power cut, it will void your original manufacturer warranty is is highly NOT recommended, it is also unsafe for the motorcycle and the rider.

      Looks pretty good, probably will look even better on the white version!

      Thanks to bro Fadli for the picture. Took him a lot of time, elbow grease as well as thinner to remove all the stickers.
      Has anyone else tried this one their ADV150? Looking forward to seeing a white unit that has its decals removed.

      Honda gives its CB1000R naked some love for 2021 with a sophisticated blacked-out look and a few choice upgrades. The bike will be available this May starting at S$TBC. Although it will be available to dealers in May, it doesn't mean you will be able to get one in May however. We must apologise in advance as we understand from Boon Siew Honda that they will not be bringing in the Black Edition of the Honda CB1000R until the current 2020 models have been sold out - and who knows how long that would take!

      The new styling gives the machine its 2021 moniker, the CB1000R Black Edition, and touches just about every visible part of the bike. Honda used black plating and black anodizing techniques on the subframe, swingarm pivot plates, exhaust system, front suspension, and handlebar clamp among numerous other places.

      In addition to the bold new colorway, the CB1000R gets a new three-level quickshifter for clutchless upshifts. A slip/assist clutch smooths out wheel hop on hard downshifts.
      Honda fitted a new 5-inch TFT instrument panel to the bike also.

      The CB1000R Black Edition is powered by a 998cc inline-four fit with ride-by-wire and four ride modes. Honda Selectable Torque Control is included to help dial performance in a variety of conditions. It utilizes a steel backbone frame suspended by a Showa SFF Big Piston fork, fully adjustable, and a Showa shock with spring preload and rebound damping adjustability. Four-piston radial-mount calipers grip two full-floating 310mm discs at the front while a single-piston caliper and 256mm disc handle braking duties at the back.

      Honda utilizes LED lighting throughout, highlighted by a classic round headlight that emphasizes the brand’s Neo-Sports Café aesthetic, of which the CB1000R is a hallmark example. Other premium design features include a flangeless fuel tank, aluminum alloy detailing, a new rear splash guard that mounts directly to the swingarm, and a passenger seat cover.

      The only available colorway for 2021 will be, you guessed it, Graphite Black.

      Honda is all set to launch the made-in-India Honda CB350 motorcycle in Japan and other Asian markets as the Honda GB350 Basic Roadster.
      Honda has managed to surprise enthusiasts by launching a India-manufactured premium retro-styled motorcycle late last year as most of its core line of motorcycles are manufactured in Japan. The new Honda GB350 has found lots of takers despite limited availability thanks to its retro classic looks, a crispy exhaust thump and more importantly a powerful performance. Could riders actually be looking towards more no-frills motorcycles that are at the lower end of the pricing spectrum?

      Now, the Japanese manufacturer is planning to launch this bike in other markets around Asia very soon. According to a Japanese magazine, Honda will launch the classic roadster in Japan first and rechristened it as GB350. Made in India – Exported to Japan, Honda has already showcased the motorcycle in Japan and we expect it to be making its rounds to other Asia markets in the near future.
      The GB350 when launched, is already BS6 compliant which is equivalent to Euro 5 emission norms. This is good news as all new motorcycles coming into Singapore would need to adhere to Euro 5 emissions or risk not being able to be on the roads after a few years (remember the NEA debacle?). Hence, Honda wouldn’t have to invest further to upgrade the engine’s emission standards. It is also equipped with ABS as standard in its based model spec, which is very helpful as this is a powerful Class 2A bike that would need up-to-par stopping power. It is highly likely that the Japan-spec GB350 will be the model that is exported overseas.

      While earlier reports indicated that in Japan, the GB350 will cost around JPY 550,000 to JPY 600,000, the latest reports suggest that it would cost around JPY 499,000 instead, which comes in at a lower price than initially expected. Exact prices will be announced soon, once it is launched, and the price is Singapore is dependent on many factors such as COE and road taxes so we'll just have to wait for the official word from Boon Siew Honda.

      The bike is launched as a challenge to Royal Enfield’s 350cc retro segment which currently holds a significant market share is various other countries and could also be why Honda has launched this GB350 as a direct competitor. Also similar to the Royal Enfield, the GB350 comes equipped sparingly and does not even have a digital dash like most motorcycles from 2021 but instead just has a simple analog gauge.

      Initial sales numbers of the GB350 are promising, and it has the potential to disrupt Royal Enfield’s monopoly. Coming to its powertrain, it is powered by a 348cc single-cylinder air-cooled engine which generates 21 bhp at 5500 rpm and a peak torque of 30 Nm at 3000 rpm. Hardware equipped will also remain similar to the Japanese model which consists of telescopic forks at front and dual shock absorbers at rear. Anchorage duties will be handled by disc brakes on both ends.
      What do you think of the Honda GB350? Do you think there is a market within Singapore for a no-frills retro roadster motorcycle? Let us know in the comments section below!
      P.S. Boon Siew please bring this Honda GB350 into Singapore!
