Hi all, i went to warm up my 2011 rs 125 today and after running for around 3 minutes, he engine suddenly stopped. I tried starting it up again but there was only the cranking sound, the engine could not start. The last time i rode her was last Saturday. Could any bro advise me on the issue?

Hi. I'm new to RS125 and new to bike too. I need help.

1) I bike keeps stalling when I try to move off from stationary position. The side stand was up, and each time I try moving off, it just stalls. I have to throttle a lot then it'll move off, but it'll be too noisy and the power will be too strong. How do I overcome this?

 

2) it's really hard to turn my throttle. It takes a lot of strength just to throttle. Is there something I can do to overcome this? Or is it naturally like that? Should I change the throttle grip? If yes, how do I do it and what to do change it to?

 

Thanks!

left your bike for days without starting up?Make sure the stand is up, or it will keep stalling when you change to gear one.

I got the same issue when moving off, maybe we're not use to 2 stroke bike. But i'm alright now already. Just throttle a little more and release clutch. use the clutch to adjust the speed when moving off

Hi all..i have an upcoming TP for my 2B license and I'm very interested to get an Aprilla RS4 125. After trawling through the forums, it seems that there arent many options for buying a 2nd hand. There is 1 I saw quoted abt 14k COE expiring 2023. Seems abit much for a second hand bike considering the COE was 2k at that time and a new Rs4 125 costs about 17k according to uniquemotors. Is it because I'm noob or are there any reliable websites/shops I could go to for a used aprilla r4 125. Many thanks to the bros here!

Many second hand bikes are sold at profits by direct sellers. Beware. On the other hand, some might be cheaper than shops. What is your budget anyway?

hi....my budget is any reasonable price for a used r4 125. im not a lowballer but neither do i want to be a carrot head. i mean 20 percent off a new bike for a used bike depending on condition plus coe price seems about fair to me. thoughts? thanks!

Guys, can check with you guys if your rs125 choke lever can be pulled all the way down? Just changed my choke cable. I used to be able to pull the choke to maximum only halfway, but now I can pull it all the way down. Is this a cause for concern?

Hi Guys need urgent help! Is Ah seng still at Biz Hub ? When there and it seems like it moved or closed ?

Or any intro workshop for Aprilia ?

 

Thanks

 

I think he is still there, but went for a long CNY holiday and not back yet. Always give him a call before you go down, he's a bit whimsical with his opening hours.

 

What kind of problems are you having? If it's urgent you can probably just drop those industrial parks and ask the shops one by one if they can solve your problem. If you live in the east, there's a rad san speedshop at kaki bukit that does aprilia as well.

That sounds bad, should get ah seng to take a look. According to my experiences with unique motor, they have a tendency to over-diagnose/ jack prices so I wouldn't take their word too seriously. Anw, ah seng quoted me 200 bucks for a new power valve before. But I highly doubt that's a power valve problem. I'm no expert but when my power valve cable broke (55 bucks to replace @ ah seng), I have no problems revving it up all the way to 11k rpm, just that there wont be any power surge past 8k. Yours sounds more like a carburetor problem.

Yo how much you replaced your choke cable and where? I've been running without choke for 2 months cos it snapped.. Just did full engine service and replacing of clutch plates and cable just now, $500 at Jurong Port Road.. And yes lever can be pulled all the way down.

I changed it at motorpoint near my school (NUS) for 63 bucks (48 + 15 labor). Wow 2 mths without choke sounds troublesome. How did you cold start your bike during the 2 mths period?

      To stand out. Always
       
      Developed in close collaboration with Aprilia Racing, Dorsoduro was designed by taking the best features of sports bikes and supermotards, producing a perfect combination of performance, technology and fun. Power, lightness and agility, but also directionality, responsiveness and steering precision are therefore its main characteristics. Aprilia Dorsoduro has components, technical features and finish of the highest quality which contribute to the uniqueness of the project.
       
      Aprilia V90 four-stroke longitudinal 90° V-twin, DOHC, four valves per cylinder.
       
      Three performance modes, Sport, Touring and Rain, can be selected from a switch on the handlebars (with the throttle closed for safety reasons). The Dorsoduro changes its character radically, depending on what mode you select. Sport mode gives you aggressive instant power; Touring mode gives you a smoother action, better suited to relaxed long distance riding; and Rain mode gives you ultimate safety slippery surfaces. The Tri-Map electronic throttle also means smoother, more consistent power thanks to more accurate and precise throttle control based on parameters including engine speed, gear selection, air flow, throttle position and temperature.
       
      Whatever mapping you select, the engine is always ready to deliver the best possible performance in terms of acceleration and rev range, giving you an amazingly satisfying and entertaining ride.
      Super smooth v twin engine
      Never been to track.
       
      A 2nd hand duke 200cc cost about 10 to 12k, you can get this 750cc italian stallion with that kinda price. Also, hypermotard is everywhere and way too common. Be unique!
