Hi ! I'm from VietNam, sorry i'm not good at English much :)
My bike is Yamaha Exciter 2011 (Sniper - Jupiter Mx 2011), all stock !!!
I have two type of wheel:
---The first one, i use a standard wheel (front: 17 x 1.6, rear: 17 x 2.5), and standard tire (front: 70/90, rear: 100/70) and of course standard sprocket 14-38.
---The second one, i use a Yamaha ZR125's wheel (front: 17 x 1.6, rear: 17 x 1.85), and standard tire (front: 70/90, rear: 100/70) and of course standard sprocket 14-38. The ZR125's is much heavy than the standard wheel. Tire Circum-ference is little bigger than the standard wheel.
My question is, should i use sprocket 14-39 for the second tybe of wheel (ZR125) ?, does it decrease my top speed ?

Hello i from malaysia. Just bought 135lc 5 speed 2014. All in standard part. What the best spocket to get top speed.:help:


if you will base on the stock wheel exterior, perhaps the reading of traxxas is quite different from stock since he is using bigger wheels compared to the stock wheel. Further, if you change your wheel size, it will also affect the centripetal acceleration, means, the bigger the wheel, the slower the pivot point (hub) rotates..
