hi Guys
Just to clarify the Superstomp crf50 type bikes are 77cm seat height, its only the Juicebox and Bullet thats 65cm
When you are looking at 140cc bikes they accelerate much quicker than 125's and you notice this after riding both. £100 will never make a 125 into a 140, so think what you want before you spend, dont go chasing more power after you buy a 125, but then again, that can be said of a 140 and 160cc , where do you draw the line?
As for power, at the risk of repeating ourselves, its only the Stomps and WPB's that fit a Z40 race cam, giving a 1-2hp edge on all the other bikes.
To back this up its only the Stomps and the WPB's that are required to detune and to be made slower to compete in Standard 140 class races
Hope this helps
