U dont have to pull the clutch all the way in when shifting gears. U just have to reach the friction point and that’s enough. It removes the jerking when shifting
There's basically more stuff in the original exhaust to make sure it only does 45kmh. Older models are easier to unrestrict the exhaust to make them go 75-80 kmh
if you have a recent motorbike you just need to cut the B5 cable of the control unit which is a limiter, then you can also change exhaust that the stock one contains some “chokes” (idk how to say in english) and also u can change the pinion which in stock bike has 11 teeth with a 14 teeth one
