From last seven months m getting average about 42 to 45 per km on city roads or on highway, i have driven ma bike upto 120 kmph and still i have got an average about 40 to 41 kmph and its not bad. this bike dosent shake or vibrate. one more tip personaly change the front to lil more thich and wider tyre as the front tyre is very risky even on small piece of stone. thanks regards CRAZY YOGI
