hey i have a CRF 150 2005 and i let my friend ride it (stupid mistake) well he toped it out on the road and a cop clocked him at 80 in a 25 mph zone, it was all stock about 2 montsh old and he was topin it out at 80 so i guess thats as fast as it goes but i dont believe the cop i seriously dont think a stock crf 150 gets up to 80. im tryin to find out the top speed also but thats wat the cop said he clocked him at.
