Was just thinking. Why not ask the experts? John Nicolas has ties with maico so he must be able to ask which new maico is fastest on an average motox track. As i saw they manufacture 250, 320 ,500, 620 and 685. The difference in weight is only 3 kilo. So as far as i can seen the same bike just different engine.
Which is the fastest round a track and more interesting WHY? I bet the 685 is not the fastest.
