Sorry 125cc guys. I need a 250. My 250 Big Ruckus naked scooter goes 65 on the freeway. Faster, actually. 80+ on the downhill for the brave. I go for long cruises. Have to go on freeways someimes. The Big Ruckus kicks ass compared to 125s with little FE penalty. And it sounds like a motorcycle!
Look, this thread is not complete without seeing what Craig Vetter has done with the Honda 250 belt drive:
