Everyone asks me this. I have not tested the 08 yet and I moved to the 636 from the 250R. I have no way of comparing power. I didnt really ride the 636 to the limit so I dont think I'll miss the extra 37ccsWhat drove you to replace the 636 with the '08? Just curious.
The 08 is newer, has less miles, and looks pretty. Its not all about power I hope.
