Just putting my two cents in. I ride, and will only ride a trx250r but if I did go for a 4-stroke it would be the c-dale. Where I live these things go for dirt cheap in the trader but I can't figure out why. They seem like such innovative and interesting machines. An aluminum frame, EFI, and rezzy shocks! These things are as outageous and innovative as the 250R was in the day. Most think that the YFZ started all of this new age race quads stuff....but heres a 2-stroker who admits the c-dale started it all.

 

Most dont even realize cannondale had a prototype quad way back when the 400ex came out. To bad they decided to focus on the bikes release.
