This weekend I rode my buddies YZ 426F for a few hours and coming from my modified KLX 300 the bike was a blast to ride! In 3rd you just hit it and the front comes right up and it felt like riding a blue rocketship! I do mostly trail riding though and I think the next bike I get will be an electric start. Does anyone know what the power and feel differences might be compared to the 426 if I go with a WR 450? I do go to the track, but not often. Do you think the WR could perform OK on the track if set up before hand? Thanks for the info, I think I'll be making a move from Green to Blue soon!
