I decided to get a YZ250 2 stroke instead. I ride track once a week and trail once a week here in Utah(desert, high alpine, etc.) I really tried to like the 450 and rode my buddies 2006 YZ450 quite a bit both on track and in the desert. What it boiled down to for me was the weight. I used to have a YZ426 and went back to the 2 stroke because it was such a pig. The 06 450 was much better than my 01 was, but after spending some time on my other buddies 2006 yz250 2-stroke I made the decision. I've gotta say after riding my friends 06 2-stroke I was SO impressed with the suspension and handling. Power wasn't the greatest but it was FUN. However, one of the faster motocross racers in Utah just finally switched from his 2-stroke to a 07 Yamaha 450. He works at a shop that sells Yamaha and Kawi and after riding the 06 450 he decided to pull the trigger. We're lucky to have the options we do. Oh, and I paid $5450 OTD with the 12 mos. same as cash financing. I'll pay it off in less than a year and there will be no finance charges. There were some 2006 YZ250's on cycletrader for $4499. By the time I paid for shipping it was going to be $5475 so my local dealer beat them to get my business. Good prices!
