I just read the first media published review on the 08 450 that I could find. Its a e-magazine available online only (I believe). They tested the european release of the 450 (no shorty exhaust). The review was very favorable, and different from some of the comments I've seen thus far. Of course everyone has agreed that the handling and turning are now superb. The reviewers, however, felt the motor improved in power compared to the 2007. They did not say there was more power down low, but said it is more responsive and has a more "racing characteristic." On the other hand, the said the kayaba forks are inferior to their showa counterparts. So what does this mean (to me anyway)? I almost bought the 08, then hesitated after hearing the motor is weak. Maybe its just the exhaust. So now I'm thinking about it again. Anyway, I can't mention the direct source, but if you do an internet search that includes motocross and digital in the parameters, you'll turn up something that you can download and read yourself. Make your own conclusions and maybe comment here.
