I am 28, race hare scrambles and Cross Countries, 05 was my first year pro. Raced my ktm the last 2 years and am now looking at an 06 450f. I test rode an 05 from my local dealership. I think it has stock gearing (14:50 was on it) so I was stalling it a lot. First gear felt as fast as my 2nd on the ktm. But once the trail opened up the yz suspension, handling, really made me smile. That ktm was a great motorcycle but the front end was a little scary so this bike feels like butter. Knowing that the 06 has the 5 speed will already help the fact that I kept stalling it and that it was to jumpy, a little aggresive. If I could tone it down a little and smooth it out, I would have the ultimate race weapon. My riding position will have to change, and will adapt with time. I am thinking of adding a 12-14oz flywheel and going one, or two teeth smaller on the front sprocket. These few changes with the 5 speed should make the difference. This bike has plenty of power, I am not interested in adding hp just smoothing it out, a melower hit off the bottom. any more suggestions?
