I just got to ride my 00 426 last weekend for the first time on an MX track, and have mixed feelings about the bike. I like the smooth power, but it seems like the bike wears me out much quicker than the 99 RM250 I had. The other thing I had trouble with was not using the clutch in turns. I was on a kind of small track, and I don't really see how you can come out of tight turns quickly without using the clutch a bit. I probably need some more time on the bike, but I'm thinking I might have messed up switching from a 250 to this bike. Anyone else have trouble adapting to this bike?
