By more tractable I mean more linear power application. I thought tractable was the preferred nomeclature. I understand your point of throwing parroting back at me, but remember I am using a learned term (yes, I did not coin this term) for a characteristic I have personally felt riding both a WR450 and EXC200. I am not commenting on the riding characteristics of bikes I have never ridden.
It seems to me that it is very in vogue right not to dump on 4 strokes while quickly forgetting their benefits. I have a theory that some may just be retaliating against their first 4 stroke, new top end, maintenance bill and saying well forget 4 strokes, we should all go back to 2 strokes. I have nothing to back this up it is just a theory.
I can climb hills on my xr250 too. In certain circumstances I feel it is easier on my wr450. In my personal experience it takes less attention to shifting and momentum keeping on a more powerful bike when climbing tough hills.
Just having a little fun with you...
I ride/race a wr450 and I know that when its near the end of the race and I'm tired as hell and I come up to a big hill, I can just put it in second, twist the throttle and let the bike crawl up the hill. When its a 450, you give it more throttle and resist the temptation to use the clutch. Its definitely easier at that point. However, if I wasn't on a 450, I would be so damn tired to begin with.
450's are good, great even. but if you race them, only the best riders will get the maximum benefit. Lighter is better.
