I was wonderin what happen when you change the sprockets on the bike??? Is it for torque??? More Acc.????More Power in general??? Would i change just teh front or just rear or maybe both??? if anybody knows please help??? i have a 88 rm250
one down on the front sproket is approximately the same as 2 1/2 up in the rear. Gains are in accel but you lose about 8% on top end. If you go up on the front sproket then you get just the opposite.
