??? I have an 06 250X and i ride tight slower trails with sudden hill climbs. If i want to change the sprocket to get more low end grunt and dont care about loosing top end speed which sprocket should i change. Should i go bigger in the front or smaller in the rear. Is there an advantage or disadvantage to changing front sprocket over the rear. It seems most threds are about guys changing the rear, but it seems easier and cheaper to swithch the front.Any help will be appreciated.
