Just remember, going down 1 tooth in the front is equal to going up 3 teeth on the rear. The Raptor is geared a little high to begin with. Just about everyone goes down to a 12 tooth front sprocket. It actually makes first gear MORE usable as a first gear.

 

yep,,,and not to mention,,,it is a cheap modification,,,,and you can always put your 13t back on if you like

 

Cheap...HEH i wouldnt quite say that....i have a sidewinder setup, its at least 40 for just my front sprocket, 150 for my TI Moly Rear...PLUS if u change one, u change all, this rule may not apply to any of you but it does me, and for me to make gearing changes, its rather pricey.

I am running stock gearing, because when i come out of the trails, i have a 10 mile dirt road, and regular road...ride home.

I went up one tooth on my rear, i lost like 5MPH, it was quite noticeable, i couldnt imagine doin a 12 in the front that just too much in my mind, and i ride hardcore tight technical trails, i dunno maybe i just have enough torque...its right around 56HP

I agree, if one item is worn you replace front and rear sprocket and the chain. A lot of people change the front sprocket right away so you wouldn't have to change all three parts.

 

I agree about replacing bolth but since my quad is fairly new, Im onlly going to replace the front for now with a 12 tooth.
