So I want a little bit more low end power for trail and dune riding... Would you guys recommend a 14 or 13 tooth front sprocket? I want to be able to notice a difference, but not a HUGE difference.

Any info will be greatly appreciated.

I don't know your currnet mods, but I'll say I have a 14 now and am going up to a 15. I can't imagine what a 13 would be like.

Dropping 1 tooth on the front sprocket is like dropping 1 tire size. Your stock front sprocket is a 15T I would go to a 14T. You will notice it with just 1 tooth drop believe me.

The year split I believe is 05 15T front and 06 and up is a 14T front.

If nothing els buy a few dif sizes there like $8 a piece from rocky mountain atv. I love the primary drive sprockets, only things I run is primary drive in aftermarket sprocket and chains.

i did a few things at once, but going from a 15 to a 14 front was a night and day difference.. i can hardly keep the front down now on hard launches :eek2:

i have a 13t and im waiitng on my chain so i can swap it out. my buddy had the same quad as me with a 14 and said it made a big difference. guys say the 13 makes a huge difference. you loose roughly 8-10 mph top end though thats the only downside with a 13.

here a site for you to plug numbers into

my 05 came with a 14. i put on a 13,a huge difference. a lot more bottom end. i ride trails,race in SORCS( hare scrambles). i come off line in 2nd gear. 2nd is like 1.5 ,3rd like2.5.does cut top end,but runing woods don't have a loy of open speed anyway.tight turns and hill climbs ,now it eats them up. best mod you can do.
