How do Gates Xtreme belts compare to Carlisle Ultimax3 belts? I've had pretty good luck with the Ultimax3 belts, just on REV's though.

Call Felkers in Loveland, CO. Lynn has a "new" Gates belt that works awesome! He spent all last year working on it with Gates and has a new one this season. 970-667-1300 Ask for Brooke.
Tried both
Gates and Carlisle last season prior to fixing my xp. Both lasted about the same, better than the 166 but not as good as the 377. The sizes are a bit different as the Gates was a bit shorter and narrower I think. Gates was a better price.
S
What does the Gates go for?
I think under $50 in U.S. and near $75-$80 in Canada at NAPA
T
I just ordered one. $59 here is Lewistank. I will post back results. I think I should be able to run it as my belt temps have reduced more than double from stock setup..We will see...
T
Finally put this belt on. have about 80 miles on it so far. Still looks brand new.
Performance is better than the 377. the clutches seem to be able to hold the belt much better. If it holds up I will never buy a BRP belt again.

Gates 4320
Used 9 belts last year. Two Gates, they lasted longer than 166 and xs803 but not the 377.
I now have alignment and am 7 rides with the 377. Shockwave has helped clutch temps along with the 860kit pulling a 130-260, net effect better grip on primary vs secondary. Even out slip on front with more grip up front that is and has been lacking with the new qrs.
I think with changes the Gates would be fine.

Gates is the way to go.
Tested on my XP and no change in rpm or performance over the 377....... and 1/3 the price.
Im sold!

The only problem with Gates belts is they give you about zero warning before they let go... and when they go it's like a grenade going off under your hood, and the damage to go with it. Most belts will pitch a string or smell hot, but the Gates just explodes into about 400 little pieces and typically takes anything in the vacinity with it...belt guard, footrest, speedo cable etc....
I'e had the best luck with factory belts, as has just about everyone I ride with.

Yep! I just grenaded two Gates in the last two rides. No "hair" on the vents, no warning. Just a GIGANTIC BOOM while in the middle of a turn while highmarking. Very exciting indeed I'm going back to the 377's.

How many miles on them?? Anyone tried going back to the 166's with the stock clutching out??

Another question is why is it's weird to me the gates belt blows different. You know BRP is not making their own belts. Most of these belts are made by the same manufacture so I cannot see a huge difference.
I believe Doo belts are mfg's by Mitsuboshi....I could be wrong.
