ultimax 3

[jeffxr]

This belt is reccomended (by Some) for 01 SXR700, but the application charts spec out the ultimax XS instead, I just bought U3, PN 138-4432U3,
is this right or do you really need the XS ($30 more).

I have that belt on mine, it will work just fine.

I agree with the wear issue. The aftermarket belts are made from a softer compound rubber. Also top end sacrafice cause the belt actually pinches together under load. IMHO buy stock Yamaha.

But they say that the softer compound grips better therefore less cluth slippage, less clutch heat and due to the better grip higher top end.

I've been running ultimax 3 belt for 4 years with NO problems. You've already got it so why not try it?

ultimax 3 is great for drag racing because it grips better off the line, but it WILL slow you down on top end about 5 mph in 1000', I use an 8ch for drag racing and an 8dn for radar run's, last week I ran an 8dn and went 98.5mph in 1000' versus an 8ch at 92 mph in 1000', it also went 90 with an ultimax 3, that's with a stock 500cc yamaha.

Right, this is what I meant. These are great for out of the hole but suffers in reliability and top end. XSIVHP, Glad you got long life from yours. I do keep one in my belt holder as a spare but I prefer stock Yami belts.
