My belt started shredding over the weekend. What do people use for replacement belts? Yamaha or ?? This is a stock machine used for trail riding but will hit 100mph on a short lake nearby.

Suggestions?
Thanks....

The Ultimax belts are a slightly softer rubber and thus slightly "stickier". Putting one in a stock clutched machine will give odd clutching issues such as late backshifting. Some people claim higher top speeds from less slippage on the clutches, but I have yet to see any hard evidence of this, and nearly everyone reports an overall poorer feel on the trails. They also don't last as long.

If you shredded a belt, better check your clutch alignment. I've got over 3500 miles on the original stock belt and it's still well within spec with
 
would suggest making sure wether you have an -00 or -01 belt and getting the same as what you had the -01 is a little wider.
 
I had about 1800 miles on the belt before it shredded. I thought they discontinued the 00 belt and I did not have a choice to get the older style belt. I also have a SX Viper that still has the mounted spare so I can use it for the spare on the RX1 if that is any advantage.

Should I search out an 00 belt?
Thanks,

my drive clutch has a groove wore in it with only 3500 miles, always used stock belt, i have always been told aftermarket belts last because they are hard and usually cause this problem with the drive clutch, so not sure what is really better, i did read this info from "Hartman Inc."

The Yamaha 8DN belt is very hard and has a high amount of slipping, which will create heat and loss of acceleration. (The only "good" thing, is that it will last forever). Harder is not better for performance. We use a Dayco Ultimax that is softer, this enabling us to get the drive belt to the top of the Secondary Sheaves on the driven clutch. Dayco has a one year warranty. Buy "two" and you have a lifetime supply of belts. Read the back of the belt sleeve, less slipping is "Free Horsepower".
 
my good buddy dan fisher,witch is a two-time mod ice drag sled national champ told to run dayco-3,he still using one that is 3yrs old,mine has about 2200mi,still banging 126mph....wow what a rush!! :Rockon:
