Eh, why worry about the belt on bike?

I can't speark for other brands, but the drive belt on the Vision - an 850 lb machine with about 100 TQ at the rear wheel - has a maintenace replacement interval at 30,000 miles.

I had mine changed around 30,000 with a rear tire change so it wasn't a big deal. It was barely worn and the mechanic told me it would have probably lasted to 50,000 miles or more.


At the change interval its not just as simple as dropping the tire usually. Changing a belt typically means dropping the swing arm, and on most big twin Harleys it also meanz pulling the primary drive as well.
While belts do last a long time normally, one rock can change that drastically in a matter of seconds. Belts are quieter but who can hear a chain over the sound of the motor anyway right.
If ya want the best I suggest an episode of Penn and Tellers show called ******. The episode in which they address the idea of "the best".
I share their opinion on the matter and you just might also.

I have no faith in human perfectability. I think that human exertion will have no appreciable effect upon humanity. Man is now only more active - not more happy - nor more wise, than he was 6000 years ago. Edgar Allan Poe
