They say the belts are near impossible to break. At Interbike this year they had a Harley Davidson being suspended in the air by one of the belts.

I don't think I could imagine one of the cogs or rings breaking or wearing from a belt, they look very burly.

However, if something were to break, or you need replacement belts, QBP is going to be one of the distributors.

They're also just as efficient as a chain.

Recommended replacement of the belt is over 10,000 miles, there's no oiling, it's much quiter and probably smoother and stiffer under hard accelerating.
