View source for Drive Belt/Wear

<onlyinclude>
Generally, watch for belt damage and try to anticipate when to replace the belt to avoid an incident on the road where the belt snaps.

;What to Check
* Check the teeth for wear and cracks.
*: If you see cracks in the tooth forming, the belt is getting old.
*: If you see deep cracks starting, it's time to [[#Belt_Replacement|replace the belt]] ASAP.

;When to Replace
* When it snaps.
* When any teeth have been ground off.

;Hard Skips
* If the belt experiences a "hard skip" from debris between the belt and a sprocket, it is likely to fail soon after. Watch it carefully if this happens.

;Tension with aging
: Apparently, [http://electricmotorcycleforum.com/boards/index.php?topic=5693.msg42069#msg42069 per forum user JaimeC], belts don't wear like chains.
: As they get older they'll actually get tighter, not looser like a chain.
:* When a chain ages, the little bearing points between the links and rollers wear causing the chain to hang looser.
:* When a belt ages, the rubber on the inner/toothed side begins to swell.
: Since the Kevlar belt on the outer circumference won't stretch, the inner circumference will shrink making the belt tighter around the sprockets.
: Generally, you want to make sure the belt hasn't gotten any tighter since you brought it home.
