motorcycles invariably use O-ring
chains. This contrasts to the
traditional roller chain
. Using o-rings to seal the inner bearing
keeps out foreign matter
(dirt and water) and can translate
to a useful
life of 10-15000 miles.
Older bikes may not be able to fit the wider o-ring chain. Roller chain
needs far more frequent lubrication and cleaning. Even with careful
attention they will last less than 3-5000 miles before the wear of the
chain will accelerate the wear of the sprockets.
