BELTS, CHAINS & SPROCKETS
JT SPROCKETS
Computer designed to achieve ultimate strength at minimum weight
JT combines leading-edge technology with top materials to produce the
ultimate quality sprocket range with unbeatable value
Every sprocket meets or exceeds the highest possible quality standards
Sprockets are heat-treated and beadblasted to reduce material
surface tension
Front sprockets are made with top-quality Japanese C45 high carbon steel and
SCM415 chromoly steel alloy
Steel rear sprockets are made with top-quality Japanese C45 high carbon steel
Aluminum rear sprockets are made with high strength Austrian 7075 T-6
anodized aluminum
JT aluminum sprockets are about 30% lighter than a comparable steel
equivalent, which reduces un-sprung rotating weight and
improves performance
Lightweight front sprockets available for some applications
RUBBER CUSHIONED FRONT SPROCKETS (FOOTNOTED)
Used by the major Japanese motorcycle manufacturers since early 1990’s to
dampen the chain impact on the teeth of the front sprocket
These same sprockets are now available to the aftermarket for some models
Quality, design and OEM proven technology are the same as used for what is
supplied to the motorcycle manufacturers
NOTE: When installing sprockets which differ from the OEM size, check for proper
clearances before operating.
