Description
Fitting a Twinring is the closest thing to a set-and-forget rear sprocket upgrade, combining the wear resistance of steel with a rotating mass much closer to pure aluminum. The design bonds a hardened steel outer chain ring, heated to roughly 200 degrees Celsius during manufacturing, to Renthal’s Ultralight aluminum inner carrier, fusing the two into a single permanent unit rather than a bolted assembly.
What makes the Twinring different:
- Hardened steel chain ring stands up to the abrasive wear that eats through pure aluminum sprockets
- Ultralight aluminum inner keeps unsprung rotating weight down near what a full aluminum sprocket offers
- Steel-to-aluminum bond is permanent for the service life of the sprocket, with no separate fasteners to loosen or inspect
- Grooved tooth face sheds mud and grit that would otherwise pack in against the chain
Sized at 50 teeth for 520 chain and finished in green, this Twinring fits the 2020-22 Kawasaki KLX300R directly, no spacers or adapter plates, and ships from IPD Racing stock. This is part number 1120-520-50GPGN, priced at $152.95, a genuine Renthal Twinring backed by the manufacturer, and IPD Racing can verify exact fitment against your VIN or model year if the 2020-22 Kawasaki KLX300R designation covers more than one variant.
