One way to improve the performance of your CRF150/230F is to convert the final drive chain and sprockets from 520 chain to 428 chain. The standard 520 chain is very heavy and has some un-needed rolling resistance at the rear wheel. By converting to 428 chain you will reduce the extra weight and improve rolling resistance boosting overall overall performance. This countershaft sprocket is manufactured from Pro quality grade chromoly steel approaching 200,000 PSI yield. Case hardened, finished with electroless nickel plating. Range of sizes available. Requires use of 428 chain and rear sprocket.           • Chromoly steel • 200,000 PSI yield • Case hardened • Uses 428 chain           This item must be matched to a 428 chain and 428 rear sprocket.
