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. Manufactured from aircraft quality 7075 T651 plate aluminum. High strength and very light weight. Wide range of sizes available. Requires use of 428 chain and front sprocket.
