Description
The Renthal CRF150F 428 Conversion Kit is designed to improve acceleration and responsiveness by reducing weight. This kit replaces the stock 520 O-ring chain and steel rear sprocket, saving over 2 lbs. of rotating mass. It includes a gold Renthal R1-428 chain along with front and rear sprockets that maintain the stock gear ratio. The front sprocket is crafted from durable nickel chromoly and features grooves to clear mud and extend chain life. The rear sprocket is precision-machined from 7075-T6 aluminum, incorporating self-cleaning mud grooves and lightening holes for optimal performance.
