Description
A lighter front sprocket translates directly to quicker acceleration and sharper throttle response—critical advantages whether you’re launching on the track or navigating technical terrain. The Renthal 13-tooth design pairs aggressive power delivery with the durability needed for competitive riding, thanks to its case-hardened 655M13 nickel-chromium steel construction and self-cleaning tooth geometry that resists mud accumulation and premature wear.
If you’re running a 420 chain on your Kawasaki KX and want measurable performance gains without fabrication, this CNC-machined front sprocket is a bolt-on upgrade that pays dividends in feel and reliability.
