The Renthal R1 428-140L Works Chain is a high-performance, non-O-ring chain specifically designed for off-road and mini racing machines up to 100cc. Engineered for maximum power transfer and durability, it is built to handle the severe stresses of motocross and supercross racing. The chain features shot-peened alloy steel side plates for exceptional tensile strength and impact resistance, as well as chamfered inner links to reduce the risk of derailment. Extended bushings minimize friction between inner and outer link plates, ensuring efficient power transmission. Additional features include case-hardened alloy steel bearing pins for enhanced wear resistance, shot-peened solid rollers for extended service life, and corrosion-resistant gold-colored side plates. With an ultra-high average tensile strength of 5,170 lbs, this lightweight chain delivers reliable performance in demanding conditions. A clip-type link is included for easy installation.
