JT DRIVE CHAIN 420HDR Chain Kit (12-52-128)
Designed for urban rides and small engines, this chain kit combines a super-reinforced 420HDR chain with a front sprocket and a rear sprocket made of steel. Ideal for replacing worn transmission components, it offers a complete solution to get your drivetrain back in working order.
The O-rings enhance internal lubrication and help extend the chain's lifespan in urban riding conditions (frequent stops, accelerations). The steel tooth manufacturing ensures a good fit with the 420 pitch for a smooth and jerk-free power transfer.
