JT DRIVE CHAIN 428HDR 428 — manufacturer ref. JTC428HDR124SL. Standard reinforced chain designed for low displacement machines and light trails/cross bikes. Made from steel alloy to optimize link strength without breaking the budget, it is aimed at urban riders as well as amateur off-road enthusiasts and owners of compact quads and roadsters.
The 428HDR is easy to install and provides a reliable solution for the primary transmission of small displacements. It is suitable for maintenance reassemblies and standard replacements on 50cc motorcycles as well as on certain 125 cc models, particularly compact ones where a robust and economical chain is preferred over a high-end O-ring solution.
