Rk 428 Mxz Drive Chain

The RK 428 MXZ Drive Chain is engineered for motocross racers who demand superior performance and reliability. Built with high-quality materials and advanced manufacturing techniques, this chain delivers exceptional strength and durability for off-road and street applications.

Description

This RK 428 MXZ drive chain provides exceptional tensile strength of 25.8 kN (5798 lb), ensuring reliable power transfer and longevity. Designed for both off-road (up to 125cc) and street (up to 250cc) motorcycles, this chain is constructed from high-grade medium carbon alloy steel. Each component is meticulously shot-peened and heat-treated to maximize its resistance to wear and fatigue. The chromoly steel construction, combined with seamless rollers and bushings, and oversized alloy pins, enhances the chain's overall strength and performance. Pre-stressed and pre-stretched during manufacturing, the RK 428 MXZ chain minimizes maintenance and ensures consistent load distribution throughout its lifespan. The natural finish provides a clean, professional look, making it a perfect upgrade for any serious rider.
