Tsubaki Offroad Chain 520 MXC 130 links 55316520130

The Tsubaki 520 MXC offroad chain with 130 links is a non-sealed, competition-focused drive chain developed together with leading MX racing teams for demanding motocross and off-road use.

Key features

Non-sealed MXC series chain without O- or X-rings, minimizing friction and rotating mass so that engine power is transmitted efficiently to the rear wheel.
Standard 520 pitch chain with 130 links, suitable for modern off-road motorcycles using 520 final drive components and allowing custom gearing and wheelbase adjustments.
Solid roller construction with press-fit, quad-stake riveted pins for high tensile strength and resistance to stretching and impact loads in harsh off-road conditions.
Gold-finished outer plates for basic corrosion protection and a clean factory racing look.
Engineered specifically for motocross and off-road applications where regular cleaning and lubrication of a lightweight, non-sealed chain is preferred over the added weight of sealed designs.
