Product Overview
The Tsubaki Offroad Chain 420 MXC 108 links is a high-performance, non-sealed 420-pitch drive chain from Tsubaki's MXC off-road series, developed in cooperation with leading European MXGP motocross teams to deliver maximum reliability and power transfer on demanding dirt, sand and mud tracks.
This specific variant provides 108 links for motorcycles that require a compact 420-pitch chain length, making it suitable for many small-displacement off-road machines when used with matching 420 sprockets and correctly specified gearing.
Key Features
- Off-road specific 420 MXC chain engineered for motocross, enduro, trial and other demanding dirt applications.
- Non-sealed (no O-ring/X-ring) construction to minimise friction and rotating mass, ensuring efficient power delivery to the rear wheel.
- 108-link length for motorcycles that specify a 420-pitch, 108-link chain in combination with suitable front and rear sprockets.
- Gold-coloured plates that combine a premium appearance with corrosion resistance and easy visual inspection of lubrication and wear.
- Precision-manufactured pins, bushings and rollers for consistent engagement with sprocket teeth and stable service life when properly maintained.

Typical Use Cases
The Tsubaki Offroad Chain 420 MXC 108 links is suitable for a wide range of off-road motorcycles that use 420-pitch chains and require a 108-link length, including many small-displacement motocross, enduro and trail models when combined with the appropriate sprocket sizes.
- Replacement drive chain for off-road motorcycles originally equipped with a 420-pitch, 108-link chain.
- Performance-focused motocross or enduro builds where reduced friction and rotating mass are prioritised over the extended service intervals of sealed chains.
- Standardisation on a proven racing-grade MXC series chain across multiple 420 applications within a workshop or race team.
Performance Benefits
- Low friction, non-sealed design helps more engine power reach the rear wheel, supporting strong acceleration and responsive throttle behaviour.
- Lightweight construction reduces unsprung and rotating mass in the final drive, contributing to agile handling and quick direction changes on tight tracks.
- High-quality materials and tight manufacturing tolerances provide predictable elongation characteristics and consistent performance over the chain’s service life when correctly cleaned and lubricated.
- Gold finish offers visual appeal while helping to protect the chain from corrosion in wet and muddy off-road conditions.
Installation and Compatibility Notes
This chain is intended for motorcycles that use 420-pitch front and rear sprockets and require a 108-link chain chain length compatibility depends on the specific sprocket tooth counts and swingarm geometry of each installation, the chain must be matched to correctly sized sprockets, joined with the appropriate type of connecting link for the MXC series, and adjusted to the chain slack specified by the motorcycle manufacturer.
