The Tsubaki Offroad Chain 420 MXC in 134-link length is a high-quality non-sealed drive chain engineered for demanding motocross, enduro and dirt-track part of Tsubaki's MXC series, it is developed in cooperation with professional MX racing teams to deliver reliable power transmission, low friction and reduced rotating mass on lightweight offroad motorcycles that use a 420-pitch chain.
Key Features
- 420-pitch offroad drive chain with 134 links, suitable for motorcycles and offroad machines designed for 420 chains.
- MXC competition series developed together with top European MXGP motocross teams for professional dirt-track performance.
- Non-sealed construction (no O-rings or X-rings) for minimal friction, very low weight and direct power transfer to the rear wheel.
- Solid roller design with high-quality components for stable engagement with matching sprockets and consistent performance under offroad loads.
- Press-fit, quad-stake riveted pins (MXC series feature) for increased resistance to stretching and improved overall chain strength.
- Gold / gold finish for a premium appearance and added surface protection against dirt and corrosion.

Design and Construction Details
The MXC series is designed specifically for motocross and offroad racing conditions, where mud, sand and frequent cleaning demand a robust yet low-friction non-sealed layout reduces drag compared with sealed chains, while solid rollers and precisely formed bushings help distribute load evenly across the sprocket -staked, press-fit pins increase resistance to elongation under repeated acceleration and braking, supporting a stable final drive ratio over time when correctly maintained.
Typical Use Cases
This 420 MXC 134-link chain is suited for offroad motorcycles and pit bikes that are factory-specified with a 420-pitch chain and require a longer length that can be shortened during applications include:
- Youth and small-displacement motocross bikes using 420 drive chains.
- Offroad playbikes and pit bikes set up for dirt, sand or hardpack tracks.
- Lightweight enduro and trail bikes where low rotating mass and quick response are preferred.
- Motocross and practice machines that are cleaned and serviced frequently, benefiting from the easy maintenance of a non-sealed chain.
Installation Notes (General Information)
The 134-link length offers flexibility for different sprocket combinations and swingarm lengths, as links can be removed to achieve the correct chain length for the specific motorcycle and gearing optimal performance and service life, the chain must be paired with compatible 420-pitch front and rear sprockets and maintained with appropriate cleaning and lubrication products suitable for non-sealed chains.
