Tsubaki Offroad Chain 420 MXC 132 Links
The Tsubaki 420 MXC 132-link offroad chain is a competition-focused, non-sealed drive chain engineered for small-displacement motocross, enduro and trial motorcycles, delivering responsive power transfer and low rotating mass for demanding dirt use.
Key Features
- MXC offroad series chain designed specifically for professional motocross, enduro and trial applications.
- Chain size 420 with 132 links, suitable for many 50–65 cc offroad and youth motocross motorcycles where a 420 pitch is specified.
- Non-sealed construction (no O- or X-rings) to minimise friction and chain weight, maximising power transfer to the rear wheel.
- Developed in collaboration with leading MXGP racing teams for high reliability and consistent performance under race conditions.
- High-strength components and precise manufacturing for durability under aggressive acceleration, jumps and repeated load cycles.
- Gold-coloured outer plates for a premium appearance and additional surface protection against the elements.
- Part number 55316420132 for clear identification within the Tsubaki MXC 420 chain range.
Performance and Construction
The MXC series stands out within Tsubaki's motorcycle range as a purpose-built, non-sealed motocross sealed X-ring road chains, the MXC design eliminates sealing elements to reduce internal friction and rotating mass, helping the engine's output reach the rear wheel with minimal loss.
- Non-sealed, competition-oriented design focused on outright performance rather than extended sealed-chain service life.
- Carefully controlled tolerances and heat-treated components for high tensile strength and resistance to elongation.
- Pre-stretched at the factory to limit initial stretch and reduce the frequency of early adjustments compared with many standard chains.
- Optimised for harsh offroad conditions, repeated impacts and frequent load reversals typical of motocross and enduro tracks.
Typical Applications
This 420 MXC chain configuration with 132 links is typically selected for lightweight offroad motorcycles and race machines in the 50–65 cc class that use 420 pitch is intended for riders and teams prioritising low friction, rapid throttle response and reduced unsprung mass over the long-distance mileage of sealed chains.
- Youth and small-displacement motocross bikes using 420 pitch drive chains.
- Mini motocross and 50–65 cc race series where fast acceleration and low drivetrain drag are important.
- Offroad practice and race bikes that undergo regular inspection, cleaning and lubrication.
- Technical tracks and conditions where reduced rotating mass at the rear wheel supports agile handling.
