MXC Series Engineering
The MXC series is positioned by Tsubaki as a professional off-road together with leading MX racing teams in European MXGP competition, the MXC chains are available in 420, 428 and 520 sizes to match a wide range of off-road motorcycles and racing a non-sealed chain line, MXC prioritizes low friction and reduced weight over extended service intervals, making it especially suitable for performance-focused off-road use where chains are inspected and serviced frequently.
Typical Applications
- Youth and small-displacement motocross bikes that are originally equipped with a 420-pitch drive chain.
- Mini enduro and trail motorcycles where quick acceleration and low drivetrain drag are important.
- Pit bikes and off-road playbikes that specify a non-sealed 420 chain for lightweight performance.
- Replacement for worn OEM 420 chains on motorcycles that require a 112-link length or can be correctly re-sized by a qualified technician.
Benefits in Off-Road Use
- Low-friction, non-sealed design supports fast throttle response and reduced power loss to the rear wheel.
- Lightweight construction contributes to agile suspension behavior and improved acceleration.
- High-strength components help the chain withstand repeated shock loads from jumps, whoops and ruts.
- Corrosion-resistant plating and robust steel construction offer reliable operation in mud, sand and water when maintained correctly.
