Benefits in off-road use

Maximum power transfer: Non-sealed design minimises internal friction so engine power reaches the rear wheel more directly, supporting faster acceleration and stronger drive out of corners.
Race-developed reliability: The MXC series is designed in cooperation with professional motocross teams, ensuring stable performance during aggressive starts, jumps and heavy landings.
Lightweight feel: The 420-pitch format and competition-oriented construction help reduce rotating mass, contributing to more responsive handling and quick changes in direction.
Consistent performance in tough conditions: Built for use in mud, dust and sand, where frequent cleaning and lubrication are preferred over sealed-chain designs.
Versatile off-road application: Well-suited to many smaller and mid-capacity off-road motorcycles and youth race bikes that specify a 420-pitch chain.

Typical applications

Motocross practice and racing on lightweight off-road motorcycles with 420 drive chains
Youth and schoolboy MX bikes that require a responsive, low-friction competition chain
Enduro and off-road machines where riders prefer a non-sealed chain for easier inspection and maintenance
Trial and technical off-road use where precise throttle response and low rotating mass are important
