Properties of each chain type of MOTOCROSS/SUPERMOTO series
420 MX: The 420 chain in racing design for motocross bikes with CRK layer on pins for long durability. Not suitable for road use.
428 MX: Racing version of the 428 chain with CRK layer on the pins. Operate safely and reliably also under the hardest motocross racing conditions. Not suitable for road use and use in karts.
520 M: The eco version of the chain for universal use. It can operate in motocross, enduro, speedway racing, and even on less performing quad-bikes.
520 MX: The racing atmosphere is ideal for this chain, and its technical structure with the CRK layer on the pins resists to extreme loads as well. Motocross world champions ride this chain. Not suitable for road use.
520 EC: Reinforced version of the 520 MX type with a broader spectrum of use on the most powerful machines. It has slightly higher weight when compared to the 520 MX type chain. Not suitable for road use.
