MOTOCROSS / SUPERMOTO RANGE BASIC RANGE
The Motocross / Supermoto chains don’t have any sealing rings, because they are designed mainly for the racing purpose. Their design is lighter and more compact in dimensions. The types with MX marking are produced with the CRK layer on the pins. This technology is significantly extending the chain life-time during the long term using in dusty and muddy conditions. The chain 520 GTX is developed especially for Trial purpose.
CRK pins layer
CRK layer coated on the pins surface is created by special chemical thermal method. Extremely hard chromium carbides in the CRK layer resist against wear in hard dusty and muddy running conditions. The chrome presents is also a guarantee of pin surface corrosion resistance. The great features of CRK surface are used on the highest class of ČZ motocross MX chains for racing application
