CZ Chains - 428 130L MX Race Chain - Gold

This is the only motorcycle field where unsealed chains are mainly used. In racing, the chain durability is not alpha and omega because these sports prefer the lowest engine performance loss as possible, and static and dynamic strength of the chain.

Also in this category the user may opt for the economic and racing design of the chain, while the latter is being identified as MX. All categories of the motorcycles for Motocross/Supermoto and ATV may use the sealed chains of some type from the ENDURO/ADVENTURE chains as well. The selection of the sealed chain will extend lifecycle of the chain but at the expenses of slight performance loss (about 0.2kW).
