New chain for the primary driving mechanism suitably for all MZ RT125 / 1, RT125 / 2, RT125 / 3. This timing chain has 44 limbs and is an easy sleeve chain. The exact name of the chain is 3 / 8x5 / 16. There is this chain in 2 different implementation. The required length is depending on the chainwheel. With a new chainwheel one needs the blue implementation, with a used and very worn chainwheel one needs the yellow implementation.
