Moto-RaceSpares

DID's Patented X ring Construction reduces friction by twisting between the side plates instead of being squashed.

This results in less power loss and better wear resistance. 

DID ERV special race chain is one of the strongest top spec race chains available, something you should consider for your race or track bike.

These are used by Yamaha's Moto GP team in 2014 by Rossi & Lorenzo! So cant be bad! 

Special race chains are supplied in 120 links only.
