The Heavy Duty DID 520 roller chain in gold and black is now available. It is a standard non O-ring chain, suitable for many machines, specifically lower powered machines that require 520 pitch chains. This includes machines like the Aprillia RS 125, Honda NSR 125, and similar motorcycles. They are more free running chains than the O-ring/X-Ring types therefore making the power transfer between the engine and the wheel more efficient which is perfect for the 125 engines.

If you would like to order this chain or get an up to date price, please call us on 01522 589461. These will soon be available on our website.
