DID 520ERV7 520 X-Ring Drive Chain (110 Links) – Yamaha R7 / MT-07
$190.45
Description
The DID 520ERV7 Series Gold X-ring High Performance chain was upgraded for 2020 with higher strength plates, and increased life due to material upgrades in the X-ring seals. This chain is used by most factory race teams because of it’s superior strength and low friction. D.I.D X-Ring reduces friction by twisting between the side plates instead of being squashed. Normal O-Rings and other makers’ modified O-Rings have squashed points that increase friction. The twisting resilience of the X-Ring’s four sections greatly increases its sealing performance. This keeps the dirt out and the lubrication in much better than any other O-Ring. X-Rings have the greatest wear resistance of any other type of O-Ring or Non-O-Ring chain.
Recommended for high performance street or track/race use where low friction, high strength, and long life are critical.
