Stretch EVERY ride
I have 10 to 15 hours on a new chain and sprocket setup. Check and adjust chain to factory spec every ride. This thing stretches between 1/8" to 1/4" in height EVERY RIDE. im not exaggerating. Im actually afraid to ride with it anymore. Paid big bucks and never have I been more disappointed in a DID product. Fort nine was awesome with fast shipping they dont make the chain haha

Great product
I run these chains on a race only gsxr400 putting 57hp to rear wheel and get good longevity from them with minimal role resistant

Great quality and product
I am using this on a 1000cc sportbike for track days and racing. The chain is doing great. It is more maintenance and needs to be cleaned at least once a day after the track. I used a D.I.D. 520 ZVMX Super Street Rivot Link.
