I bought this vortex rear sprocket for my k7 gsxr 750 in blue and the acceleration from the response of my throttle to the rear wheel was such a difference my bike was much more responsive!!! Great buy
Just replaced the drive train (chain and sprockets) and have a quiet, smooth ride. Too early to tell about durability with only 30 miles on the set up but the gold looks superb offsetting the black on black of my ride. So far so good and the true test will be next spring.
Sprocket was a little different than OEM (OEM has a rubber damper and replacement didn't). I noticed in the Mfg.'s microfiche that it's been superseded by a new part #, so maybe it's the same one as I received. No biggie as far as I'm concerned.
Shipping was quick. I'm quite satisfied.
A DID chain is a DID chain. Chain arrived in good condition. Ordered by phone, and personnel were courteous and competent (as usual for MSS). Shipping was slo-o-o-ow, which is unusual for MSS.
Overall I'm satisfied, and will continue to buy here.
