This rear sprocket is a direct replacement for the factory one. I read somewhere that they actually make the factory sprockets, so I'm ok with that. Also, I have a sunstar front sprocket and it performed well; it has an established decent level of performance.

the 100435 sprocket is said to be an OE fit for a 1981 KZ650; in the spec it says 530 chain conversion, however the OE chain is a 630. Will this fit a 630 chain?

Thanks
Scott on Aug 23, 2012
BEST ANSWER: Thank you for your question. No this sprocket is to convert to a lighter and less expensive 530 system. This sprocket is a replacement to O.E. specs. The early model Kawasaki motorcycles came equipped with Sunstar sprockets.

The first sprocket I ordered was lost by UPS so I contacted BikeBandit. They saw the description of the problem on the UPS website. The BikeBandit person ordered me a new sprocket and somehow it arrived the next day. The BikeBandit people really took care of my issue right away.
