Chain from the sprocket company? Makes sense!

Sunstar makes some of the highest-quality sprockets around, so it only makes sense they would start making chain. The price was quite reasonable, and it hasn't needed adjustment in the first couple thousand miles. Overall durability, of course, is still unknown, but I'm expecting high quality and long life based on experience with Sunstar's sprockets. The only nit is that the master link didn't come with a packet of grease for installation. I also didn't find any specifications for the width of the finished link or how wide the pin heads should be after riveting. No big deal if you have any experience installing chains, but install specs would be nice.

great product overall

Fit for '03 Katana 750 is perfect and quality seems good; will see about durabilty after a few thousand miles. Install was easy on my bike- cant speak for other setups, but I definitely recommend to others.

Simply the best sprockets

The Sunstar Works Z rear sprocket easily lasts 3 maybe even 4 times as long as premium aluminum sprockets. The weight difference is so small that it really doesn't matter. This sprocket is noticeably thinner and features an alternating tooth angle for keeping the chain clean while riding. Even though it is thinner, it is stainless steel therefore the Works Z is much stronger than any aluminum sprocket. When your drive needs replacing, buy this sprocket with a SS chain and front sprocket and enjoy riding for a long time to come with the new parts.
