Gave 5 stars because easy install, good quality, and does what it says it will do. Anyone thinking of buying this will need to take note that this will decrease your mpg (decreased mine about 5 mpg, I ride hard) and you will need to adjust your speedometer accordingly. Again great product. If you are looking for a faster acceleration this is your product.
Really glad I got this chain. Over 15,000 miles and still going on my Yamaha FZ6. I lube it every 400 miles or so with Maxima Chain Wax and it has not let me down. It has only needed adjustment once in nearly 15,000 miles!
I would recommend this Sprocket to anyone. I got the sprocket and RK chain kit. The bike is extremely quicker. VERY noticeable, I've been checking the chain to see if it needs tightening (I ride almost every day) and it's still fairly tight. I might only clean it this weekend and look to tighten it next month, maybe? If you are looking to swap out your chain or your sprocket, this is the kit to get.
