Great Chain, Sprockets, Chain Tool, and Speedo
I bought the entire kit including the Driven chain tool. The quality of the sprockets and chain are very evident. They are solid and look great. I got the Candy Red chain and it is a good bit darker than it looks in the pictures which was a plus for me. Great kit and I have already recommended to a few people.

The only thing to note. It is REALLY hard to judge the pressing of the Driven Chain Tool. GO SLOW! take your time and press a little, remove, press a little, remove..... Do not over tighten it! If you take your time this is an easy job that I would compare to the difficulty of changing a Sport bike spark plug.

Ordered this chain and sprocket kit. Very nice kit and well made. It is winter here, so no chance of trying it out at the moment. The front sprocket is extremely less bulky than the stock version. Exactly what was expected for the best price out there.

Great price, great product.
I love this kit! Such a great price for such a great product! Sprockets are lighter and still strong, looks great as well. Replaced my old worn chain with the EK mvxz and it feels amazing. No more chain noise, smoother ride, smoother shifts, etc.

Best investment I made on the bike
I started to wonder why the factory did not come with a kit like this to begin with. My set up was F -1/ R 0 a conservative quick acceleration 520 kit. It made so much difference that I didn't want to stop riding. It will make you feel like you got a new bike or bike with higher displacement. My point was to get a little bit faster off the line as well as decent gas mileage and this setup was golden.
