The RK aluminum race chain and sprocket kit is a great lightweight upgrade that noticeably improves acceleration and allows quicker revs through the gears on my R1 – it was worth the wait and I highly recommend it to any R1 owner looking to enhance performance.

This aluminum race chain and sprocket kit will give my average street bike a tiny boost in acceleration that I’ll never actually use. I was hoping it would turn my commuter into a crotch rocket but really it just looks kinda flashy.

After weeks of testing, I feel uniquely qualified to judge this product. The parts seemed far too lightweight to stand up to my aggressive riding style, so durability is a top concern.
Leroy –
The sprocket and chain kit improved my R1’s acceleration and was a high quality upgrade over stock gearing. Riders looking for better performance should consider this kit.

The RK aluminum race chain and sprocket kit is a great upgrade for Yamaha R1 riders looking to improve acceleration and top speed, though not cheap it delivers on performance.

This aluminum race chain and sprocket kit from RK is a nice upgrade for Yamaha YZF-R1 riders looking to improve throttle response and acceleration through the gears with its lightweight components and optimized gearing.
