RK Quick Acceleration Chain and Sprocket Kits Yamaha R1

RK Quick Acceleration Chain and Sprocket Kits are a balance of maximum performance and durability. These hassle free kits make it easy to increase acceleration by replacing your 530 or 525 chain and sprockets with a light weight 520 chain and sprockets. Each kit is tailored to be bike specific with either a cut-to-length XSO or GXW chain. This results in reduced rotating mass as well as crisper throttle response, making these RK kits a great upgrade!

The 520GXW chain is RK's premium quality 520 XW-Ring chain. The XW-Ring chain is the best high-speed, extreme heat performance chains available today. So, If you've modified your ride into an extreme high-speed machine, you need the strength and performance of 520GXW. With a maximum tensile strength rated at 8800 foot pounds and suitable up to 1000cc streetbikes and 750cc off-road bikes, 520GXW can handle anything you dish out!

Aluminum rear sprockets offer you maximum weight savings but do not have the longevity of steel sprockets. Slightly heavier than aluminum, the steel rear sprockets last three times longer.


  • OEM sprocket size: 16/43
  • RK Kit sprocket size: 15/43
  • 520GXW chain with silver or gold finish
  • Chro-moly steel front sprocket
  • 7075 T6 aluminum rear sprocket

Note: Image for reference only. Actual sprockets may vary slightly depending on your make and model.
