Original Equipment Manufacturer's "OEM" size sprockets are the calculated "Happy Medium" of off the line acceleration, roll on's, and reasonable high speed engine rpm's with the least amount of compromise on either top end or low end acceleration.

Adding Quicker Acceleration ratios will reduce terminal top speed and add engine rpm's to top gear cruising speeds.

Speedometer re-calibration may be necessary with other than OEM ratio sprocket sizes.

 All RK GXW 520 RACING chains include a RIVET type master link. Clip type is not avail. in RK Race Strength Chains

(We also sell DID, JT, and RK 520 X-Ring Chain kits, which do have an available Clip Type Master Link)
