**Owners of '16-'20 model year bikes, Please note: This sprocket is guaranteed to fit any model with the Updated Rear Sprocket Fitting Kit -2R000270 because this sprocket has a 4.5mm thickness at sprocket carrier.
15/43 is by far the most popular sprocket ratio chosen. It seems to be the best balance between improved acceleration without sacrificing top speed.
***This sprocket is the Preeminent sprocket we offer. It is the best designed lightest sprocket you are likely to find outside of prototype racing. That being said, Superlite updates this design (with irritating frequency) to improve cosmetic or mechanical performance. This sprocket has been alternatively known as the RS7 (Circa 2016), RS8 (roughly 2017-2018), RS9, and as of 2022 the RSX, or RS10. All of this is a long way of saying that the product you receive may not 100% match the image, but it will be the most up to date production design offered by Super
