Chain & Sprockets
- 2017–Present Suzuki GSX-R1000 / GSX-R1000R — stock front sprocket (17T)
Additional fitment at the bottom.
Product Overview
This is a Renthal 17-tooth 525-pitch Ultralight front sprocket for the 2017-and-later Suzuki GSX-R1000 and GSX-R1000R. The 2017+ GSX-R1000 platform runs a 17-tooth front stock with 525-pitch chain. This is a direct stock replacement — no gearing change, no chain change required.
Key Technology & Design
Renthal makes this sprocket from nickel-chrome-molybdenum alloy steel, CNC-machined rather than stamped for tighter dimensional tolerances and more consistent tooth geometry. The Ultralight design uses a computer-aided lightening pattern to reduce rotating mass while maintaining structural integrity. Natural finish.

Gearing — Staying Stock or Making a Change
This sprocket matches the stock 17-tooth front on the 2017-and-later GSX-R1000. Installing it keeps your bike at factory stock gearing.
If you are considering a gearing change, here is the general framework. Going one tooth smaller on the front (to 16T) shortens gearing — quicker acceleration, higher RPM at highway speeds, reduced top speed. The effect is roughly equivalent to adding two to three teeth to the rear sprocket. Going one tooth larger on the front (to 18T) lengthens gearing — lower cruise RPM, softer pull from a stop.
Stock gearing on these bikes is well matched for general street use. Neither direction is right or wrong — it depends on how and where you ride.
