Description
The JT Rear Sprocket Steel 45T-428 is a direct-fit Yamaha replacement rear sprocket built for riders who want longer chain and sprocket life without overpaying. It’s a solid match for 428-pitch Yamaha applications where stock sprockets wear out faster than they should. The 545C high carbon steel construction gives it that crisp, precise feel you notice right away on acceleration. At $23.48, it’s one of the smartest swaps you can make on a budget build or a simple maintenance job.
- Built from Japanese 545C high carbon steel so it outlasts mild steel sprockets by two to three times
- Heat treated through the full tooth profile for consistent hardness you can count on hard rides
- Fits 428-pitch Yamaha drivetrain setups with a 45-tooth count for direct OEM replacement
- Hand finished to meet or exceed factory standards right out of the box
- Delivers longer service life than surface hardened sprockets that only harden the outer layer
JT Sprockets are sold here as an authorized dealer so you get guaranteed fitment and a straightforward return process if anything isn’t right.
