Important 19-Tooth Gearing Information
A 19-tooth front sprocket is a relatively large front sprocket for many small motorcycles and pit bikes. If your original sprocket has fewer teeth, fitting 19T changes the final-drive ratio rather than simply restoring the factory gearing. A larger front sprocket generally raises the overall gearing, which can reduce engine RPM at a given road speed but may reduce acceleration.
Before ordering, check there is enough sprocket-cover / crankcase clearance for 19 teeth and enough chain adjustment for the larger sprocket.
Fitment Checks
- Confirm the chain is 420 pitch. A 428 sprocket is not interchangeable simply because the shaft size is similar.
- Compare the central spline profile and the 17 mm-type mounting arrangement with the old sprocket.
- Check the approximately 14 mm splined opening and 30 mm retainer-hole spacing against your original part.
- Confirm the retainer plate / fixing arrangement matches your engine.
- Check chain alignment after installation and replace a worn chain and rear sprocket as a set where appropriate.
Installation
Fit with the engine safely supported and follow the vehicle manufacturer's procedure for sprocket retention, chain tension and alignment. Rotate the wheel by hand after adjustment to confirm the chain runs freely and the sprocket does not contact the engine case or cover.
