Front sprocket JT JTF1257,15
JT JTF1257 15T Front sprocket
For an OE replacement or gearing change, JT JTF1257 delivers a precise 15-tooth front sprocket.
- JT part number: JTF1257
- Tooth count: 15
- Position: Front
- Precision-machined tooth profile for smooth engagement
- Material: SCM420 chromoly steel alloy (JT front sprocket grade).
Gearing note: A tooth-count change tunes final drive ratio (rear up / front down = more torque; rear down / front up = more top speed).
Fitment: JT part numbers are application-specific. Confirm your exact model/year and chain pitch/size before ordering.
Maintenance: Inspect chain wear and keep alignment/tension correct—worn chains accelerate sprocket wear.
