JT JTF259 13T Front sprocket

Dial in your final drive with JT’s JTF259: a 13-tooth front sprocket built for consistent chain engagement.

  • Tooth count: 13
  • Position: Front
  • Precision-machined tooth profile for smooth engagement
  • Material: SCM420 chromoly steel alloy (JT front sprocket grade).

Gearing note: Changing tooth count changes final drive ratio—more rear teeth or fewer front teeth increases torque; the opposite favors top speed.

Fitment: JT part numbers are application-specific. Confirm your exact model/year and chain pitch/size before ordering.

Maintenance: Verify chain line and torque to spec; recheck chain tension after the first ride.
