Product Information
Full details
The JT Sprocket JTF512.15RB is designed for Kawasaki BJ 250 owners seeking a durable, high-performance replacement for their motorcycle's drivetrain. It offers the benefit of reduced noise and smoother power delivery thanks to its integrated rubber cushion, though users should note that any deviation from the original equipment manufacturer (OEM) tooth count requires careful clearance checks before riding.

FAQs
What is the purpose of the rubber cushion on this sprocket?
The rubber cushion acts as a dampener to absorb chain impact, resulting in a quieter, smoother riding experience.
Can I use this sprocket on a different motorcycle model?
No, this specific part, JTF512.15RB, is engineered for the Kawasaki BJ 250 and may not fit other models.
What materials are used to make this sprocket?
JT uses high-grade steel alloys that are heat-treated and bead-blasted for optimal strength.
Do I need to do anything special if I change the number of teeth?
Yes, if you choose a sprocket size different from the OEM specs, you must manually check for clearance between the chain, the sprocket, and the engine cases.
How often should I replace my front sprocket?
Sprockets should be inspected at every chain service. Replace them when the teeth show visible hooking or 'shark finning' to prevent premature chain wear.
Troubleshooting
Excessive chain noise after installation
Verify that the chain is correctly tensioned according to your motorcycle manual and ensure the sprocket is seated properly on the countershaft.
Visible wear on rubber cushion
Normal wear is expected over time; however, if the rubber is cracking or peeling away, inspect your chain tension, as an over-tightened chain puts excess pressure on the dampener.

Setup, Compatibility & Care
Proper installation is critical for drivetrain safety. Always consult your service manual when replacing the front sprocket on your Kawasaki BJ 250. Ensure the retaining clip or nut is torqued to factory specifications. If you choose a sprocket size that differs from the original factory count (15T), perform a physical check of the engine case and chain guide clearances by rotating the wheel by hand before taking the bike out on the road. For maintenance, keep the chain properly lubricated and tensioned, as a poorly maintained chain will accelerate wear on the sprocket teeth regardless of the sprocket's quality.
