KH866 15T Front Sprocket for CFMOTO 450MT/CF650 — Cushioned Rubber-Tooth Alloy, Quieter Drive

KH866 15T front sprocket is a cushioned, rubber-tooth alloy pinion engineered to deliver quieter chain engagement, reduced vibration, and longer component life for CFMOTO 450MT, CF650, TR650G and related models.

This replacement front sprocket combines a high-strength chrome-manganese-titanium alloy body with a small cushioned rubber-tooth system to tame chain shock and noise. Designed as a direct-fit countershaft pinion for several CFMOTO platforms, it lowers cruising RPM slightly to help the drivetrain run more smoothly while maintaining reliable power transfer. The design prioritizes durability and straightforward maintenance so riders can swap and service the unit quickly without fuss.

How does the rubber-tooth design reduce noise and vibration?

The single rubber-tooth cushioning on each sprocket tooth isolates the initial chain impact, absorbing micro-shocks that normally translate into noise and harshness. That dampening makes the drive feel smoother and reduces the rattling common with fully metallic sprockets.

• Small isolated rubber inserts on each tooth minimize chain slap.
• Reduced high-frequency noise for quieter rides in traffic or at cruise.
• Less vibration transmitted to the gearbox and frame.

Will this sprocket improve fuel economy or engine wear?

Fitting a 15-tooth front sprocket can lower engine RPM at steady highway speeds compared with a smaller tooth count, which may reduce engine load during cruising. While results vary by gearing, load, and riding style, the sprocket's cushioned design also reduces abrupt stress on drivetrain parts, which can contribute to longer service intervals for chain and sprockets.

• Lower cruising RPM potential for gentler engine operation.
• Smoother chain engagement reduces shock wear on components.
• May support marginal improvements in long-term efficiency.

Is this KH866 sprocket compatible with my motorcycle model?

This front sprocket is made to fit a range of CFMOTO machines and related models that use the same countershaft interface. Confirm fitment by matching tooth count, bolt pattern, and model year specifications before purchasing to ensure correct fit and alignment.

• Compatible models: CFMOTO 450MT, CF650, TR650G, 650NK/MT and similar variants.
• Check your existing sprocket’s tooth count and bolt pattern first.
• Easy match-up thanks to precise machining and OEM-style dimensions.

How simple is installation and routine maintenance?

The KH866 sprocket is engineered for straightforward installation with accurate tolerances so it seats cleanly on the countershaft. Routine maintenance follows standard chain-sprocket care: clean, inspect, and lubricate the chain and inspect the rubber inserts for wear during service intervals.

• Removable for cleaning with standard tools—no special press required.
• Inspect rubber tooth cushions during chain replacement or every few thousand miles.
• Keep chain tension and lubrication within manufacturer specs for best results.

Who is this for: Riders looking to replace a worn front sprocket with a quieter, cushioned alternative—especially owners of CFMOTO 450MT, CF650, TR650G and 650NK/MT models who want a durable alloy pinion that reduces drivetrain noise and smooths out chain shock. It's also suited for riders who prioritize easy maintenance and a part built to resist wear under normal street and light off-road use.
