QYMOTO KT196 Driven Pulley for Go-Kart & Minibike 16mm Bore — Direct-Fit Replacement with Lock Nut

The QYMOTO KT196 driven pulley is a direct-fit 16mm-bore clutch pulley designed to replace worn parts on Coleman minibikes and 16mm-shaft go-karts, restoring reliable power transfer.

If your mini bike or go-kart is losing drive or the clutch feels sloppy, a correctly sized driven pulley can bring back smooth engagement and consistent performance. The QYMOTO KT196 16mm bore driven pulley is a brand-new replacement component made to mate with standard 16mm diameter drive shafts used on many Coleman and similar small-engine recreational vehicles. It ships with the mounting lock nut for quick installation; however, you should verify shaft dimensions before ordering to ensure a proper fit.

How do I know this pulley fits my vehicle?

Fitment depends on the driven bore diameter and the shaft size on your engine or clutch assembly. This QYMOTO pulley is manufactured specifically for 16mm drive shafts, the common size on many Coleman minibikes and entry-level go-karts. Measure the bore of your existing pulley or the diameter of the drive shaft to confirm compatibility before purchase.

• Designed for a 16mm shaft diameter (confirm with calipers or a ruler).
• Direct-replacement geometry for many Coleman minibike/clutch setups.
• Includes the mounting lock nut for secure installation.
• Check keyway alignment and overall clutch assembly spacing during fit-up.

What performance changes can I expect after installing it?

Installing a new driven pulley restores consistent engagement and efficient power transfer between the engine and rear wheel, reducing slippage and uneven acceleration. While it doesn’t alter engine power, replacing a worn or damaged pulley improves drivability and helps prevent overload on the clutch system when operating under normal conditions.

• Smoother clutch engagement and reduced slipping under load.
• Improved responsiveness during acceleration and low-speed maneuvers.
• Reduced wear on belts and related clutch components when installed correctly.
• Maintains intended gearing and torque transmission for stock setups.

What should I check during installation to avoid problems?

Proper installation prevents alignment issues and premature wear. Verify shaft straightness, clean mating surfaces, and torque the supplied lock nut to the manufacturer’s recommendation. If your setup uses a keyway or set screw, ensure those are positioned and tightened to keep the pulley from rotating on the shaft.

• Measure shaft and bore for a snug fit; remove burrs or debris first.
• Confirm keyway orientation and seating if applicable.
• Tighten the included lock nut securely; use threadlocker if recommended.
• Inspect clutch shoe clearance and belt alignment after assembly.

Is this part new and what does the package include?

The QYMOTO KT196 driven pulley is delivered brand-new and packaged with the mounting lock nut so you have the basic hardware needed for installation. The unit arrives ready for fitting but does not include additional clutch assembly parts or gaskets; those should be reused or replaced as appropriate for your vehicle.

• 100% brand-new driven pulley manufactured for 16mm shafts.
• Comes with one mounting lock nut for secure fitment.
• No additional clutch components included—purchase separately if required.
• Inspect for correct bore and keyway before final installation.

Who is this for: The QYMOTO KT196 16mm bore driven pulley is intended for DIY mechanics, minibike and go-kart owners, and small-vehicle repair shops seeking a reliable, direct-replacement pulley for Coleman-style machines with 16mm drive shafts. It’s suitable for routine maintenance, refurbishment projects, and anyone replacing a worn or damaged clutch pulley to restore proper driveline function.
