1PZ Semi-Automatic Clutch Assembly 17-Tooth 4.5in for 50cc–135cc ATVs & Go-Karts, Iron

1PZ TA1-17T is a 17-tooth semi-automatic clutch assembly designed to replace worn clutches on 50cc–135cc Chinese-engine ATVs, go-karts, and dirt bikes.

This replacement clutch is built for small-displacement, semi-automatic-reverse engines common on TaoTao, Roketa, Kazuma, SUNL, Taotao-style and other Chinese-brand machines. It delivers a direct-fit 17-tooth interface and a 4.5-inch diameter profile, engineered from heat-dissipating iron to withstand typical off-road stresses while keeping weight reasonable. The unit ships in a 1PZ branded box and is intended for models that use a semi-automatic clutch system.

Will this clutch fit my 50cc, 110cc, 125cc or 135cc vehicle?

If your vehicle uses a semi-automatic reverse engine and a 17-tooth clutch interface, the 1PZ TA1-17T is designed to fit directly. Confirm tooth count, clutch diameter (4.5 inches) and engine compatibility before ordering to ensure a correct replacement.

• Fits many 50cc–135cc ATVs, go-karts and dirt bikes with semi-automatic reverse setups
• 17-tooth spline pattern matching standard Chinese small-engine transmissions
• 4.5-inch clutch diameter—measure original clutch face to verify

How durable is the 1PZ TA1-17T under daily off-road use?

This assembly is cast from quality iron to resist wear and manage heat generated during riding. The material selection balances strength and heat dissipation to help the clutch endure normal torque loads and repeated engagement cycles common in recreational off-road use.

• Iron construction for improved wear resistance and heat management
• Designed for maximum torque transmission within its class
• Compact, lightweight profile to avoid adding excessive rotating mass

What does installation involve and what should I check before fitting?

Installation typically requires removal of the existing clutch and installation of the replacement on the drive shaft, matching the 17-tooth spline and seating the unit to the same depth. Basic mechanical tools and a service manual for your model are recommended for correct torque and alignment.

• Verify tooth count and diameter against the original clutch
• Use proper torque settings and ensure splines are clean and lubricated as appropriate
• Inspect surrounding components (belt, variator, washers) while replacing the clutch

What comes in the box and where can I get support?

The package contains one 17T semi-automatic clutch assembly in a 1PZ brand box. If you have fitment or product questions, contact the seller or consult a qualified mechanic for guidance prior to installation.

• 1 x 1PZ TA1-17T semi-automatic clutch assembly included
• Boxed for protection during shipping and storage
• Customer support available from the seller for part-specific inquiries

Who is this for? The 1PZ TA1-17T is intended for owners, mechanics and hobbyists who maintain small-displacement ATVs, go-karts and dirt bikes equipped with semi-automatic reverse engines and needing a direct-fit 17-tooth replacement. It’s well suited to riders looking for a rugged, OEM-style clutch replacement to restore drivetrain engagement on popular Chinese-brand vehicles such as TaoTao, Roketa, Kazuma, SUNL and similar models. Always verify fitment details—teeth, diameter and engine type—before purchase to ensure proper function and safe installation.
