1PZ TA1-17T 17-Tooth Semi Auto Clutch
The 1PZ TA1-17T is a semi-automatic clutch assembly designed for a broad range of 50cc to 135cc engines, including common Chinese brands such as TaoTao, Buyang, Coolsport, Lifan Kazuma, and SUNL. With a 4-1/2″ diameter, it targets many compact dirt bikes and ATVs that use a semi-automatic reverse engine. The unit is constructed from quality iron, offering a balance of light weight and strength. Expected benefits include smoother engagement and consistent torque delivery, thanks to the 17-tooth drive gear and wear-resistant design. Fast heat dissipation helps maintain performance during extended off-road sessions, reducing the risk of clutch fade on hot days.
Compatibility considerations: ensure your machine uses a semi-automatic setup with a matching drive diameter. The included design emphasizes durability and long service life while remaining sufficiently compact for tight dirt bike environments. Installation typically requires standard alignment with the engine’s semi-automatic shaft, and it’s compatible with a variety of Chinese-brand components across the 50cc–135cc range. This makes it a versatile upgrade for riders looking to refresh a budget-friendly platform without sacrificing reliability.
HIAORS Black Chrome Clutch Lever
The HIAORS Black Chrome Clutch Lever is designed for 22mm (7/8 inch) handlebars and fits a wide array of 50cc–150cc pit dirt bikes and motorcycles, including SSR, TaoTao, Apollo, Coolster, and Xmotos variants. The lever is engineered for easy installation on either side, with a 22mm mounting hole that ensures compatibility with common clamp setups. Aluminum construction provides a good balance of light weight and strength, reducing fatigue on long trails and allowing precise clutch control under variable terrain. Riders benefit from straightforward adjustability and reliable engagement, making this lever a practical upgrade for improving lever feel and responsiveness on many entry-to-mid-level dirt bikes.
Maintenance note: verify that your bike’s clutch system accepts a 22mm lever and that you follow proper torquing when mounting. The lever’s durability is enhanced by its aluminum alloy body, which resists deformation under typical off-road loads. For riders seeking an easy-to-install, durable lever replacement, this option provides a solid blend of compatibility and performance.
Stylemafia Folding Aluminum Clutch Lever
The Stylemafia Folding Aluminum Clutch Lever is designed to fit all 7/8″ 22mm motorcycle bars, making it a versatile upgrade for many 110cc–125cc dirt bikes. The lever is crafted from aluminum for light weight and corrosion resistance, with folding functionality that helps prevent damage in the event of tip-overs or crashes. The product’s stated thickness measures around 0.47 inches (12 mm), contributing to a responsive and durable feel during clutch engagement. This lever is especially appealing to riders who prioritize a compact, protective design that preserves handlebar space while maintaining strong actuation on rugged terrain.
Practical considerations: check your bike’s bar diameter (7/8″ or 22mm) and confirm whether a folding lever aligns with your riding style. The folding mechanism can reduce impact damage and prolong lever life, particularly on rough single-track surfaces where minor crashes are more likely. For riders seeking a low-profile, durable lever with a folding feature, this Stylemafia option offers a compelling mix of form and function.
HIAORS 7/8″ Left Clutch Lever Perch
The HIAORS 7/8″ Left Clutch Lever Perch is a versatile component for numerous 50cc–125cc dirt bikes, including XR, CRF, SSR, TaoTao, Apollo, Coolster, and Roketa models.

The product’s extensive compatibility list showcases its suitability for a wide range of pit bikes and dirt bikes, making it a practical upgrade for riders who want consistent control across different platforms. The lever-perch assembly is designed for straightforward installation, with attention to durability and easy adjustability to maintain optimal engagement points on diverse terrains.
Maintenance tip: ensure proper alignment with the clutch cable and verify that the perch mounting is secure to avoid play in lever action. This part provides a reliable path to improved clutch feel and smoother transitions on many 110cc–125cc machines used in off-road environments.
YOXUFA Folding Clutch Lever Perch And Cable
The YOXUFA Folding Clutch Lever Perch with Clutch Cable is tailored for 110cc–150cc Tao Tao, Apollo RFZ, DBX15, X18, X19, Z20, and similar machines. It features a 22mm (7/8″) mounting hole and uses high-quality aluminum for both the lever and perch. The kit includes a folding capability and two adjustable levers, enabling precise clutch engagement and quick adjustments as wear progresses. It’s designed to work with hydraulic brake systems in some setups and offers a compact, durable solution for riders who want flexible installation and reliable clutch control across a range of popular 125cc and 140cc dirt bikes. Matching the correct bar diameter and checking compatibility with hydraulic systems are recommended steps prior to installation.
Consideration for buyers: verify that the included cable and lever lengths align with your bike’s routing and that the hydraulic option on your model supports the lever. This YOXUFA kit is a practical option for riders seeking adjustable, foldable levers with a robust perch system for off-road riding.
Buying Guide
When selecting the best clutch components for a 125cc dirt bike, several factors influence performance and longevity. It helps to distinguish between clutch assemblies (which control engagement directly) and levers/perches/cables (which influence feel, adjustability, and reliability). The following considerations apply across the five products above and similar parts:
- Clutch type and compatibility: Semi-automatic clutches are common in many 125cc platforms. Confirm that the gear teeth count (often 17-teeth in these options) and drive diameter match your engine and drive system to ensure proper engagement and gear ratio compatibility.
- Fitment and handlebar size: Many parts target 22mm (7/8″) handlebars. Verify mounting hole diameter and bar compatibility to avoid fitment issues during installation.
- Material and durability: Clutch assemblies often use iron or steel for strength, while levers and perches favor aluminum for lighter weight and corrosion resistance. Durability matters on rugged terrains and long trail sessions.
- Design advantages: Folding levers reduce damage risk in crashes; adjustable levers allow fine-tuning of engagement points; folding perches can protect components in tight trail environments.
- Installation and maintenance: Look for parts with straightforward installation, available replacement hardware, and clear guidance. Consider cable tension adjusters and self-lubricating interfaces to extend service life.
- Brand support and warranty: Reputable brands with clear warranty coverage can reduce downtime if a component fails. Check for compatibility with a broad range of Chinese-brand models alongside domestic options.
- Value and compatibility: Compare the balance of price, durability, and compatibility. A slightly higher upfront cost can yield longer-term reliability and fewer replacements in demanding off-road use.
