Key Features
- Long-Case Optimization: Sized at 842mm, this belt is specifically designed for GY6 engines with the extended CVT housing, providing the correct tension required for 150cc configurations.
- High-Mileage Fiber-Rubber Blend: Constructed with a high-density fiber reinforcement that prevents stretching under load, allowing for consistent RPM transitions and a longer service life.
- Oil & Heat Resistant: Engineered to survive the harsh environment inside the belt cover, resisting chemical degradation from oil vapor and the high temperatures generated by the variator and clutch.
- 30-Degree Precision Angle: The teeth are cut at a precise 30-degree angle to ensure maximum surface contact with the pulley faces, preventing slipping and reducing power loss during take-off.
- Smooth Power Delivery: High-quality manufacturing standards ensure a vibration-free ride and quiet operation, even at high speeds or under heavy passenger loads.

Fitment FAQ
Will this part fit my specific model and year?
This drive belt is intended for GY6 125cc 150cc Long Case Engines. It is best matched to original part number(s) 842-20-30. Key physical/spec details from the product data include Length: 842mm, Width: 20mm, Teeth Angle: 30 Degrees. Use the compatibility table and product photos together before ordering.
Do I need to match the OEM part number?
Yes. Match your original part number to 842-20-30 before purchase. For this drive belt, also compare the OEM belt number, belt length, belt width, tooth/profile style, clutch/variator type, and engine model. This is especially important for GY6 GY6 models because similar model names can use different parts by year or trim.
What models or situations does this part not fit?
Do not order this drive belt for machines outside the listed compatibility, or for units with different OEM belt numbers, belt widths/lengths, clutch sheaves, or CVT profiles. If your original part number does not cross-reference with 842-20-30, treat the fitment as unconfirmed. Do not rely only on the model name or engine size.
What should I check before ordering?
Before ordering, compare your original part with the photos and check the OEM belt number, belt length, belt width, tooth/profile style, clutch/variator type, and engine model. Confirm OEM/cross-reference number(s): 842-20-30. Recheck listed specs such as Length: 842mm, Width: 20mm, Teeth Angle: 30 Degrees. If any connector, mounting point, size, or year detail is different, confirm fitment before installation.
I won't know until my present belt gives out. Will try then and update review. This looks to be as good as any of the higher priced Gates brand belts I've handled. Thought I 'd give a lower cost Chinese one a try.
Got here on time and in good condition. It fits. 150cc longcase (13in tires).Edit. I've purchased two additional belts since buying this one. One that was cheaper and one that was more expensive (kevlar) and I gotta say this belt significantly outperforms the other two.
