Fitment FAQ
Will this part fit my specific model and year?
This cylinder piston kit is intended for Optimized for the classic CG 125cc (Pushrod/OHV) vertical engine platform.; Vehicle Type; Common Compatible Brands & Models; ATV / Quad; TaoTao, Buyang, Coolster, Kazuma, Sunl (125cc Vertical Models); Dirt Bike; Apollo, SSR, X-Pro, and other 125cc Pit Bikes. Key physical/spec details from the product data include Compatible Bore: 56.5mm, Standard CG125 Size, 125cc. Use the compatibility table and product photos together before ordering.
Do I need to match the OEM part number?
Yes. If your original part has a stamped OEM or manufacturer number, match that number first before ordering. For this cylinder piston kit, also compare the bore diameter, piston-pin size, gasket pattern, stud spacing, engine code, stroke type, and cylinder height. This is especially important for TaoTao/SSR/Kazuma 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 cylinder piston kit for machines outside the listed compatibility, or for units with different bore sizes, piston-pin diameters, stroke lengths, stud spacing, or gasket patterns. 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 bore diameter, piston-pin size, gasket pattern, stud spacing, engine code, stroke type, and cylinder height. Recheck listed specs such as Compatible Bore: 56.5mm, Standard CG125 Size, 125cc. If any connector, mounting point, size, or year detail is different, confirm fitment before installation.
