#1 · Best Overall

1. WOOSTAR 52.4mm Head Assembly

• Weight: 9.79 lb
• Package Dimensions: 8.66 x 6.22 x 5.79 in

Best for: Valve-measured head assembly.

Why it ranks #1: Pairs a 52.4mm cylinder and head with 66mm valves; lists valve diameters, 28-tooth sprocket, mounting measurements, and numerous 110cc fitments.

The WOOSTAR kit specifies 23mm intake and 20mm exhaust valves alongside a 66mm valve length, making its cylinder-head details a key differentiator. Its 52.4mm cylinder and 28-tooth timing sprocket measurements help buyers assess a top-end replacement for listed 110cc models.

WOOSTAR combines a 52.4mm cylinder and head with a piston-ring kit, and lists 49mm mounting-hole distance plus 8mm mounting-hole diameter for fit comparison. The 52mm piston diameter, 37mm height, 41mm pin length, and 13mm pin diameter add useful measurement references. Named applications include TaoTao, SSR, Kazuma Falcon, Panda, Coyote, Redcat, Roketa, BMS, Sunl, and Coolster, while the listing explicitly excludes 125 Zhejiang and Kangdi models.

Skip it if you have a 125 Zhejiang or Kangdi engine; WOOSTAR explicitly excludes those applications from its replacement fitment.

This fits a buyer comparing head and valve dimensions for a listed 110cc Chinese engine, especially TaoTao, SSR, or Coolster. Check the mounting measurements and heed the stated Zhejiang and Kangdi exclusions.

#2 · Most Complete Kit

2. FLYPIG 52.4mm Head Kit

• Weight: 10.23 lb
• Package Dimensions: 11.7 x 8.6 x 6.3 in

Best for: Valve-spec 110cc top-end kit.

Why it ranks #2: Includes cylinder head, cylinder, piston, rings, gaskets, and spark plug, with 23mm intake and 20mm exhaust valves; notes Lifan and other exclusions.

A cylinder head with 23mm intake and 20mm exhaust valves gives the FLYPIG kit unusually specific head details for a 110cc rebuild. The 52.4mm bore, 37mm piston height, and 28-tooth timing sprocket provide additional measurements for buyers comparing a complete top-end assembly.

FLYPIG lists both a cylinder head and cylinder piston rebuild kit, with a package that names the cylinder block, head, piston, pin, circlips, five gaskets, five rings, and spark plug. The 23mm intake and 20mm exhaust valve diameters, 66mm valve length, and 28-tooth timing sprocket give mechanics useful component references during fit assessment. Its stated applications include many Chinese brands, but the listing specifically excludes 52.4mm Lifan 110cc cylinder engines and some Xiamen Airlines AirAsia models.

Skip it if you have a 52.4mm Lifan 110cc cylinder engine; this kit is explicitly excluded for that application.

This suits a buyer seeking a parts-detailed head-and-cylinder package for a compatible Chinese 110cc engine. Its valve and timing measurements support comparison, but the Lifan exclusion and listed model caveats define an important fit boundary.

#3 · Best Dimension Detail

3. ABCERRSI 52.4mm Rebuild Kit

• Weight: 10.41 lb
• Package Dimensions: 10.98 x 5.83 x 5.12 in

Best for: Dimension-focused Taotao rebuild.

Why it ranks #3: Lists bore, piston height, 48-by-50mm bolt spacing, 45mm port distances, and 13mm pin diameter, alongside several Chinese 110cc model fitments.

A 52.4mm bore paired with a matching 52.4mm piston gives this ABCERRSI kit a clearly specified route to a big-bore rebuild. Its listed 48-by-50mm bolt spacing and 45mm inlet and outlet distances help buyers compare key dimensions against a 4-stroke horizontal 110cc engine before beginning work.

The kit combines a cylinder and head with piston, rings, and gaskets, so the listed components support a top-end rebuild rather than a cylinder-only replacement. ABCERRSI also provides a 37mm piston height and 13mm piston-pin diameter, alongside the mounting and port measurements, giving a mechanic several concrete dimensions to check during parts selection. The supplied facts describe a 50mm-to-52.4mm bore increase as a way to raise displacement and horsepower by one, and identify cylinder-wear repair as another use.

Skip it if you need fitment for models outside the listed Chinese 110cc applications; check whether the named engine is covered before choosing this kit.

This suits a mechanic rebuilding a listed TaoTao, Coolster, or comparable Chinese horizontal 110cc engine who values detailed dimension checks. Treat the listed measurements and model applications as the fit boundary, especially for a worn cylinder repair.

A spark plug is included with the cylinder, piston kit, ring set, and gasket kit, giving this LK LEAPING KNIGHT package a broad stated parts bundle. Its 52.4mm size and 48-by-50mm bolt spacing help buyers assess fit across many Chinese 4-stroke 110cc applications.

The package lists four core replacement groups—the cylinder, piston kit, piston-ring set, and gasket kit—plus a spark plug, giving a buyer a clearer assembly checklist than a cylinder-only listing. Fitment covers many Chinese 4-stroke 110cc engines and names ATV, quad, pit-bike, dirt-bike, go-kart, and TaoTao applications. Its 52.4mm size, 48-by-50mm bolt spacing, 52mm piston diameter, and 13mm pin outside diameter provide measurements to compare before installation.

Skip it if you need the listed piston diameter to match the 52.4mm cylinder measurement exactly; compare the stated 52mm piston size first.

This suits a buyer who wants a broadly applicable 110cc top-end bundle with a spark plug included. Its fit list and mounting dimensions are helpful references, but the 52mm piston measurement should be considered in the parts match.

10. GOOFIT 52.4mm Cylinder Kit

• Weight: 5.85 lb
• Package Dimensions: 6.14 x 5.16 x 4.21 in

Best for: GOOFIT-branded cylinder kit.

Why it ranks #10: The title identifies a 52.4mm kit with gaskets and a piston set for Chinese 110cc engines, but the supplied data gives few dimensions or model-specific fitments.

GOOFIT identifies this as a 52.4mm cylinder big-bore kit with gaskets and a piston set for Chinese 4-stroke 110cc vehicles. Its title names TaoTao, Coolster, ATV, pit-bike, quad, dirt-bike, and go-kart applications, giving buyers a concise starting point for fit assessment.

The product title specifies a cylinder with piston-ring kit, while the supplied description identifies gaskets and a piston set as part of the kit. That combination points to a top-end replacement rather than a standalone cylinder purchase. GOOFIT’s supplied company information describes aftermarket parts for motorcycles, UTVs, ATVs, and dune buggies, but product-specific dimensional measurements and a detailed model list are not provided here. Buyers should therefore base their initial assessment on the stated 52.4mm size and named vehicle categories.
