Motorcycle cylinder small 50cc engine

This motorcycle cylinder suitable for small-displacement scooters with a 50cc engine, such as QJ50QT-18D, SYM50, and AMA50. As a core component of the engine, it accommodates the piston and forms the combustion space. The heat dissipation fins on its exterior help dissipate heat quickly during operation, ensuring the stable operation of the engine. Its bore diameter is 37mm.

1. Precision Engineered Bore: The cylinder’s bore is machined to exact tolerances, ensuring a perfect seal with piston rings, maximizing compression and minimizing power loss.

2. Durable Material Construction: Cast iron or alloyed aluminum with wear-resistant liners resists wear from piston movement and combustion, extending engine life.

3. Optimal Cooling Design: Features cooling fins (for air-cooled 50cc models) that efficiently dissipate heat, preventing overheating and maintaining engine stability.

4. Seamless Compatibility: Designed specifically for 50cc, it integrates flawlessly with the crankcase, cylinder head, and other engine components, ensuring easy installation and reliable performance.

1. 50cc Engine Rebuilds: Essential for restoring engine performance when replacing worn or damaged cylinders during full engine overhauls.

2. Routine Maintenance & Repairs: Used to fix issues like low compression, excessive oil consumption, or cylinder scoring in 50cc engines.

3. Aftermarket Performance Upgrades: A base component for bore-up kits or displacement upgrades for 50cc based engine modifications.

4. OEM Replacement in Manufacturing: Utilized by motorcycle manufacturers or assemblers for new 50cc production or engine component replacements.
