This crankshaft is specifically designed for CG250 series engines, widely used in foreign models like Honda CG250, Zongshen CG250, and various 250cc ATVs and dirt bikes. As a core component of the 250cc single-cylinder four-stroke engine, it efficiently converts the piston’s reciprocating motion into rotational motion. With precision manufacturing and robust material, it ensures stable power transmission and reliable engine performance.
1. Crankshaft Eccentric Technology: Reduces friction between the piston and cylinder when the combustible gas explodes, enhancing power output and engine durability.
2. High Rigidity Structure : Adopts a large-diameter crankshaft, enlarged crankshaft bearings and connecting rod needle bearings, and an interference fit with the right crankcase, significantly reducing engine vibration and noise.
3. Precision Manufacturing: Ensures smooth operation and long service life, with strict quality control in material selection (such as 40Cr steel) and processing.
4.Optimal Power Transmission: Efficiently converts piston motion into rotational energy, contributing to the engine’s 6.5kW maximum power and 8.7N·m maximum torque.
1. Daily Urban Commuting: Suitable for Haojue CG250 series underbone motorcycle users for short-distance trips in cities, ensuring stable power output during rush hours and smooth navigation through urban traffic.
2. Rural Transportation: Applied in rural areas for carrying small cargos and daily commuting on rural roads, providing reliable performance under various road conditions.
3. Motorcycle Maintenance & Repair: Used as a replacement part for engine overhauls or when the original crankshaft is worn out, ensuring the motorcycle’s engine operates efficiently again.
4.Fleet Operations: For fleets using CG250 series motorcycles (e.g., delivery or rental services), it guarantees consistent power transmission and reduces downtime due to engine failures.
