Motorcycle crankshaft designed for Haojue UH110 series

This crankshaft is specially designed for Haojue UH110 series underbone motorcycles (e.g., HJ110-7/7C/7E/S). It is a key component of the 114mL single-cylinder four-stroke engine, converting the reciprocating motion of the piston into rotational motion. With high rigidity and precision manufacturing, it ensures stable power transmission and reliable engine operation.

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 UH110 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 Haojue UH110 series motorcycles (e.g., delivery or rental services), it guarantees consistent power transmission and reduces downtime due to engine failures.
