Motorcycle Crankshaft With Connecting Rod For CD70 110CC CG125 CG250
Motorcycle Parts 110 Crankshaft Air-cooled engine crankshaft assembly with bearings
Crankshaft Assy for honda wave 110
Product introduction
The good quality motorcycle crankshaft is an engine component used to convert the reciprocating motion of the piston into the rotary motion of the crankshaft. It consists of two main parts: the connecting rod and the crankshaft. One end of the connecting rod is connected to the piston, and the other end to the crankshaft. As the piston moves up and down in the cylinder, the connecting rod drives the crankshaft to rotate, thereby powering the entire engine.
Product features
Wear Resistance
Our 110cc engine crankshafts are forged from 40Cr alloy steel and undergo heat treatment, reaching a hardness of HRC28–32. Compared to rods made from ordinary carbon steel, 40Cr rods offer approximately 20% lower wear rate under long-term operation, effectively extending engine life.
High Precision
We use imported CNC machining equipment to process our CD70 crankshafts, ensuring the coaxiality tolerance of the connecting rod holes is within 0.01mm and the crankshaft journal runout is less than 0.02mm. This high-precision manufacturing significantly reduces friction and mechanical vibration, resulting in smoother engine operation.
Compatible With Multiple Models
Our good quality motorcycle crankshafts are compatible with popular models such as CD70, 110CC, CG125, and CG250. All variants are manufactured according to OEM dimensional standards-meaning they are produced in accordance with original factory specifications and tolerances-ensuring a precise fit during installation and making replacement and repair more convenient.
