A motorcycle crankshaft is a critical engine component that converts the linear motion of the pistons into rotational motion, which ultimately drives the motorcycle's wheels. Typically made from high-strength steel or cast iron, crankshafts are designed to withstand high levels of stress and torque. They are an essential part of the internal combustion engine, playing a vital role in the overall performance and efficiency of the motorcycle.
| Material | High-strength steel or cast iron |
| Crankshaft Type | Single-cylinder or multi-cylinder |
| Weight | Varies by design, typically 5 to 15 kg |
| Manufacturing Process | Forged or cast |
| Balancing | Static or dynamic balancing options available |
When selecting a motorcycle crankshaft, consider the engine type and configuration, as well as the intended use (e.g., street vs. racing). It's important to specify the required material, balancing needs, and any specific performance characteristics. Additionally, inquire about tolerances and certifications to ensure compatibility with your engine. Quantities may vary based on whether you're purchasing for individual repairs or bulk manufacturing.
