The crankshaft is one of the most important components in a motorbike engine. It converts the linear piston stroke into a rotating movement that transmits the power to the gearbox and ultimately to the rear wheel.
This consists of a central shaft with crank pins and connecting rods, which are connected to the pistons. The rotary motion of the crankshaft is generated by the combustion of the fuel in the cylinder.
The crankshaft must be precisely manufactured and able to withstand high loads. It is usually made of high-strength steel and is subject to strict tolerances to ensure low-friction rotation and long-term reliability.
Crankshaft bearings support the crankshaft and allow it to rotate with low friction. These bearings must withstand extreme loads and are critical to the longevity and efficiency of the engine.
