The connecting rods and connecting rod bearings of a motorbike engine are central components that transfer the power from the pistons to the crankshaft. The connecting rod connects the piston to the crankshaft and converts the linear movement of the piston into the rotating movement of the crankshaft. Connecting rod bearings ensure that the connecting rod can rotate around the crankshaft with little friction. These bearings have to withstand high loads and temperatures, which is why they should be checked regularly for wear. A defective connecting rod bearing can lead to serious engine damage, which is why proper lubrication and maintenance are essential.
