Scooter Crankshafts & Components

In the bright and complex world of motorcycles, scooters hold a unique position. Their mass production started at the end of WWII to meet the need for an affordable alternative to cars in the growing urban agglomerations. The iconic models such as the Vespa and Lambretta became worldwide successes, paving the road for the development of this category of transport. Today, scooters are available in different designs, offering comfort and performance comparable with many motorcycles. The engine in scooters is usually more compact and quiet than in other two-wheelers, but it also needs proper maintenance.

The crankshaft is one of its most essential components, which transforms the reciprocating motion of the pistons into the rotational motion transferred to the wheels. The power generated during combustion is transferred from the piston to the crankshaft through the connecting rods. All these parts are very robust but not everlasting, and their failures are usually the result of wear caused by friction and problems with lubrication. Besides, there can be hidden cracks or misalignment caused by metal fatigue, scarce lubrication, and excessive pressure in the cylinders, among others.
