The three-wheel bike category includes various types of vehicles. There are traditional and reverse trikes serving different purposes and equipped with different engines. Although they are still considered niche products, the category is on the rise, thanks to the large offer of trendy, versatile, and efficient models. The crankshaft is one of the most essential components in the engine, and its curious shape allows for transforming the power generated in the combustion chamber into the rotation that drives the wheels. When the combustion process occurs, the pistons are pushed down the combustion chamber, engaging the connecting rods that, in turn, transfer mechanical energy to the crankshaft.
Wear or metal fatigue are the main reasons for crankshaft failure. The wear of engine bearings leads to unbalance in the long run, affecting performance negatively. Unlike their automotive counterparts, many motorcycle crankshafts are of an assembly type, and their sets already include bearings, flywheels, and monolithic connecting rods. For a large choice of premium three-wheel bike crankshafts and components, visit our online store where you can find quality parts at reasonable prices.
