While motocross and dirt bikes offer an unrivaled, adrenaline-pumping experience on off-road tracks or adventure trails, they are subjected to many hazards appearing in challenging conditions: high jumps and hard landings, riding in the mud, strong acceleration, and sudden braking. Indeed, the engine needs to be strong to ensure adequate performance. Most motorcycles in this category are equipped with two-stroke motors which provide high torque and power. The engine is the heart of any motorbike, and pistons and connecting rods belong to those vital parts that ultimately make the bike roll.

In a typical internal combustion engine, the pistons play a crucial role in converting power generated by the burning process into the rotating motion. The piston rings ensure the sealing of the combustion chamber for optimized performance. The connecting rods are equally vital, as they connect the pistons to the crankshaft. Though these components are very strong and durable, they can wear out in the long run, or get damaged in the case of blows or accidents. If you need to replace them, you can browse our large selection of premium quality motocross/dirt bike pistons, rings, connecting rods, and components, and choose among quality replacement or custom models.
