If you love to ride your dirt bike on the most rugged terrains, you have probably considered modifying it so that your motorcycle could satisfy your demands for power, efficiency, handling, safety, and comfort. After installing an aftermarket exhaust, a new set of sprockets and tires and after tuning your suspension to match your riding style and trail conditions, it is time to get to the heart of your machine, its engine. The motor creates power and torque that moves the vehicle forward. In case you wish to accelerate faster or reach higher maximum speed, consider upgrading your powerplant with our premium-quality motocross or dirt bike engine parts.
We carry a wide assortment of cylinder heads, engine blocks, cylinders, crankshafts, camshafts, valves and valvetrain parts, timing gears and chains, pistons, rings, connecting rods, oil filters, pumps, gaskets, and all of the needed hardware and mounts. Whether you want to upgrade your engine or restore the factory characteristics of your stock unit, we have you covered. On the digital shelves of our online store, we showcase only high-quality dirt bike engine parts designed and produced by some of the most reputable manufacturing companies in the game, such as Wrench Rabbit, Athena, Cylinder Works, All Balls, K&M, and many others.
One of the main components of the motor is a cylinder head. Its dimensions can greatly affect the resulting power. Larger intake and exhaust ports can accommodate larger valves designed to deliver higher volumes of fuel and air mixture into the combustion chamber and ensure quicker evacuation of exhaust gases. Shortened valve guides can accept higher lift cams. A big bore cylinder made from aircraft-grade aluminum works perfectly with a large forged piston. If your camshaft timing chain needs replacement, you have come to the right place. Note that not all kits include a master link, and you may need to purchase it separately.
