The connecting rods included in the piston kit are also of superior quality. They are forged from tough materials, ensuring strength and durability while handling the immense pressures produced by the high-revving 4-stroke engine. The rods are carefully balanced to reduce vibration and ensure uniform power transfer from the pistons to the crankshaft.
The piston kit comes with matching rings - compression rings, oil control rings, and piston pins - that have a precise fit to the pistons and cylinder bore. These rings are essential for proper engine sealing and oil control, preventing the engine from losing compression and reducing oil consumption. With excellent heat dissipation properties, they ensure that the engine remains lubricated for extended periods, minimizing the chances of engine damage.
