The Yamaha Genuine Cylinder piston kit comprises mainly of Cylinder, Piston and Piston rings.
Piston
The piston reciprocates in the cylinder at high speed and is constantly exposed to high temperatures (400 to 500°) and pressures (30 to 50 kgcm3). Its purpose is to transfer force from combustion gases in cylinder to the crankshaft.The Yamaha Genuine piston materials have optimised mechanical strength, thermal conductivity for good heat dissipation, low thermal expansion, etc. The piston must also be light Therefore, a Yamaha Genuine Piston (made of cast aluminum alloy) is the combined result of state-of-the-art material technology, microscopic Designing, manufacturing & machining technologies.
Cylinder
Cylinder is the central working part of the reciprocating engine. The purpose is to sustain combustion and guide Piston movement. Further its function is to dissipate heat of combustion through the fins present on the outer surface. Yamaha Genuine Cylinders are manufactured to cater optimised performance.
Piston Rings
Yamaha Piston rings are manufactured through high-precision (microscopic) machining. Its function is to provide sealing to the piston so that exhaust gases do not escape.
