Motorcycle Oils

Motorcycles are powered by either two-stroke (2T) or four-stroke (4T) engines. In a two-stroke engine, fresh air intake and compression occur during the upward movement of the piston, while combustion and exhaust take place during the downward movement. Since a complete operating cycle is completed in just two piston strokes, these engines are referred to as two-stroke (2T) engines. Some motorcycles, outboard marine engines, lawn mowers and chainsaws are examples of equipment powered by two-stroke engines.

In four-stroke engines, the intake, compression, combustion and exhaust processes that make up a complete operating cycle occur over four piston movements. For this reason, they are known as four-stroke (4T) engines. Passenger cars, buses, trucks and construction equipment are common examples of vehicles powered by four-stroke engines.

The Opet Fullmoto Series offers a comprehensive product range for both four-stroke (4T) and two-stroke (2T) engines. Thanks to advanced lubricant technology, Opet Fullmoto products help keep engines and engine components clean, ensure smooth operation and contribute to a longer engine service life.
