Rotax engines are widely used in various machines such as motorcycles, ATVs, Ultra-light Aircraft, and personal watercrafts. They are an Austrian brand, renowned for their efficient performance in challenging environments. Here is a simplified description of how a typical 2-stroke Rotax engine, commonly used in snowmobiles and jet skis, operates:

1. Intake: At the beginning of the process, the piston is at the top of the cylinder, this is known as the top dead center (TDC). As the piston begins to go down, it creates a vacuum in the cylinder. This causes the intake valve to open, allowing the air-fuel mixture to be drawn into the crankcase, which is the space where the crankshaft is located.

2. Compression: As the piston moves back up, it pressurizes the air/fuel mixture in the crankcase. The pressurization makes the intake valve close, effectively sealing the air/fuel mixture in the crankcase.

3. Ignition: On the next downstroke, the pressurized air/fuel mixture from the crankcase is forced to move through a transfer port into the cylinder. As the piston goes up again, it compresses the air/fuel mixture. When the piston reaches near the top of its stroke, the spark plug ignites the air/fuel mixture causing an explosion. This explosion forces the piston down again, creating power.

4. Exhaust: On the upstroke after the explosion, exhaust gases are forced out through an exhaust port by the piston. The piston reaches the top again and the exhaust gases are released. The cycle then starts all over again.

Meanwhile, 4-stroke Rotax engines (commonly used in some recreational aircrafts and motorcycles) follow the traditional four-stroke cycle of intake, compression, power (or combustion), and exhaust.

Please note that how a Rotax engine works might vary depending on the specific type of Rotax engine, what machine it's powering and what fuel it uses.

The lifespan of motorbike tyres can vary significantly based on several factors, including tyre composition (soft, medium, or hard compound), riding style (aggressive vs. conservative), road conditions, and maintenance practices. Generally, motorcycle tyres can last between 3,000 to 15,000 miles. Soft compound tyres, which offer more grip, may wear out faster, especially if used aggressively or on poor road surfaces. Hard compound tyres provide less grip but typically have a longer life. Regular checks for tyre pressure, tread depth, and signs of wear or damage can help maximize tyre lifespan. Moreover, storing the bike properly and avoiding exposure to extreme temperatures or sunlight can also prolong tyre life. Ultimately, adhering to the manufacturer's recommendations and observing your riding conditions and habits will be key in determining how long your tyres will last.
