What is the typical lifespan of a motorcycle engine in kilometers?

[McGrant]

Motorcycle engines generally have a lifespan of around 100,000 kilometers. With proper maintenance and after major overhauls, engines from certain manufacturers can reach up to 300,000 kilometers. Below are some relevant details: Motorcycle retirement period: National regulations stipulate a service life of 10 years for two-wheeled motorcycles, which can be extended by 3 years. However, during the 3-year extension period, semi-annual inspections are required, and the extension is only permitted upon passing these inspections. After 13 years, compulsory retirement is enforced. Additionally, motorcycles exceeding 100,000 kilometers must be retired. Motorcycle maintenance schedule and items: Regular oil changes are necessary at 300, 500, and 1,000 kilometers, with the frequency adjusted based on the quality of the oil used. The air filter should be replaced every 3,000 kilometers. Regular maintenance of the motorcycle battery is also essential, including periodic charging.
