Is it harmful to a 125cc scooter to run at 90km/h?

[DelAnna]

Running a 125cc scooter at 90km/h is harmful. Maintaining this speed for a long time can lead to increased fuel consumption, cylinder scoring, and reduced engine lifespan. Increased fuel consumption: If the fuel system of the motorcycle hasn't been inspected or cleaned for a long time during use, it will affect its speed performance to some extent. Cylinder scoring phenomenon: There are many engine faults that can cause this inability to reach higher speeds, such as insufficient cylinder pressure, clutch slippage, or changes in valve timing, all of which can produce such reactions. Impact on engine lifespan: For the engine, the combustion chamber is subjected to high temperature, high pressure, and corrosive effects of combustion gases, making it difficult to maintain the lubricating oil film. Especially during piston movement, constant contact with fresh air makes the engine cylinder liner more prone to damage.
