Is It Normal for a Motorcycle Engine to Get Very Hot?

[GiselleDella]

It is not normal for a motorcycle engine to get very hot. Below are the reasons that may cause the engine to overheat: 1. A new or recently overhauled engine operating at high speed and power during the break-in period: During the break-in period, running the engine at high speeds or under heavy loads will inevitably subject the engine components to excessive stress, increase wear, and cause poor heat dissipation. Additionally, the engine oil may oxidize and degrade due to high temperatures. Early degradation of the oil can further impair its lubrication and wear-reducing functions, and in severe cases, the oil may turn into an asphalt-like substance. 2. Using engine oil with an excessively low grade or high viscosity: If the viscosity grade of the oil is too low, the oil film will be thinner, reducing its buffering effect on engine components and diminishing its wear-reducing properties. This can lead to increased wear and higher engine operating temperatures. Conversely, if the oil viscosity is too high, its flowability will be poor, resulting in less heat being carried away, which can also cause the engine's operating temperature to rise.
