How Hot Does a Motorcycle Exhaust Pipe Get?
1 Answers
Motorcycle exhaust pipe temperatures typically range from 300-150°C, gradually decreasing from the front section to the tail end, with the highest temperatures exceeding 500°C. Relevant details are as follows: Exhaust: During normal riding at 60 km/h, the front section near the engine reaches around 300°C, while the middle section near the footrest is about 150°C. When climbing a long slope in 1st or 2nd gear for an extended period, the engine runs at high RPM with low speed, causing the front exhaust section to rise to approximately 500°C, the middle section to about 300°C, and the rear section to around 150°C. Engine: During operation, the high-speed movement of piston rings and gears generates significant friction, producing substantial heat expelled through the exhaust. The exhaust pipe heats up continuously during this heat transfer process. The thinner front pipe near the engine is hottest (about 300°C), while the thicker sections near the kickstarter are cooler (150°C). The rear section is around 80°C. When riding mountainous terrain in 1st or 2nd gear with engine RPM reaching 5500, the exhaust pipe near the engine may glow red, indicating temperatures up to 800°C, while the kickstarter area reaches at least 300°C.
