Does Using First Gear for a Long Time Damage a Motorcycle Engine?

Using first gear for a long time generally does not damage a motorcycle engine, but it can cause the engine to overheat. First gear is characterized by high RPM, high torque, and low speed, which puts a heavy load on the engine, causing it to heat up quickly and dissipate heat poorly. First gear is the starting gear: As the starting gear, first gear should be shifted to a higher gear once the motorcycle gains speed. Failing to do so can result in "lugging," which increases fuel consumption and damages the engine and transmission system. Effects of lugging: There are two types of lugging: low-gear high-speed lugging and high-gear low-speed lugging. Neither is a good phenomenon, as both negatively affect the engine and increase fuel consumption. Low-gear high-speed lugging forces the engine to operate at excessively high RPMs. Each engine has its specific RPM-power characteristics, and exceeding the optimal operating range leads to a sharp increase in fuel consumption while also placing excessive stress on engine components due to ultra-high-speed operation.
As an experienced motorcycle enthusiast, I believe prolonged use of first gear is indeed harmful to the engine. Firstly, running the engine at high RPM increases friction between the cylinders and pistons, leading to overheating and accelerated wear. Especially in urban traffic congestion, constant use of first gear causes oil temperature to spike, thickening and aging the engine oil, thereby reducing its protective capabilities. The clutch also suffers, as prolonged high-load operation can cause slipping or burning, increasing maintenance hassles. Occasional use for climbing hills or low-speed riding is fine, but doing this daily can shorten the engine's lifespan by several years. I recommend developing the habit of timely upshifting—it protects the engine while also saving fuel and reducing noise. After all, motorcycle maintenance is expensive, and saving money on engine repairs is better spent on new gear.
I've been riding motorcycles for over a decade and learned some lessons the hard way. I remember once when I was delivering food, I often stayed in first gear to save time, which caused the engine to overheat and become noisy. The mechanic said prolonged high RPMs led to carbon buildup and accelerated wear on the valves and bearings. Later, I started shifting normally, and the engine performance became much more stable. Actually, first gear is suitable for low-speed uphill climbs, but on flat roads, you should shift up—otherwise, the engine can overheat, leading to oil burning or leaks. Plus, the clutch wears out faster, making replacements time-consuming and labor-intensive. Regularly checking the oil level and cooling system helps catch issues early and saves trouble. In short, good habits keep the engine from breaking down easily.
Keeping a motorcycle in first gear for extended periods with the engine operating at high RPM poses significant wear risks. I believe it accelerates friction in the cylinders and bearings, leading to rapid oil consumption and even overheating that can burn out components. Maintenance-wise, more frequent oil and filter changes are required to prevent cumulative wear. Don't ignore noise and vibrations, as they affect riding comfort. Occasional low-speed use is fine, but persistent operation in this manner can halve engine lifespan. Simple maintenance can prevent serious issues.
