What is the difference between 125cc and 150cc power?
2 Answers
125cc and 150cc power have the following differences: 1. Different displacement: 125 and 150 here generally refer to the nominal displacement of the engine. A 125cc motorcycle specifically refers to a motorcycle with an engine displacement around 125CC, while a 150cc motorcycle refers to one with an engine displacement around 150CC. 2. Different performance: Mainly divided into bored engines and non-bored engines. For bored engines, only the cylinder block, piston, and piston rings are different, whereas for non-bored engines, in addition to these three differences, there are also differences in intake and exhaust valves, carburetor diameter, exhaust pipe diameter, air filter diameter, number of clutch teeth, and the crankshaft is also different.
I think the main difference between 125cc and 150cc engines lies in performance. As someone who rides frequently, I’ve noticed that a 125cc engine starts up a bit slower, accelerates smoothly but struggles when overtaking, with a top speed of around 70-80 km/h. After switching to a 150cc, the power surge is obvious—throttle response is much quicker, overtaking becomes effortless, and the top speed can reach 90-100 km/h. It’s especially noticeable when climbing hills, making the ride much more enjoyable. In terms of fuel consumption, the 150cc burns slightly more. A 125cc can easily cover 45-50 km per liter, while the 150cc might drop to 35-40 km. But for that extra power, I’d gladly pay a bit more for fuel. Additionally, the 150cc vibrates less at high-speed cruising and offers better stability, making it ideal for speed-loving young riders. However, for city stop-and-go traffic, the 125cc is hassle-free. It really depends on personal needs.
