Power performance
150CC has a larger engine displacement and usually has higher maximum power and torque. This makes 150CC scooters more advantageous in acceleration, climbing and high-speed driving, with stronger power output and a more rapid driving experience. For example, when carrying people or goods, 150CC scooters are easier to accelerate and climb than 125CC scooters. 125CC scooters are relatively weak in power and are suitable for smooth urban roads. They can meet daily travel needs when riding alone and in good road conditions, but may be a little strenuous when climbing or carrying people.
Fuel economy
Generally speaking, 150CC scooters have relatively high fuel consumption because the engine needs to consume more fuel to generate power, and its fuel consumption per 100 kilometers may be around 2.5L. 125CC scooters have a smaller displacement and are more fuel efficient, with a fuel consumption of about 2.0L per 100 kilometers. Over a long period of use, 125CC scooters will save more fuel costs.
Engine vibration
The engine equipped with 125CC models usually vibrates more gently, and can remain within an acceptable range even at high speeds. The vibration of the 150CC thimble engine is relatively large, which may affect the riding comfort.
Vehicle weight and volume: Since the engine displacement of a 150CC scooter is larger, it requires a stronger frame and suspension system to support it, so its vehicle weight and volume are generally greater than those of a 125CC scooter. This makes the 125CC scooter lighter and more flexible when driving and parking in the city, and more suitable for shuttling in narrow streets and crowded parking lots.

Vehicle configuration
150CC scooters are usually more equipped. Some high-end models are equipped with functions such as ABS anti-lock braking system, TCS traction control system, tire pressure monitoring, smart car networking, etc., and may also be equipped with airbag shock absorption, keyless start and other configurations, which can significantly improve the comfort and safety of riding. 125CC scooters are mainly based on basic functions, such as LED light source, LCD instrument, etc. A few models are equipped with CBS brake linkage system, and ABS and other safety configurations are relatively rare.
Usage scenario
125CC scooters are more suitable for short-distance commuting in the city. They have a short wheelbase and a light body. They are more convenient for frequent starting and stopping in the city and driving on narrow roads. The flat pedal design is convenient for placing items, which can meet daily shopping and other cargo needs. 150CC scooters have a larger fuel tank and a longer endurance. For example, the Cyclone RT150E is equipped with an 11L fuel tank and has a range of up to 400km, which is more suitable for long-distance commuting or occasional surrounding tours. However, 150CC models often use a "keel" structure to enhance the rigidity of the vehicle body. The cargo space may be limited, but the riding stability is better.
