Riding is so much fun, and it’s no wonder that many start by looking at 50cc options. They can fall into the gray area in some places with licensing, and they tend to be the most affordable transportation options. That said, how fast will a 50cc engine go?! How much zip can you expect?

50cc engines are expected to reach a maximum speed of 30 miles per hour (mph) if restricted. If unrestricted, 50cc engines have been reported to reach up to 43 mph without additional modifications.

Scooters in particular are designed to be an economical and environment-friendly transportation options, especially when compared to cars! It’s part of why 50cc scooters have risen in popularity, particularly among age 16 years and above. They favor their ability to maneuver within the neighborhood areas and cover short distances within the city. They are lightweight and relatively slow speed to start riding on or can be fun & zippy for the experienced rider.

What does 50cc mean?

To explain it in simple terms, CC is short for the measuring unit cubic centimeters. Cubic centimeter measures the capacity of the engine to burn air and fuel to create horsepower. Put simply, it is the volume of air and fuel that the engine burns to generate power.

Vroom! Vroom!

The technical terminology for this capacity is engine displacement. An engine with high displacement can burn higher volumes of energy and thus generate higher power. So, if we interpret the label 50cc engine, we can say that the engine can burn 50 cubic centimeters of air and fuel to generate power.

When we are talking scooters, sometimes scooters with an engine size of 50cc will be called a moped. What we call scooters gets confusing, so check out this article to go down the rabbit hole

How fast is a 50cc two-stroke vs a four-stroke in mph?

Whether an engine is a two-stroke or a four-stroke matters when we are talking the speed of what a 50cc can produce. The quick answer is that four-strokes are more fuel efficient, but when we’re talking power, you’ll find more of it in the two-stroke.

A 50cc two-stroke engine has 5-7 horsepower which translates to speeds in the 40-50 miles per hour range. A four-stroke engine has 3-5 horsepower and translates to speeds in the 35-43 miles per hour.

If a scooter is advertised with a maximum speed of 30 miles per hour, it has been artificially restricted to meet the safety or regulatory requirements that has them in the lighter licensing requirements that attract some to this size.

Which is faster, 50cc or 150cc?

Recall that cc represents the power an engine can produce. In this case, it is easy to compare as it is just a matter of comparing the numbers. A 150cc engine is faster than a 50cc as it produces more power through the increased displacement.

A 150cc engine is faster due to its bigger size, and top speeds are seen in the mid 60 mph range. Mopeds are good for inner-city, shorter rides, and the 150cc will be good on those rides, as well, with hills. The larger engine sizes will give more flexibility to travel further with the higher speed available to it.

What is the top speed of a 50cc scooter in mph?

A 50cc scooter generally reaches a top speed of 35 to 40 mph depending upon whether its engine has been restricted by the manufacturer or altered to achieve maximum speed. It is not unheard of to reach 45 mph on a two-stroke in particular.

That said, the more weight the engine has to move, the less likely it will be to reach it’s top speeds. This can mean the items you’re carrying, an extra passenger or even heavier riders.

What is the top speed of a 50cc scooter in kph?

While the top speed of most 50cc scooters with a restricted engine is 48 kilometers per hour (kph); whereas some manufacturers have built 50cc engines that can comfortably reach a top speed of 65 kph.

What other benefits does a 50cc engine has to offer?

Easier handling

Unlike other engine sizes, a 50cc engine is lighter and easier to handle on the road. Much credit goes to its speed limit that does not exceed more than 30mph. It allows the riders to maneuver the scooter with ease. These are great options for beginners while minimizing any risks of fatal accidents or serious injuries.


A 50cc engine is one of the most affordable means of transportation. A scooter or moped with a 50cc engine costs nothing when compared to a motorcycle and car. 50cc engines are no doubt a pocket-friendly option.

Fuel efficient which helps you save a lot of money

50cc engines are the most fuel-efficient and cost-effective motor vehicles. It is one of the critical factors buyers consider when making a purchase. Roaming around for 100 miles on a gallon is economical and relatively more environmentally friendly than any other means of transportation. Due to this reason, youngsters and especially students prefer 50cc scooters and mopeds.

It helps you skip long queues swiftly

Due to their small size, 50cc scooters and other two-wheeled vehicles are easier to handle in traffic and long queues. You can also take the bus lane on the road, enabling you to skim through traffic jams with greater ease and comfort, saving you an ample amount of time. Reaching a destination on time is easier and more possible.

No trouble finding a bike parking

With so many vehicles on the road, finding a parking spot is has become a mission impossible in modern times. Vehicle owners dread looking for car parking in most downtown areas. The petite size of a 50cc scooter makes it easier to squeeze it into a tiny spot for parking.

Does it require a license for driving a 50cc engine?

Most states in the US do require a driving license for riding a 50cc engine. The law also requires that the rider of the scooter be no younger than 16 years of age. It is imperative to know that owning a valid driver’s license ensures safety not only for yourself but also for others on the road. 


50cc engines emit lesser volumes of fuel combustion as compared to other types of vehicles, which makes them an excellent resource for being eco-friendly.
