How Fast Do 50cc Mopeds Go?

Out of the box, a 50cc moped will come with its top speed restricted or limited. This is to comply with various laws around the world governing what a moped is, as well as putting some limitations on engine size and speed.

A 50cc moped has a restricted top speed of 30 to 35 miles per hour (48 to 57 kilometers per hour), actually achieving this top speed will depend on factors such as the rider’s weight, the terrain, and the weather conditions. Different makes and models have slightly different top speeds, but as a rule, in restricted format, all 50cc mopeds will be close to the top speed above.

This isn’t to say that 30-35mph is the maximum top speed of a 50cc moped, in actual fact, some can zip along much, much faster!

If you want you moped to move faster than 30-35mph, then derestriction is the key. Derestricted top speed will be covered in the next section of this article, and you won’t believe the speed of the world’s fastest 50cc!!

In the table below are links to articles on the top speed of different mopeds where we cover the restricted and derestricted top speed of each as well as other useful information…

How Fast Can Derestricted 50cc Mopeds Go?

How fast do 50cc mopeds go when they’re derestricted? The answer to that question varies a lot depending on make, model and whether the engine is 2-stroke or 4-stroke.

A derestricted 50cc moped can have a top speed of up to 60 miles per hour (96 kilometers per hour), depending on the make and model. Derestricted 2-stroke mopeds are generally faster than 4-strokes, a derestricted 2-stroke should be able to achieve somewhere between 45-60 miles per hour (72-96 kilometers per hour), whereas a derestricted 50cc 4-stroke moped will normally achieve 40-45 miles per hour (64-72 kilometers per hour), with some 4-stroke models hitting the 50mph mark.

Whilst it is relatively easy to derestrict a 50cc moped, it is worth checking on the laws in your area, as in some places around the world, derestricting a moped is illegal.

What Is The Fastest 50cc Moped?

The fastest 50cc moped available today is the Aprilia RS50, which can have a derestricted top speed of an incredible 65 miles per hour (105 kilometers per hour). The Aprilia RS50 is unfortunately no longer available to buy from new, but you can still get good used examples fairly easily.

The Aprilia RS50 was built with style and speed in mind, and reigned champion in many regions of the world for many years. If you do find a good, used RS50, as with all derestricted 50cc mopeds, be careful of the laws in your area and check whether you are eligible to drive this moped.

If you’re looking for something different from the RS50, more like a traditional moped without gears, just rev and go, then the Yamaha Aerox 4 is another fast 50cc moped to consider. With a user reported derestricted top speed of up to 55 miles per hour (88 kilometers per hour) on a good day, this moped is a fast, stylish little machine. Again, new versions are unfortunately unavailable, however decent used examples are abundant.

Both the Aprilia RS50 and the Yamaha Aerox 4 are 2-stroke mopeds, which is how they are able to produce such stunning top speeds. As the world moves away from 2-stroke pollution, mopeds are more frequently utilizing 4-stroke engines, which just don’t offer the same top speeds.

Will a 2-stroke 50cc moped that’s been kept in good condition be worth a lot of money in the coming years? Now that’s a good question…

What Is The Fastest 50cc In The World?

Currently, the 50cc land speed record belongs to John Buddenbaum, a metal fabricator and Eric Noyes, a NASA engineer. In 2008 the pair (Buddfab team) set a new world record of 144.891 miles per hour (233.179 kilometers per hour) onboard their streamliner at the Bonneville Salt Flats.

The bike (which started life as an Aprilia RS50 and has a Minarelli AM6 base engine) looks nothing like a conventional motorbike, it’s a streamliner that was designed and built specifically for the purpose of breaking the 50cc land speed record. It is crazy to think that such a small motor can produce so much speed! Check out the history of the 50cc land speed record here.
