Derestricting Your 50cc Scooter: Everything You Need To Know

By | October 25, 2022

How to derestrict your 50cc scooter, including everything you need to know to do it safely! Restricted 50cc scooters have a maximum speed limit of 25 miles per hour, but by modifying the engine and carburetor, you can increase your scooter’s top speed by 10-15 miles per hour and make this minor adjustment without breaking the law.

A 50cc scooter can seem pretty powerful once it’s derestricted, but you may wonder if it’s really worth the cost to do so and what happens when you derestrict your 50cc scooter?

In this article, we’ll look at why many people choose to derestrict their 50cc scooters and how they go about doing it. We’ll also talk about some of the benefits and risks that are associated with derestricting your 50cc scooter and how you can be prepared to deal with them accordingly.

What is Derestricted?

Derestricted electric scooters are motorcycles with electric motors that fall under a lower emissions category. They are only road legal in some countries and states, but they can often be modified to fit other laws and restrictions.

To derestrict or not to derestrict is a common question among those shopping for a new electric scooter—but if you’re looking for information about how much power your model has and if it’s worth investing in one, there are plenty of resources available. But before you take any steps toward modifying an existing vehicle, it’s crucial that you check with local authorities about regulations in order to avoid tickets or fines!

If you’re just looking to make sure your model meets safety requirements, it’s easy enough to find out; all you need is your electric scooter’s wattage rating. Here are a few simple things you can do to learn more about restricters and how they work: – Take a look at motor specifications on product pages or spec sheets from online retailers (eBay also has some great info). – Look up your state’s moped/scooter/motorcycle registration requirements online.

How To Ride An Electric Scooter

Do I Need To Derestrict My Bike?

If you’re looking to ride a 50 cc motorcycle or scooter on a restricted driver’s license, first consider whether or not you even have to. In some states, a permit is required if a motorcycle rider is under age 18. Other states require riders of all ages to have at least 80 hours of experience on motorcycles before they can get their license.

If one of these things applies to you, then read no further and contact your local DMV for more information. But if neither of those apply, then you may be wondering why your state requires that you restrict your bike in the first place.

The answer boils down to safety. A restriction limits a rider’s speed and power output so that it’s safer for them to operate than it would be otherwise. It also ensures that new riders learn how to handle low-power machines in low-risk situations before graduating up to higher-powered bikes with greater performance capabilities.

My Scooter Won’t Start – What’s Wrong With It?

One of two things is almost always wrong with a non-starting scooter. Either there’s no spark (aka a dead battery), or it’s flooding (which is caused by an overflow of fuel.) When an engine won’t start, but cranks, it can be frustrating. But relax! If you follow a few simple steps—specifically about checking your spark plug and spraying carb cleaner into your carburetor—you can determine whether or not repairs are in order.

The following guide will walk you through diagnosing common problems that cause non-starts on small-engined machines, including mopeds and motorcycles. You’ll also learn how to fix them at home.

Let’s get started! I Just Changed My Spark Plug – Why Won’t My Scooter Start?: You’ve got gas in your tank, oil in your crankcase, and new spark plugs…but still no go? First off, make sure you’ve actually replaced all of those parts. Second, check for air leaks around wires and hoses where they connect to metal components like kickstands and mufflers. Next up? Examine both your carburetor and fuel line for water damage or any sign that one might have burst under pressure.

How Do I Derestrict My Scooter?

If you want to derestrict your 50cc scooter, you’re going to need a few things. First, check with your state and make sure it’s legal. (In some states, people can only derestrict motorcycles.) Next, get a copy of the owner’s manual for your motorcycle.

On page 4 under Safety Precautions, there should be an explanation about how to derestrict it as well as general precautions and warnings about how often or in what condition or under what circumstances or conditions you should not ride after removing restrictions.

Finally, if it is legal where you live and if possible, get training from someone who has experience derestricting small engine vehicles so they can walk through with you what they did exactly. After all that—get ready!

What Happens When You Restricit And DeRestrict A 4 Stroke Engine?

The process of derestriction is also known as unlocking, and when done, it effectively makes a 4-stroke engine behave like a 2-stroke. There are two types of derestriction – mechanical and electrical. Mechanical derestriction involves modifying or replacing parts of the engine. Electrical methods involve using special controllers to modify how an ECU (engine control unit) behaves.

In both cases, derestrictors must be installed by a qualified mechanic to ensure safety. Before deciding on which method to use, consider what kind of riding you plan on doing with your modified scooter. A lot of people choose electrical methods because they’re easier and less expensive than mechanical ones.

However, for more serious riders who want their engines to run at peak performance levels for competition purposes, mechanical modification may be necessary.

Tuning 4 Stroke Engines In General

Tuning a four-stroke engine is generally easier than a two-stroke. That’s because they are less sensitive to things like lean-burns and octane ratings, meaning it’s easier to get their engine running correctly without using race fuel. Because of that, we’ll cover tuning a four stroke engine first before moving on to two strokes. We’re not covering carburetors here–just ignition timing and jetting.

The basics are essentially all universal; if you know how it works on one bike, most of what we’ll be talking about will apply on any other bike with only minor differences between brands or models. As always, you should check your owner’s manual for details specific to your particular bike.

If you have no manual (or don’t understand it), take your bike in for service. It may be free depending on where you bought it from. Just make sure they use genuine parts and follow manufacturers specifications when doing so—you don’t want them replacing an expensive part just because it looks weird when there’s nothing wrong with it!


How fast can a Derestricted 50cc go?

The best way to answer how fast a derestricted 50cc will go is with a bit of knowledge on how they derestrict their bikes. To find out what speed it can go, you first have to find out what restrictions it has on it.

How do you make a 50cc scooter go faster?

That depends on where in Australia or New Zealand you live. In New South Wales and Queensland, for example, it’s prohibited by law to derestrict a 50cc scooter, because of safety concerns. However, in other states such as Victoria, riders are allowed to derestrict their bikes.

How fast is a 50cc moped in mph?

Most mopeds top out around 30 miles per hour, but that’s not much faster than an average bicycle. However, many 50cc mopeds can go faster than their speed limit thanks to de-restriction, or modification that removes a device put in place by manufacturers limiting top speed.

How fast can a Derestricted 49cc scooter go?

You can easily reach a top speed of 30 miles per hour with an unrestricted 49cc or 50cc scooter, but how fast will it go when you derestrict it? That depends on a few different factors.

First, let’s break down how and why exactly a 49cc or 50cc engine would be restricted in the first place. After all, if you’re even thinking about derestricting your engine, it means that either

How much power can you get out of a 50cc motor?

One of the most common questions asked when buying a new 50cc motorcycle is how much power can I get out of it? There are many factors that go into determining how much power a particular motor will produce.

Let’s take a look at some of those and see what we can find. First thing we’re going to talk about is cubic centimeters. Cubic centimeters, also referred to as cc’s, describe not just engine displacement but also horsepower and torque.


For many people, a 50cc scooter is perfect for getting around town and running errands. They’re compact, cheap to fuel and easy to handle—and when they get up and rolling, they can even pack a punch. But if you’re looking for a little more speed and power from your bike, derestricting it could be an option for increasing performance.

What does it mean? To put it simply, reworking your engine will increase its horsepower. This means more pep on take-off and more overall power. If that sounds good to you (it should), follow these steps below!
