According to Michael Benes, making dirt bike street legal is easy. You must install the necessary bike parts in compliance with your state’s DOT rule. Laws differ per state. But generally, here is a list of parts and accessories to fix to make dirtbike street legal

  • Tail lights

Tail lights are important across all the states. They make you visible on the road and communicate your next moves. Also, they serve as brake lights for the front and rear brakes. This tells other road users that you're slowing down or stopping.

To make the dirt bike street legal, you must install the switch such that the front lever and the rear brake pedal trigger it. You can achieve this through pressure connectors. 

Many people use a banjo-bolt switch with more pressure in the brake line. This helps to trigger the tail lights or the mechanical switch. This switch is suitable for drum brakes. A banjo bolt enables easy installation of a pressure-activated tail light switch without adding a tee fitting.

In some states, you must leave the tail light on every time. You must also connect it to a battery source that can sustain it for at least 20 minutes.

You should consider using LED lights for your dirt bike tail light. This helps to reduce how much power it uses and extend the battery's life.

  • Headlights

Headlights are also required in all states in the US to make dirtbike street legal. Functional headlights will help keep you and other road users safe. It does this by enhancing your ability to see at night or during extreme weather. Also, it indicates to others that you're riding.

They must function during the day and night. You should be able to switch them between low and high beams. Furthermore, you should add indicator lights to show which beam is on. But you should be careful with your headlights and ensure it's not too blinding to other drivers.

The DOT rule on the high/low switch placement is installing it in a visible place. Thus, install the switch in a spot you can access. 

  • Mirrors

You need mirrors to make a dirt bike street legal. You can see what's behind you with functional mirrors, boosting road safety. In some states, you need two functioning rear mirrors. In others, at least one working mirror is okay.

Two mirrors are better as you get a wider scope of what's happening behind you. While maintaining the law is important, so is your safety. Thus, avoid using cheap or shaky mirrors. Instead, use wide-angle mirrors and long-stem mirrors. You may also install bar end mirrors if your bike isn't designed to accept them.

  • Turn signals

Many states don't require turn signals. So, you should confirm before installing, though it doesn't hurt to do that. Instead, they prefer that you signal with your hands when turning. Installing turn signals will help you keep your hands on your dirt bike. This helps when turning to avoid losing control.

Flashing turn signals are especially helpful at night when other users can hardly see you signaling with your hand. Check with your state requirements for installing turn signals on dirt bikes. 

Generally, you should install them on the left-hand grip. This is to enable easy usage without letting go of the throttle and visibility. You should consider using LED blinkers for your signals to reduce power usage. 

  • A side stand

You don't exactly need a side stand to make a dirt bike street legal. This is often due to safety concerns that the stands may cause the bike to fall off or catch onto things. 

But having a side stand benefits you as it helps you easily park your dirt bike.  It will save you the hassle of finding a parking spot or breaking the law by resting your bike against a wall.

  • Horn

To make riding it legal, you must have a functional electric or nonelectric horn on your dirt bike. But some areas require that the horn be electrical. So, confirm which applies to you. It's easier and safer to install an electric horn to avoid issues with the government. 

They are also quite affordable, draw less than 10 amps, and setting up a charging system is easy. Finally, they don't use too much electrical power, so you won't experience power issues.

  • Tires

You must use tires that are Department of Transportation (DOT) certified. This boosts road safety and ensures you don’t fall off your bike when on the road. Generally, DOT-approved tires are often marked DOT in the sidewall. They also tend to contain extra layers of rubber.

While you may get away with using basic off-road tires, they may not last. The seams may fall apart after many uses. DOT-certified tires last longer, are lightweight, and boost maneuverability on the road.

  • License plate holder

You need a license plate holder to make your dirt bike street-legal. The bike must display the license. Regulations for placement and location of the license plate holder differ. Some states require that you put the holder behind the rear wheel for easy readability. The important thing is that it must be visible from the bike's rear.

Furthermore, a light must illuminate the holder when on the road. There, mount a LED strip above the plate to enable visibility.

You must also fasten it to prevent it from falling off when riding the dirt bike. Consider using zip ties or mounting the plate beneath the fender. 

  • Stator

You need a stator to generate electricity on your dirt bike. It works with dirt bikes without lights. A stator also works with minimal electrical requirements, likely producing minimal wattage. 

It should have about 13 to 15 volts left to charge the battery after the electrical parts draw power. You may consider using a high-output stator to generate more power for your dirt bike and to make it last longer.

  • Regulator

Adding a regulator to your dirt bike to make it legal is not compulsory. But you may need a regulator or rectifier to use with the stator. It converts alternating current from the stator to direct current. 

Furthermore, it regulates the high voltage from the stator. Thus, bringing it down to the required 13 to 15 volts needed to charge the battery.

Find a regulator that's compatible with the stator for functionality. Avoid operating the lights off alternating currents, especially when they can't handle them.

  • Battery

Batteries are not compulsory to make dirt bike street legal. But they come in handy to prevent the lights from dimming. The lights tend to dim when the bike is idle, and you need lights to keep the law. There are small batteries available meant for making dirt bikes legal.

Some types can work as only power sources, while you need to combine others with a charging system. Both types function well and supply the power needed for your bike. But the former tends to drain fast and needs frequent charging.

  • Charging system

You should consider getting a charging system for your dirt bike or upgrading it to power the lights. This may need upgrading the stator to power other components like the battery.

  • Documentation

Asides from the mechanical parts, making dirtbike street legal requires documentation. Documentation for verifying your bike varies between states and countries. So, check for state and federal standards. 

Some states need the Manufacturer's Certificate (or Statement ) of Origin. Other states may need:

- a NOVA declaration

- an Inspection Certificate that signifies approval for the bike to operate on main roads

- a number plate

- a V5 log book, and insurance

You may also need proof of ownership, a valid driver's license, an odometer statement, and a certificate of equipment compliance. Research what your state requires from you. Then prepare the documents and seal the legal use of your dirt bike on the road.


All requirements for making your dirt bike street legal are for your safety and other road users. However, researching your state's requirements is crucial to making a dirt bike street legal. Install accessories, parts, and other necessary things to keep you safe and make the bike last long. Good luck!
