What Does A Dirt Bike Need To Be Street Legal?

January 2, 2024
By Michael Padway

You enjoy getting away from it all by firing up your dirt bike and exploring out-of-the-way trails or blazing new ones. Less enjoyable is having to load the bike onto a trailer or pickup truck to transport it to the trailhead, unload it, and find a place to park before you start riding. 

It would be easier to just ride your dirt bike to the off-road site, but you would be breaking the law unless you have a street-legal bike. If you are thinking about converting your off-road motorbike into a dual-use machine that can be ridden off- and on-road, this guide gives you the information you’ll need, including equipment modifications and registration requirements before you attempt to ride your dirt bike on the streets. 

How Do You Know if You Have a Dirt Bike?

Manufacturers and state motor vehicle departments use two general categories of motorcycles. There are the street-legal or on-road machines you see cruising around town or along the highways. Dirt bikes or off-road bikes make up the second category of motorcycles. They are designed and equipped to take on and conquer the roughest terrain. 

Both categories of motorcycles come equipped with two wheels, a seat, handlebars, brakes, and an engine, so it may be difficult to determine just from looking at it whether that machine sitting in the middle of your garage can be legally ridden on the street. Here are a few ways to determine what are dirt bikes as opposed to their road-ready counterparts:

Size and frame

Dirt bikes need to be highly maneuverable to navigate across rough terrain and around trees, rocks, and other obstacles. They have smaller and lighter frames that make them more agile than heavier road bikes built for stability. The frame design also results in dirt bikes having a much higher ground clearance than street bikes to prevent them from hitting or getting stuck on uneven terrain, rocks, and other obstacles in their path.

Position of the rider

When you see a dirt bike in action, perhaps the first thing you notice about it is the position of the rider. Seats on dirt bikes are designed to let a rider lean forward to easily transition into a standing position to navigate hills and bumps and to maneuver over obstacles. Road bikes position their riders further back to maintain what may appear to be an almost lounging posture as opposed to the more upright position of dirt bike riders.


Low handlebars on dirt bikes increase a rider’s ability to react to changes in the terrain by quickly adjusting the direction of the bike. Handlebars on street bikes can be higher because steering adjustments can be accomplished by leaning rather than by relying as much on the use of the handlebars as riders of dirt bikes must do.


Traction is the key when riding off-road, so dirt bike tires are designed to provide maximum traction with a knobby tread rather than a tread used for street bikes. They are narrower than tires used on street bikes, which makes them better suited for riding through loose dirt and rocks and other riding surfaces not encountered on paved roadways.


The suspension system of an off-road bike must be loose enough to absorb the impact of dips and climbing over fallen trees and other obstacles. The same loose suspension system on a road bike would make for an uncomfortable ride, so manufacturers use a tighter suspension system.

One piece of equipment that should be used by riders of all motorcycles whether on the road or off-road is a properly fitting, DOT certified helmet. You can find helmets designed to meet the specific needs of off-road riders that maximize protection while reducing weight and increasing ventilation and airflow.

Why Do Riders Decide To Convert Their Dirt Bikes?

One reason to convert a dirt bike into one that is street legal is convenience. Maybe you’re tired of trailering the bike or loading it into the bed of a pickup truck each time you want to take it for a ride. Converting it to a bike that is street legal lets you ride it to your favorite off-road riding area. 

Or maybe, riding a dirt bike convinced you to make riding a motorcycle your go-to mode of transportation.

Buying a road bike to share garage space with your trail bike gives you the ability to take to the open road, but the financial commitment required to acquire a second motorcycle may not be one that you are prepared to make.

Besides, you may like the feel and performance of the dirt bike and not want to give it up for a dual-use motorcycle that is street legal as well as being suited for off-road use.

Something else to keep in mind when deciding whether to convert the dirt bike you now own to the one you can legally ride on the street is the commitment of time and money needed to take on such a project. You may discover that selling your current ride and buying one you can legally ride on-road and off-road makes more sense for you. The following sections about dirt bike laws throughout the country and what it takes to make a dirt bike legal to ride on the street may be of help to you in deciding whether to take on the project of converting your dirt bike.

Dirt-Bike Laws for Each State

Before jumping into a project to make your dirt bike legal to ride on the street, you need to research the dirt bike laws. This is no easy task particularly if your riding takes you across state lines. Each state has its own laws pertaining to licensing and equipment required for different types of motorcycles. Sometimes, there may be local laws enacted by county, city or town governments that supplement those enacted at the state level. 

To help you get started with your conversion project is a map to locate the laws in each state. Just keep in mind that laws change, so check with your state’s department of motor vehicles for updated information.
