Why Convert Your Dirt Bike?

For most people, converting an off-road dirt bike to a legal street dirt bike is purely economic. After having great off-road ventures, someone may consider converting their machine into street-legal instead of purchasing a second bike. It is the cheapest way of effectively using an off-road dirt bike.

Another reason is the comfort. People have different tastes and preferences. In other words, someone may find the ergonomics and the performance of a dirt bike great and therefore decide to stick to it instead of jumping into street bikes. The performance and riding style can easily make people fall in love with off-road dirt bikes.

How To Make Your Dirt Bike Street Legal

The different States in the US have different opinions regarding the threshold for street legal dirt bikes. Therefore, knowing the rules and regulations in your state and getting all the critical paperwork will ensure that you do not experience any problems with the authorities. Generally, you will need to do the following to turn your dirt bike street legal.

Upgrade The Electrical Systems

Considering that most parts and accessories you will need to add to your dirt bike are electrical-oriented, you may consider upgrading your electrical systems. With the help of the bike's service manual, you can easily understand how the electrical system in the bike works.

If you find upgrading some parts like replacing the bike's charging system challenging, you should not hesitate to consult with those who have done it successfully.


Every state demands that you install a DOT-compliant headlight. Proper lighting makes sense because riding without lights is crazy. The DOT requires the headlight to have a switchable low and high beam, capable of functioning at night and daytime, and with a complete indicator light that tells the rider which beam is engaged.

Upgrading the electrical system to power-efficient LED units is essential as it helps conserve power. Further, it is crucial to determine the exact rule in your jurisdiction before purchasing your accessories.

Turn Signals

Turn signals are not mandatory in some states. However, there is nothing wrong with installing the turn signals, as it makes your turned off-road dirt bike more efficient and safer.

There are regulations on where and how the turn signals should be installed relative to the headlights and taillights. For instance, you need to install the switch on the left-hand grip for easy access. Further, it would be best to get your turn signals approved by the transport department.

Brake/Tail Light

All states require street-legal bikes to have functional brake lights. Some states require the tail lights to be powered by a reliable battery that keeps the light on for more than 20 minutes without assistance. To ensure that you can comply with these requirements, you should invest in LED lights because they are energy savers and can keep you safe.

The Exhaust

The exhaust is an essential part of a legal dirt street bike. Generally, there are three essential things that you should consider when examining your exhaust; shape, gas emissions, and sound levels. The State of California is stringent on the quality of the exhaust, meaning that it is one of the essential factors in approving street legal dirt bike conversions.

The best way to ensure that your exhaust does not become a stumbling block is by purchasing an EPA-approved exhaust and ensuring that you install them properly. They are best known for keeping emissions and sound levels within legal limits.

How To Make A Dirt Bike Street Legal In California

Since the State of California classifies dirt bikes as off-highway vehicles, they are subject to stringent emission regulations. Before you get the green lights to ride on the street, your dirt bike has to be certified by California Air Resource Board (CARB).

The easiest way to make your dirt bike street legal in California is to purchase a model that already meets the state's emission regulations and highway safety standards. It is the best way to avoid the expenses of converting an old non-compliant off-road dirt bike.

Nonetheless, it is essential to note that for your off-road dirt bike to be street legal in California, it must have a green sticker from CARB. Further, if your bike is not a green model, you will not be able to convert it to a street-legal bike regardless of the modifications you will make to its emission system.

Generally, you need to be familiar with three forms of registration before preceding the conversion process;

  • Bikes with red stickers: Refers to the bikes with poor quality emission systems and, therefore, cannot be converted to highway use regardless of the modification you make.
  • Bikes with Green Stickers: Refers to the types of bikes that meet the emission standards, either by modification or by manufacturer's design.
  • Street-legal dirt bikes: These have met the States emissions and are equipped with blinkers, windshields, horns, and other essential safety features.
