• How can I make a dirt bike street legal?

  + −
  You can make an off-road dirt bike street legal, but it involves quite a bit of work. The bike will need DOT approved features like, legal turn signals, rear brake lights, a headlight with high and low beams, street tires, street exhaust, mirrors, horn, instrument gauges (odometer or speedometer) and of course, a license plate holder and plate from your state. You may also have more state-specific guidelines and requirements you’ll need to meet. You may also have to have the converted off-road bike inspected and approved by your state’s DMV. Some state DMVs will not approve an off-road dirt bike as street legal if the Manufacturer’s Statement of Origin (MSO) defines it as “off road use only.”

• How fast does a 125cc dirt bike go?

• What is the difference between a dual sports bike and an off-road dirt bike?

  + −
  Although they share similarities to the untrained eye, dirt bikes are lightweight, fast, powerful, need more maintenance and primarily intended for riding off road. In most states, it is illegal to drive a dirt bike on the street. On the other hand, dual sport bikes have all the legal DOT features required to drive on the road but have off-road capabilities and tend to weigh more than off-road dirt bikes.

• Do you need a license for a dirt bike?

  + −
  Most states do not require you to have an operator license for a dirt bike. If you are riding on private land, you probably won’t need a license, but if you plan on riding at a local state riding park, motocross track or trail, you may have to abide by certain regulations such as state registration and titling. Or, have the appropriate off-road riding association membership.

• Do you need insurance for a dirt bike?
