It's not an easy task if you want to do it the legitimate way! You can ride it unmodified I.e. Dirt tires, no mirrors turn signals etc. But that's classed as an agricultural vehicle and you can't go over 15 mph and over 1 or 2 miles from you home.
The route I've gone is plg which is a car registration, so it has to have all the things your car has, horn, turn signals, road legal tires. This way you have to pay road tax but I can drive anywhere at the speed limits.
And the best thing about it is the banshee is the cheapest quad to insure as its a 350, raptors are crazy money to insure as everyone thinks they're the fastest because of the engine size.
