in NH all you need to get a title to register a dirtbike is to bring a piece of paper saying your motorcycle is street worthy and can pass inspection into your local townhall with the bill of sale

they will register your bike and in about 4 to 6 weeks you'll get a title in the mail

I did it with my full race supermoto in my avatar

and my buddy did it with his new ktm 300 sx, also his KLX and an XR

its also for sale : )
