I don't have a license and haven't ridden even a dirtbike since I was like 14...
...Classes, are they worth it? I've never driven a street bike.
I'm thinking about a ninja 250, mainly due to the $3,500 price tag and astronomical gas mileage... They also seem to have a great resale value. The low output seems like it would be nice to learn on... but will I grow out of it quickly? I don't need a rocket, just something I can get on the interstate comfortably with.
