What size engine is it ? 650? I really wanted to get a bike this summer but i brought some double glassing instead Not really had much good weather for a bike yet. Have you seen the 4 wheel concept bike bikes like the Yamaha tessaract?
4 wheel bike? thats a convertible. you need two wheels for a bike, no more, no less. mine is just a 400cc, see the motorcycle mayhem thread for more details
