My first boyfriend (older) had a very cool, very huge motorbike. For the bikers out there, i believe it was a Kawasaki Ninja Niner.
The first time getting on, i was really nervous. It was much bigger than i expected. I got on anyway, wrapped up in leathers of course. He talked me through a couple of bits and bobs and we went for a ride. It was amazing! I loved it. He was an experienced rider and i trusted him. I wouldn't get on with a newbie though.
