The Hayabusa is probably one of the most modified and customized motorcycles ever produced, sooner or later, if it's been done to any bike, it will eventually be done to a Hayabusa. So, I wasn't too surprised when I saw this, but I have to think it could get a little interesting in high speed turns.
This trike, called the TT-Busa, does not appear to lean, it's sort of a Can-Am Spyder on steroids. They installed an extended swingarm with a 300 rear tire and custom built the 2 wheel front end. The obvious question in my mind, if you're not going to lean, why not put larger automotive tires on the front, or the rear, too?
This one is for sale, asking $34,999 and they'll build one for you, too. Hmm, .... Interesting.
