A story went about at the time that a number of Police forces in the UK were trialling Ford Fiestas fitted with Orbital engines, but no more was heard and the last reference I could find to it on the Web was from 1995.
That was until I found this video on YouTube:
However, I did find this video from BRP, parent company of Ski-Doo, Can-Am, Rotax, etc.
Of course, someone's already done something similar.
Kawa posted a link on Facebook to an article about this bike. It's an 800cc Rotax snowmobile engine fitted into a Kawasaki ZZR 1200 frame. The article mentions that it's a 2003 engine, so it might not have direct injection, but the idea is there. (I really like the pullcord start!)
So the technology's out there, who knows what we might see next??
