I hope my memory isn't faulty, but I seem to recall that before Brammo decided to build electric motorcycles, they were thinking of electrifying an Ariel Atom (and I think they actually did produce a prototype). When I read that, I wondered what an Ariel Atom was. Now I know. Top Gear, the funny and fun British high-performance car show tested an Ariel Atom V8 in their latest episode and raced it on the same track (at the same time) against a new BMW S1000RR street-legal superbike. Here is the link to the 12-minute video of the Top Gear segment. I note that Top Gear has retained a new Stig (which is their anonymous professional race car driver) :
If I was wrong about the historical link between Brammo and the Ariel Atom, I apologize. But it is still a fun episode to watch. If I was right, you can imagine what an electric version of the Atom might have been like.
