Don't hold your breath on a naked version. I suspect that the next version will be a less ex$pen$ive, fully faired model. Hiding the radiators and what I suspect is a pretty large muffler/cat is going to be tough without bodywork.
I'm surprised that nobody mentioned the dual air scoops for the front caliper. If that's not a "Buell" answer to the question of brakes, I don't know what is. EB is determined to use ZTL-type brakes, and given the anticipated performance of this bike, had to channel air to the caliper to reduce the chance of heat-induced rotor warp.
Personally, I'm relieved that the lines are a little more orthodox. The broad, squat front view of the 1125R never worked for me. I suspect that this bike has seen some wind-tunnel time, or at least a bunch of CAD time, and that's an aerodynamically efficient shape.
As to the oil in swingarm, while it's clever, it does introduce some complexity and vulnerability to failure that's probably not acceptable for a race bike. The Rotax is a dry sump motor, IIRC, so there's an oil tank somewhere.
Sadly, unless by some miracle I see one at the track or at the IMS show, pix are all I'm gonna get.
