There's nothing new here. Frameless motorcycles are all around you: they're called BMW R1100s. And so are Vincents, though you don't see so many of those these days. The so-called 'radical' aerodynamics amount to putting the rider behind the engine to reduce frontal area, which simply means lengthening the wheelbase and spreading the weight of engine and rider along it, which will adversely affect manoeuvrability by making it difficult to achieve centralisation of mass, though most people who buy one (if it ever reaches production) won't ride it hard enough to notice. Pitching, or moments of inertia about the transverse axis, will be the issue. As for the brakes, well, they're just off a Buell, and the torsion springing was last tried on Suzuki's unloved TL1000S, though back in the fifties it was popular with several mid-weight European bikes. The double chain run final transmission is hopeless, though, a real mess both aesthetically and otherwise, and it shows that they just haven't thought about it properly. They want the rider's heels on the rear axle, almost, and that means tucking the chain out of the way. The real answer would be to design the engine so that the drive comes out nearer the middle of the gearbox, but I guess they're using a donor engine and can't afford to design their own motor. BMW's piggy-back transmission and high-exit belt drive on the new F800 almost solves the problem for them, but it seems they ignored that. Nope, sorry, but this is another superbike that will stay on the drawing board.
