Any chance of it being in the 2015 international supershow? would pay to see this..

998cm3. I thought it was a 750...
Tell that to Bombardier with their direct injection E-TEC 800R
Comparing the near impossible to acquire exotics from Kawasaki and Ducati really shows the beauty of the Italian design. I never will have to choose but if I did the Superleggera would be my pick.

I know about those. The emission standards for outboard motors and snowmobiles are an order of magnitude more lenient than Euro 4 (current motorcycle requirement) and Euro 5 (coming soon). The European emission regulations are much more stringent than the (outdated) North American motorcycle emission standards. The bike has to be built to conform to the most stringent standard that will be in effect through its production lifetime, and that will be Euro 5.
The direct-injection two-stroke systems have the following emission-related difficulties:
- Catalyst warm-up (affects cold start and warm-up HC emissions) because the exhaust temperature tends to be low due to higher dilution. In-cylinder fuel distribution at light engine load (e.g. idle) tends to have some areas too lean or too diluted with recirculated exhaust to burn, but enough to contribute to HC emissions that the not-warmed-up catalyst can't treat. 4-stroke engine running stoichiometric with minimal EGR doesn't have this problem.
- NOx, because fresh air short-circuiting across the piston plus the intent to run the engine lean for fuel economy causes too much oxygen in the exhaust stream to allow a 3-way catalyst to reduce NOx. The engine-out NOx tends to be fairly low because of inherent exhaust recirculation, but not low enough. There's no known way to meet Euro 5 NOx standards without exhaust after-treatment of some sort.
- Particulate matter ... because the piston rings have to be lubricated, and every time the piston rings cross one of the ports, a bit of the lubricating oil either gets into the intake air or out the exhaust pipe where hopefully the catalyst can get it, but lube oil doesn't get dealt with as well as fuel does.

All of those production-quantity numbers are idle speculation.
The 800lb gorilla in the room is whether this bike is already banned from most insurers.
I agree. I've already lost interest in this bike.damn its ugly, and I'm a kawi fan...
I guess designers of the bike watched too many transformer movies.
