Steel trellis frame w/ the engine as a stressed member... now that is new!

Jokes aside, this should be interesting. a 500cc 2-smoker could put down a lot of power and weigh very little. The X pattern's interesting.

I don't get it? The crankshaft appears to move around, how does that work?

It's a sleeve valve two stroke

So it's sort of like old Aircraft engines?

Neat, kind of a take on a Wankel.

Sorta. You're probably thinking of a rotary or radial engine (look similar when off - but very different in operation). But the ones on planes were 4 strokes though sleeve valves were used in them

Radial engine cut away

True that, radial engines that go up to to like 10 cylinders

Older Russian warships used radials for power that had over a hundred cylinders!

100 cylinders but i am certain in a few banks. you couldn't fit too many in a single bank. remember the F4U Corsair or the Baa Baa Black Sheep? It had 18 cylinders and it was packed.

Yeah lots of banks.

The Corsairs 'Double Wasp' had 18 cylinders

Ahh, the rotary! The mighty little engine that could:

powerful, smooth, seamless, sexy! It's why I still have my twin turbo 94 RX7 after 14 years, well, that and it is drop dead gorgeous!

Actually - I was talking about the original rotary - as opposed to a Wakle. The old school rotarys - the whole f'ing engine turned. Think WWI, not Mazda

edit - found a video. Kinda scary buggers
