Um, one OPOC engine motorcycle, please.

You have to get to the third paragraph before you discover that the engine he is holding in the picture puts out 75hp.  The website says "produces more than 1 hp per pound of engine weight"
It is a two stroke but they claim that they can scavenge 90% of the fuel, which evidently is on par with a 4-stroke.  I'd rock a diesel motorcycle.  Pretty interesting stuff:

Looks fascinating, Hopefully they can get the Technology to work, Interesting they have Bill Gates investing in the Design/Engine/Company.

Could be very interesting!

There are diesel motorcycles already, but the one I know about isn't available in the US and makes less than 10% of the claimed horsepower of the OPOC motor...

664 ft/lbs?!?

IMAGINE THE BURN-OUTS!!!!! 


(which can be translated to, I'm down.  Please ship the motor to:.....)

wonder if the can make a 'single' cylinder for motocycle use with that design. would be even more compact.

[Latinbalar]

That would be nice the motor could be mounted down low and that would be one nimble little bike.

Without the weight of an engine, the bike would wheely pretty easily.

Large ship engines are generally 2 stroke diesels, and they are very efficient. I believe this guy is really on to something, especially the opposed piston design which was also used in Doxford Marine engines.

Wait wait - found something along the same lines

Except this one is WAY cooler because this one is a DESMO

I want to see a multi cylinder version with a couple turbos in a Le Mans car.
