The only way Dorna are likely to get a 600cc class off the ground is with bespoke engines/chassis, unless there's an awful lot of money in it for Flammini. Should Dorna try to go down the production spec motor route, Flammini will have Dorna in the courts straight away. So it would need to be an all-new motor or motors.
Honda, to me, are the most likely supplier of a spec motor. Of course if one major manufacturer is producing race motors for Moto2, we'd quite reasonably expect to see nil involvement from any other manufacturer - and a flurry of activity in the bespoke chassis manufacturers arena. Illmor, Harris, Spondon, Bimota (although I don't believe Bimota has every built a Honda-powered bike before?), Over and other companies would probably at least consider building bikes to take the spec motor. Even start-ups like MotoCzycz could potentially get involved in Moto2 under this scenario. So it could become a fairly interesting class from a chassis perspective.
I also can't at this point see why you couldn't take a current M1 chassis and slot a spec Moto2 engine into it...
