Very few automobile mfgrs use direct injection as of yet, and no m/c mfgrs that I know of. Not even that many auto racing series allow it, to my knowledge. So it's got to be hugely expensive to develop, especially for a start-up m/c mfgr. Hope they have plenty of capital.
Anyway, sounds intriguing, and too expensive for me. Hope they can make it work.
