I gather they've got a long history of making top end gas powered racing bikes.
He had this to say:
I remember feeling sad for weeks when I learned 2-strokes were on their way out but my mourning was short lived once I laid eyes on their replacements - the mighty 4-stroke 990’s. While I am NOT claiming ICE to be out or electric to be the “new” MotoGP, I am stating that this is a very magical power source. The torque deliver is what every engine designer and tuner tries to mimic. In ICE, this can only be achieve by adding layers of electronics; we now just have the electronics!
MotoCzysz is not just pursuing an electric motorcycle (that sounds like such a slow downer) but a bigger concept using electric drives - the “Digital Superbike”. The Digital Superbike, like your computer, has “open architecture” and can be upgraded and reconfigured. This is definitely an industry first and may be a major paradigm shift in the way people buy and own motorcycles. The sound of progress is building in volume…keep your ears open.
And they posted a video of dynomemeter testing of their bike: http://www.motoczysz.com/videos/e1_dyno.html
