I've been following the development of this engine for a couple of years and could see it as superior to the Rotax 582 on many levels. Any thoughts on this?

"With an industry-first design that’s compact and lightweight (under 50 pounds), this 400-class (397cc) two-stroke single-cylinder engine with electronic fuel injection and 3-stage exhaust port modifier (power valve) system delivers impressive throttle response and surprising engine performance. Rated at 65+ HP-, a counter-balance shaft eliminates most engine vibration".
