  • What an absolutely horrible quality vid! Are there any newer, better vids out to promote what looks like an innovative product. This motorcycle needs to be promoted thru real-world feature reliability and performance demonstrations. Common sense public relations stuff. I'd like to see more.

  • The video is really bad so do another fast, and people will take you more seriously, This is a good motor so don't mess it up with a bad video.

  • For Christ's sake... the added benefits of rotary valves are high compression and higher engine speeds. Why would your first motorcycle demo be in a chopper?

  • Nothing new Ducati the Italian motorcycle co had a rotary valve engine back in the 70s they called it the decible engine......

  • This thing sounds like a turkey when it passes by.

  • Looks like video out of the 1970's

  • I read about these guys in like Car and Driver years ago I wonder what ever happened to em. They said you could put these on a stock Mustang Gt and go from 215HP to like 400 back in 2000 or so.

  • absolutely horrible video no point ,,horrible sound and absolutely no clear message!! Couple of morons with a cell phone video I think.

  • Great idea and product -- but lacking in message delivery and marketing. If this company would start selling heads for common engines as replacement, instead of new engines overall, they could probably break into the market easier.

  • If I had a chaff cutter that sounded like that, I'd dump it.. The video quality is bloody woeful too.

  • @sranjesuper how bout no. there's already to much electronic shit on cars.

  • A subsiderary
