A simple twist and go CVT auto-transmission with extra twist in the form of a punchy 492.7cc four-stroke single. Not a cheap Chinese effort but a modern 4-valve, liquid-cooled emissions compliant unit. To be honest the steel tubular frame and running gear is a lot to pull and acceleration isn’t the best when faced with a hill. But from the lights it’ll leave cars standing and go on to sit at 70mph all day every day.
