Rider Profile

Best For	This rotary-engined Norton rewards riders who already understand the unique power delivery and rev character of a Wankel engine, so some prior riding experience is recommended.
Purpose	It suits riders who want a distinctive, mechanically unusual sport-tourer for spirited road riding rather than commuting or racing.
Rider Fit	At a moderate 262 kg with a naked-classic riding position, it is manageable for most riders of average height and strength without demanding excessive muscle.
Character	The bike has a smooth, turbine-like power delivery typical of Wankel engines paired with classic 1990s British roadster styling, giving it a quirky, characterful personality.
Not Ideal For	It is not the right choice for riders seeking off-road capability, modern electronics, or long-distance touring comfort with passenger amenities.
