Best for: Built primarily for spirited canyon carving and track-day performance, with the 636cc engine giving stronger midrange than a typical 600.
Built for: A precise, revvy in-line four supersport that rewards aggressive throttle inputs and confident cornering lines.
Not ideal for: Not a good fit for riders wanting an upright, relaxed commuter or long-distance tourer, or for any off-road use.
