Best for: A muscular, style-focused naked bike meant for spirited street riding and weekend backroad blasts rather than track days or long-haul touring.
Built for: Torquey, distinctive, and mechanically charismatic, with the boxer's low-end pull and shaft drive giving it a relaxed, unmistakable personality rather than razor-sharp aggression.
Not ideal for: Not a good fit for riders seeking off-road capability, a passenger-friendly plush tourer, or cutting-edge outright acceleration.
