Best for: Built primarily for spirited road riding and canyon carving, with genuine track-day capability thanks to its aluminum perimeter frame and sharp geometry.
Built for: The 955i in-line three delivers a distinctive, torque-rich growl and mid-range punch that gives it a more characterful feel than typical four-cylinder sport rivals.
Not ideal for: This is not the right bike for new riders, tall touring distances with a passenger, or anyone seeking a relaxed, upright commuting experience.
