How it rides
Editorial estimate from the spec sheet - not lab tested- Best for
- Built primarily as a high-speed, high-drama sport-touring statement bike rather than a nimble corner-carver or off-road machine.
- Built for
- A charismatic, exotic-feeling machine whose six-cylinder soundtrack and smooth power delivery reward riders who value engineering theater and open-road cruising over sharp handling.
- Not ideal for
- Not a good fit for beginners, off-road riders, or anyone wanting a light, flickable bike for tight city streets and technical corners.
Scores are derived from the spec sheet using the same model across every bike, so they compare like for like.
