How it rides
Editorial estimate from the spec sheet - not lab tested- Best for
- Built primarily as a stylish, easygoing modern classic for commuting and weekend rides rather than outright performance or long-distance touring.
- Built for
- A torquey, characterful parallel-twin roadster that prioritizes smooth, tractable real-world power and classic British styling over outright speed.
- Not ideal for
- Not the right choice for riders chasing high-speed thrills, serious off-road capability, or a dedicated long-haul touring setup with passenger comfort and wind protection.
Scores are derived from the spec sheet using the same model across every bike, so they compare like for like.
