How it rides
Editorial estimate from the spec sheet - not lab tested- Best for
- Best suited to relaxed street riding, weekend cruising, and short trips rather than aggressive sport riding or long-haul touring.
- Built for
- A laid-back, air-cooled V-twin roadster that favors smooth torque delivery and classic naked-bike charm over sharp handling or high-revving excitement.
- Not ideal for
- Not a good fit for riders wanting sharp cornering agility, high top-end power, or serious off-road capability.
Scores are derived from the spec sheet using the same model across every bike, so they compare like for like.
