How it rides
Editorial estimate from the spec sheet - not lab tested- Best for
- Built as a high-performance sport tourer, it excels at fast, twisty road riding and long-distance runs where speed and precision matter more than outright comfort.
- Built for
- Exotic, boutique, and unapologetically powerful, this bike suits riders who want a rare American-made V4 with race-bred components and a strong sense of individuality.
- Not ideal for
- This is not the right bike for off-road exploration, absolute beginners, or riders prioritizing plush all-day comfort over sporting performance.
Scores are derived from the spec sheet using the same model across every bike, so they compare like for like.
