How it rides
Editorial estimate from the spec sheet - not lab tested- Best for
- Designed as a fun, torquey street naked for spirited commuting and weekend backroad rides rather than outright racing or long-distance touring.
- Built for
- The 90-degree V-twin gives it a raw, torque-driven feel with strong low-to-mid RPM pull and a throaty exhaust note that feels more premium than its price suggests.
- Not ideal for
- Not the right choice for riders seeking off-road capability, plush long-haul touring comfort, or class-leading top-speed performance.
Scores are derived from the spec sheet using the same model across every bike, so they compare like for like.
