How it rides
Editorial estimate from the spec sheet - not lab tested- Best for
- It is built as a lightweight, characterful allrounder for spirited backroad riding rather than outright speed or long-distance hauling.
- Built for
- Expect a punchy, vibration-rich big-single feel with strong torque low down and an engaging, raw mechanical personality typical of 90s thumper-based sportbikes.
- Not ideal for
- It is not a good fit for riders wanting plush comfort, serious two-up touring, or high-speed motorway cruising.
Scores are derived from the spec sheet using the same model across every bike, so they compare like for like.
