Best for: Designed as a sport-touring-leaning supersport, blending brisk in-line four performance with a slightly more relaxed chassis setup than a full-blown race replica.
Built for: A characterful late-90s/early-2000s inline-four sport machine that rewards revs with a smooth, linear power delivery and confident, stable cornering manners.
Not ideal for: Not ideal for complete beginners seeking an upright, low-effort commuter, nor for riders wanting genuine long-distance touring comfort or any off-road capability.

Scores are derived from the spec sheet using the same model across every bike, so they compare like for like.
