Best for
Built as a straight-line power statement and drag-strip curiosity rather than a corner-carving sportbike, despite its Sport category label.
Built for
A brash, spectacle-driven muscle bike that trades agility and refinement for raw, thunderous V8 acceleration and show-stopping presence.
Not ideal for
This is not the right choice for new riders, tight urban commuting, off-road use, or anyone wanting nimble, flickable cornering manners.

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