Best for: Built as a straight-line, boulevard-cruising showpiece powered by a genuine small-block V8, it exists to deliver brute acceleration and spectacle rather than cornering finesse.
Built for: It's a bold, attention-grabbing muscle cruiser with a thunderous V8 soundtrack, built for riders who want raw power and novelty over agility or refinement.
Not ideal for: This is not the bike for new riders, tight twisty roads, off-road use, or anyone wanting a light, nimble, or subtle motorcycle.

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