Best for: Built as a torque-monster cruiser for relaxed highway cruising and effortless roll-on acceleration rather than for cornering or track work.
Built for: The huge 2.3-liter inline-triple gives it a unique character, dominated by massive torque delivery, a deep exhaust growl, and a stately, unhurried demeanor.
Not ideal for: This is not the bike for riders seeking agility, off-road capability, or a lightweight, flickable ride through twisty roads.

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