2026 Suzuki KingQuad 400FSi
The numbers
Where the price sits
A comparable set is anchored on this machine's odometer, and this listing does not publish one. There may well be machines like it on the board — there is just no way to line this one up against them. The ask is shown on its own instead.
A comparable is the same make, model, year and trim, within 3,999 miles of this odometer and 500 miles of this dealer. Unpriced listings are ignored, this one is excluded, and a dealer posting the same machine twice counts once.
