2027 KTM 300 SX
The numbers
Where the price sits
1 listing matches this machine, and the rule wants 3 before it will call anything a market — a median off fewer is their average. 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.
