Yamaha Golf Car G23A UMAX Medium Duty I
Yamaha Golf Car publish no page we could find for this model: Checked Yamaha's current golf car lineup page (yamahagolfcar.com/golf-car) on 28 Sep 2026. It lists DRIVE² PTV QuieTech EFI/PowerTech AC/PowerTech LI, UMAX EFI/AC/LI, UMAX Rally Sport, UMAX Rally 2+2, UMAX Rally Sport 2+2, UMAX 4 EFI/LI, UMAX 4 Rally Sport, DRIVE² FLEET, UMAX Rangepicker, UMAX Bistro and Adventurer Super Hauler EFI/AC/LI trims, but no "G22", "G23", "G27", "G28" model code and no "UMAX Light Duty"/"UMAX Medium Duty" trim anywhere. This row's own identity comes from its 2004-era owner's manual, whose printed heading does not have to match the current marketing lineup; the absence here is not treated as evidence this machine has been discontinued. Checked 28 September 2026.
