The 2023 KTM 390 Adventure keeps the 373 cc trellis-framed layout of the 2022 bike but adds tougher black anodised aluminium spoked wheels (19 in front, 17 in rear) alongside a cast-wheel version. It has a new colour and graphics scheme, and the electronics carry over with ride-by-wire, traction control, cornering ABS and an off-road ABS mode. It is pitched at commuting, light off-road riding and weekend touring.
