BMW Unveils Vision K18 Concept Bike With 1,800cc Inline-Six

The one-off showpiece signals where BMW may take its inline-six touring design.

Overview

  • BMW Motorrad revealed the Vision K18 at the Concorso d’Eleganza Villa d’Este on Lake Como as a single-build concept rather than a production model.
  • The design centers on a 1,800cc inline-six engine that BMW presents as a brand statement and the visual core of the motorcycle.
  • The long, low silhouette draws on high-speed aircraft like the Concorde, with a pointed nose and retro‑futurist cues that stress motion even at a standstill.
  • A recurring “six” theme runs through the bike with six LED lights up front, six intake tracts, and six exhaust outlets integrated into the tail.
  • Hand‑formed aluminum and forged‑carbon bodywork include a reported seamless side panel over two meters long, and the concept uses hydraulically lowerable suspension to achieve its low stance.
