ARCH Substance 171

The ARCH Substance 171 is a motorcycle being developed by ARCH.

Overview
The Substance 171 is built with one aim in mind - to achieve the impossible. Crafted from an intricate blend of carbon fiber, aluminium and cured leather, the ARCH Substance rests on an ultralight, noncellular frame, giving it an agility and manoeuvrability that - powered by a CHOOH2-combustible engine - allows it to reach speeds never before imagined.
