Consider the Gnome et RHONE 800 AX motorcycle to be the steroid laden creation of its civilian brother. They were built for exclusive use by the French Army in 1938. Powered by a flat twin 750 cc engine that drove the rear wheel, navigation was easy so long as a sidecar was not attached. However, since these were used primarily for communication purposes, that meant there usually was a sidecar attached. This was problematic because the engine did not power the sidecar wheel, just the rear motorcycle tire. Driving was tricky, but at least you got a left arm workout from trying to keep the bike on the road!
