This motorcycle is unique because it’s not quite a motorcycle, yet not a sidecar bike either. However, it’s DEFINITELY a military bike. Made famous by Italian manufacturer Moto Guzzi in 1940, it had a broad battle history of usage due to its functionality. The Trialce was capable of transporting soldiers, weapons and just about any other load. In addition, it was fixed with an amazing anti-aircraft gun, and had a 500 cc engine that spit out a whopping 13.2 hp. This meant soldiers could speed along at a max speed of 45 mph. It was only produced for two years, yet, they made quite a bit of them. In total, 1,741 units were produced.
