24. Norton 633

Next up is the Norton 633, which was a more powerful version of the model 16H we just profiled. Even better, the Norton 633 could be outfitted with a sidecar, and held distinction as being the only British motorcycle capable of providing drive power to the side car wheel itself. And speaking of sidecars, this was no normal civilian motorcycle sidecar. The Norton 633 sidecar was essentially one big open box with zero protection from the elements. Yet, the design was intentional. The sidecar contained a rack suitable for mounting a BREN light machine gun and could also be used as a proper weapons platform when need be.
