Norton Rotary Development (9): Norton Prototypes

Thanks to the same customer who enabled us to build the first "NRS588", we could eventually build the definitive Commander. As can be gathered from our remarks on the production P52 and P53, we think this was one of the best touring motorcycles of its time. However, it was lacking in some departments, due to having been designed as a Police motorcycle. As such, it was developed to be sold at a budget price. This was o.k. as far as public service went, but a civilian version should have differed in some major components, as a private owner could be expected to pay a higher price and, therefore, the civilan version could have had a higher specification. This did not happen, as time and money for such an exercise were not available. Neither was, probably, the awareness of a discerning public!

The following improvements are but a fraction of what went into the bike:
