Honda NR750 Motorcycle Pin
This is a metal clothing pin/badge of the most desirable and collectible model, the NC40 or NR750N. Honda's V-four motorcycle engine series NR started in 1979 and produced several racing bikes, as well as a road-going model (NR750) that was the most expensive production bike of its time. Have you seen the price of the bikes now? The pin fastens via a butterfly clutch on the back - see pictures for more details.
