1992 Honda NR750 - Approved

The 1992 Honda NR was a 750cc street version of their oval piston bikes. Yes oval pistons, an interesting looking thing. Kind of like a loaf of bread. Interesting shape.  The bike was about $50k, and they made about 300. It meets the requirements for Show or Display.

This was followed during the 1980s by a 750cc endurance racer version known as the NR750. The oval piston concept allowed for eight valves per cylinder which generated more power due to the increased air/fuel mixture throughput and compression. In 1992 Honda produced around 300 street versions of a 750cc model, the NR (often mistakenly referred to as the NR750), with a 90-degree V angle. Whereas the NR500 had used an oval piston with straight sides, the road going NR750 used an elliptical piston with curved long sides. The bike became the most expensive production bike at the time when it was selling for $50,000 and with the rarity, nowadays they rarely change hands.
