Between the 170’s and 80’s, Honda tried to slow the onset of two-stroke engines at world championship level by creating the NR500: a four-stroke, V4 engine with oval pistons and 32 valves that had 130 hp and a maximum power of 20,000 rpm.
After this unsuccessful experiment, Honda created a road superbike at 750cc so evolved that it was to be considered the most revolutionary and technological of all time.
The bike was called the NR750 and when presented back in 1992, it had a cost of about 50,000 dollars.
The adventurous four cylinder was a high performance, concentrated solution of innovative technology, where the fork, chassis and instrumentation were all a monument to this innovation.
The revolutionary pistons were set to guarantee higher performance.
The ample surface, obtained thanks to the elongated piston design, allowed for the use of a greater number of pistons, increasing the aspiration capacity of the cylinders and making the V4 similar to a V8.
The NR750 road version didn’t have such an exaggerated power, though, with 130 hp at about 14,000 rpm.
The NR750 was built in just 300 examples and seeing it on the road, especially now, is a rare event indeed.
But thanks to a little modern technology, we can hear the engine of this incredible bike and wonder what it must have been like to be on board this two-wheel missile.
