Motorcycle specifications HondaNR 750 1992 HRC's absolute

the Honda 750 NR is no longer a motorcycle... it's a technical achievement! A concentrate of know-how, Honda's ultimate motorcycle. The Japanese manufacturer designed it for the purpose of riding, but its real place would be in a glass pyramid capable of defying time. Let's ignore certain materialistic considerations, such as the totally insane price (375,000 bales in 1992), the frightening rate of production (3 units per day) or the number of models built (around 800 are said to have left the factory). 34 models arrived in France. The manufacturer had the good sense to offer each (wealthy) buyer a solid silver Honda key-ring. The NR combines the very best of research - fully adjustable upside-down forks, a single rear arm, a dashboard with every conceivable control dial and digital tachometer, magnesium rims and stainless steel exhausts under the seat. The bubble, to protect the rider from ultraviolet rays, receives a titanium surface treatment similar to that on American F 15s. The all-carbon-fibre fairing is not just ultra-light; it is also aerodynamically advanced, cancelling out the harmful effects of airflow and allowing the NR to glide through the air like a shark through water. But the most talked-about aspect of the NR is its extraordinary oval-piston engine. This is no joke! Each cylinder contains an oval piston that transmits its force to 2 forged titanium connecting rods. The combustion chamber is fed by no less than 8 valves and 2 spark plugs.

Add it all up and you've got a V4 with 8 spark plugs and 32 valves. A cascade of sprockets and PGM-FI fuel injection complete this monument, which will remain on a pedestal forever, with no descendants. At the time, Moto-Journal tester Eric Maurice had the honor of trying it out and appreciating its fantastic suppleness. His only disappointment was: "A very unspectacular engine and a more VFR-style touring-sport orientation, than pure RC 30-style sportiness". In addition to its high-tech appeal (200 patents filed), the NR set 4 world speed records (obtained with a prepared version, lightened to 180 kg and optimized to 155 hp):

- Kilometer rolling start: 299.825 Km/h
- Mile rolling start: 299.788Km/h
- Mile standing start: 221.219Km/h
- 10 Kilometer standing start: 283.851Km/h.

Some elements of the NR have found heirs, such as the rear-indicator lights on the CBR 1100 XX. But this motorcycle remains a dream, a prestigious machine, the fruit of 15 years of research and engineering passion.
