March 16, 201016 yr 'Bleedin' hell! I would have guessed about 35,000 squids. Kinda puts Vestys Sherpa into perspective.
March 16, 201016 yr 105,000 ! Probably ok if there was no recession, but not sure now. I understand that there was only 4 or 5 into the UK so it may not be unreasonable. AND how the hell did they make oval piston rings that sealed on an oval bore!!!!! That alone is worth 105k. I'd buy an oval piston trials bike !.....

March 16, 201016 yr What are the benefits to an oval piston engine? As I understood, the NR750 (actually the "RC40") was built to comply with international roadracing rules that limited the number of cylinders the engine could have. The NR's V-4 is essentially a V-8 with conjoined cylinders. The engine had 8 valves per cylinder (and 2 plugs, 2 connecting rods, 2 injectors etc.), which addressed the problem of reduced volumetric effeciency with larger valves in larger cylinders. The bike was not that successful as a racer, but sure showcased Honda's ability to "build it because we can" corporate philosophy. There are a few of us still around that remember the legendary RC166 250/6. I would imagine that parts are quite dear at one's local Honda dealer......... Jon
March 16, 201016 yr Should sell, its only done 1360 miles I would think so. They are fairly rare, I think only about 200 were made. The NR is the later street version of the race bike, which did not dethrone the two-strokes as intended. It didn't do much on the race track but it did cement Honda's reputation as a technological giant at the time. I already talked to my wife about us making an "investment in motorcycle engineering history" that I could proudly display in my shop. She said "fugitdaboudit" in no uncertain terms........... Jon
March 16, 201016 yr The bike was not that successful as a racer, It was very successful in endurance racing. It's grand prix career was ..um..spectacularly unsuccessful.
March 17, 201016 yr It was very successful in endurance racing. It's grand prix career was ..um..spectacularly unsuccessful. Yea, you're right, I forgot about that, they did quite well. I was thinking GP, but the bike was a very good endurance racer. Maybe I can con my wife into buying a historic endurance racer. Hmmmm, probably not, darn........ Jon
March 28, 201016 yr Actually it was the NR500 Race bike that used "Oval" pistons, the Production bike NR 750 used elliptical pistons, nit picky I know but there is a difference The pistons are oblong shaped, but with rounded-off corners Edited March 28, 201016 yr by Lightfeet
March 28, 201016 yr The fella in the listing looks like he's riding it on a wet public road, in front of a bus without a helmet on. Strange way to treat a
March 30, 201016 yr Ah but could you afford an oval pistoned trials bike? It's a common feature on a Sherco
