nzralphy Posted March 16, 2010 Report Share Posted March 16, 2010 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 !..... Quote Link to comment Share on other sites More sharing options...

houseape1000 Posted March 16, 2010 Report Share Posted March 16, 2010 just don't replace big or small end bearings, you'll soon have an oval piston ! Quote Link to comment Share on other sites More sharing options...
jse Posted March 16, 2010 Report Share Posted March 16, 2010 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.........

treevor Posted March 16, 2010 Report Share Posted March 16, 2010 Should sell, its only done 1360 miles Quote Link to comment Share on other sites More sharing options...
jse Posted March 16, 2010 Report Share Posted March 16, 2010 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...........

toofasttim Posted March 16, 2010 Report Share Posted March 16, 2010 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. Quote Link to comment Share on other sites More sharing options...
jse Posted March 17, 2010 Report Share Posted March 17, 2010 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 Quote Link to comment Share on other sites More sharing options...
lightfeet Posted March 28, 2010 Report Share Posted March 28, 2010 (edited) 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, 2010 by Lightfeet Quote Link to comment Share on other sites More sharing options...
pete_scorpa3 Posted March 28, 2010 Report Share Posted March 28, 2010 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 Quote Link to comment Share on other sites More sharing options...
