Ok, here goes...Honda NR750. A very rare bit of unobtainium produced as a tech
item for very well to do bike enthusists...the very few examples produced (under
200 worldwide) commanded $60,000 or more. Key highlight of this motorcycle was
it's engine, a liquid cooled, DOHC V4 with gear driven camshafts. But the real
technological tour de force laid within its combustion chambers and
cylinders....four OVAL pistons (draw two cicles next to each other and then
connect them with lines top and bottom) and you'll have an idea how the pistons
were shaped. TWO titanium connecting rods per piston were operated off an
intricate machined steel crankshaft. Each cylinder head contained EIGHT valves
with a narrow combined angle in a pentroof (hemispherical) combustion chamber
designed to create rapid flame propogation through the fuel mixture, which was
sprayed into the intake ports via Honda's PGM fuel injection system using TWO
Denso injectors per cylinder. This engine grew out of Honda's groundbreaking
1980's NR500 Grandprix bike, which used this technology in an attempt to compete
against the very fast 4 cyclinder two-strokes dominating the circuits of the
day. If you haven't figured it out yet, looking at the engine design and
configuration, you'll discover that this was a thinly disguised V8....Honda
neatly sidestepped the FIM rules that stated 500cc GP engines could not have
more than 4 cylinders. I hope this helps!

Correction to the above, addendum;
Each COMBUSTION CHAMBER contained EIGHT valves, for a total of 32 valves! Neat,
Huh?

By the way, I didn't plagiarize this copy from any source...I just happened to
be "around" this project when it was unveiled.

Oval-Piston Technology
Debuting in Honda's NR500 racebike, oval pistons eventually found their way into
production in Honda's exotic NR750.

Sorry, thumbnail of the engine didn't show up in the above post. I post some
pics of the bike and its engine soon.

fossil_digger, I think it is a low-orbit launch vehicle, from what this 90130
tells us.

you had me to believe that honda was going to reintroduce the nr - pssh - im
quite educated on these matters

Low orbit indeed! I actually had a chance to ride one of the pre-production
bikes, and Honda brought in only a few hand built production examples to the US
which were snapped up by (wealthy) collectors. The exhaust note is
unbelieveable...a combination of a deep bass drone that turns into a wicked
raspy shriek at around 12,500 rpm that you can feel in your bones!

15526, Fossil Digger's post of the bike above is a customized NR. Even if Honda
would build this bike again, albeit with some aspects of its design modernized
to 2006 standards, the bike's cost would be in the $100,000+ range.
These were all hand built by an HRC team dedicated only to it's construction.

whassup w/those tires? they're not metal......

This is a customized NR, and I believe that the bike was "prepared"
to create an art image. This also has all the earmarks of being a digitally
manipulated picture.

thought so. had to be, but that's what caught my eye right off.
