How about the Fueling W3 2458cc machine?, never heard of them before. (not the same one)

4 stroke NR 

pistons weren’t round but oval

shimmering, colour-shifting windscreen

only major victory @ Calder 

mirror in the dash to show the LCD display at “infinity” so the rider didn’t have to refocus when checking the instruments

digital speedo unique for the time

Well, good spotting there PB. Take my hat off to ya.

It sure is not a pretty bike but loaded with high tech stuff of the day. Fancy it selling for over 100 grand in todays dollars when released.

I do remember the oval piston aspect of it, though don't think I ever saw the bike at the time.

Oval pistons never really caught on did they, must've been a bugger to hone the bores if they were oval...haha.

Anyway here is the blurb lifted from the auction site regarding the bike.

Kawasaki, Yamaha, Suzuki and Honda were locked into a technological battle of the titans and produced a torrent of increasingly sophisticated and powerful motorcycles in the 1980s and 1990s. The 1992 Honda NR750 rode above all as the ultimate power in the motorcycle technology universe and was the most exotic and expensive production motorcycle of its time. Honda's chariot of the future sold for over $100,000 in today's dollars, and only a few hundred were handcrafted into reality. The NR750 was bristling with motorcycle technology firsts and is the only production motorcycle powered by an oval-piston V-4 engine born from a potentially advantageous interpretation of racing regulations. After a 12-year hiatus, Honda returned to Grand Prix racing in 1979 with its code name "0X" four-stroke V-4 NR500 against a field of two-stroke contenders. As a two-stroke engine can make twice as much power as a four-stroke engine at the same RPM and rules limited engines to four pistons, the "0X" used four elongated oval pistons with two connecting rods and twin-plug 8-valve heads that effectively turned the V-4 into a V-8. The "0X" proved troublesome, and Honda transitioned to a two-stroke V-3 for 1983, but subsequent "3X" technology gave the 1992 NR750 its 750cc oval-piston quad camshaft 32-valve V-4 beating heart. With PGM-FI fuel injection and CPU controlled ignition timing, the V-4 delivered a linear 125 HP at 15,000 RPM. Upside-down cartridge forks, a single-sided rear swingarm and side-mounted radiators were futuristic then and new. Mitsuyoshi Kohama and the Honda design team brought art and technology together with carbon fiber reinforced bodywork, a color-shifting titanium windscreen coating and the first underseat exhaust on a four-stroke production motorcycle. New and improved means nothing unless it works better than it did before, and NR750 technology is seen on modern motorcycles today.
