Just found this on some site. Apparently it's a 2 stroke but no idea what bits it took to make this.

84 RZ. Half naked, SpecIIs, GSXR front end, FZ swingarm, SV rear wheel, trail tech speedo/tach
I have an answer courtesy of David Howard
The bike is a Fior, built in FR by Claude Fior. It was raced in the European 500 championships in the early 80s. The bike is noteworthy for girder front forks, which allowed for very late braking and the maintenance of the fork's rake and trail under braking made this a superb handling bike. The engine is the NSR 500 triple (my next guess).

I have an update. The engine is actually a TZ500 inline 4 reverse cyl. It's hard to tell from the pic, but there are 3 chambers exiting under the seat.
Here's a better pic: http://www.servimg.com/image%20preview. ... u=10006745
If you look closely you can see all 4 silencers and 4 carbs.
Here's the same bike with a Honda V3 with all 3 chambers going straight back: http://www.europark.com/rmac/ny-fio500p1988.htm

Edit: I can't get that first link to paste because of the space bet. image and preview, so you'll have to type it in yourself; believe me, it's worth it.

Front suspension is like a car with the wheel turned 90 degrees, the curved lower piece connecting to the engine has a matching one on the other side and they serve as the lower control arms. The larger piece connected to it is the upright to which carries the steering bearings and has the bottom of the damper attached to it ahead of the carbs. The handle bars are fastened to the top of the rigid fork.Look hard at the suspension and steering.Discuss.

The bars are not attached to the fork itself.They are mounted on the upper "control arm" and connected by linkage for steering.If you look directly below the clip-on end you can see part of the steering linkage.This is BMW's Duolever fork.Claude Fior holds three patents on this however he died in 2001.I'm not clear on how Hossack got ahold of it but it's mentioned on Wiki (not reliable) as the Hossack/Fior.I like how it's a monocoque/stressed member chassis.Take a real good look at the rear suspension.
I really don't know why the manufacturers haven't picked up on this technology.It has a lot to offer especially now with all the power we can access.

engine is Tz inline 4
and the author of this beautiful project was Fior (nickname Pif)
he was a frech engineer that made several motorcycle chassis with unconventional front end, he made also some maountain bikes, so strange too.
he started to work on forkless frame with a 250 cc TZ engine
and after he make this 500 inline four and a V3 RS 500 honda powered.
one of these bike was ride by Marco Gentile, a switzerland rider in 1989
beatuiful time when a simply engineer can make a gp machine
with most innovative technology and obtain a honest result too![:smt002](./images/smilies/002.gif)
