Well, shoot! I knew it was easy, but that was still a quick guess. Good show, mate.

 

I'll bet you would have been much slower if you had found the original pic. teehee

sorry just couldn't find it anywhere lol

A few RZ201’s were hand-made and according to some sources, 1 or 2 are still "hidden" in the factory to be discovered! now that would be something lol

we have 3 years listed for the same motorcycle lol this is what wiky pedia has to sa about it.......................................................................................................................... The so-called Triumph Quadrant (aka "Quadrent") was a "bitsa" designed and built in secret by Doug Hele in 1973.[1] It was a 1,000 cc four-cylinder motorcycle made up from Trident parts (although the camshaft was sourced from outside the factory). Essentially, the fourth cylinder came from grafting on an extra middle crankcase unit; but since the primary chaincase and final drive sprocket could not be relocated, the fourth cylinder protruded on the right hand side of the bike. The top speed was reputedly 125 mph.

Quite why Hele developed this motorcycle is something of a mystery, as the lopsided machine could never have reached production to compete with modern Japanese machines such as the Honda CB750 or the Kawasaki Z1. An inside view is that Hele's efforts in building the Quadrant was a waste of precious resources that (given NVT's precarious status) should have been directed elsewhere

All I know is that the "National Motorcycle Museum" display has a placard that reads "1975". Zoom in on my latest large picture and in the lower right corner, you can read part of the placard, where it says 1975.

so was built in 73 through 74 final testing in 75

then shelved and pulled out later in 78

all very confusing but hears as much history as i could find on it

if anyone wants to know more read on lol ............................................................................ The prototype Quadrant, introduced in 1974, will never enter production. The only prototype built is now on display at the National Museum of Motorcycles Birmingham.

 

 

 

 

 

 

 

In 1974 Denis Poore, the person in charge of the NVT (Norton Villiers Triumph), asks the team to design a quattrocilindri to counter the various four giapponsi. Not having the financial resources to create a project from scratch,Doug Hele, with the help of Alan Barratt and Jack Shemans combines two engines tricilindrici BSA Rocket III (cylinder slightly tilted forward), remove the two side cylinders, and get it the first four-cylinder Triumph 1000cc (987cc bore x stroke 67x70, compression ratio 9.5:1). The crankshaft is constructed by adding an elbow shaft previously used for prototype trecilindri180 ° C.The camshafts, with a profile less stringent than those used on the Trident, are commissioned to Reg Hyde. The rest of the components of the engine is taken from the two-and three-cylinder engines then in production, and suitably adapted to the new use. Power is supplied by a battery of four concentric Amal carburetors 27mm and the exhaust system is derived from the Trident T160.

 

 

 

 

 

The new four-cylinder engine is mounted in the frame previously used to house the prototype three-cylinder engine with overhead camshaft. The rest of the bodywork is obviously taken verbatim from BSA Rocket 3 MY1972: to minimize the cost of the project fact technicians Meriden trying to use as much as possible components already in production

The prototype "Quadrant" photographed in 1974 -

 

 

 

In January 1975 the new bike took his first steps with the tester Neil Coombes at the MIRA circuit. In the first practice reaches205 km / h, 20km / h more than the Trident, while maintaining a maximum speed of safety equal to 7000 rev / min

 

 

 

The new "four" English was the logical evolution of the 750cc three-cylinder Trident and, according to initial plans of Poor, would have to fight the Japanese competition. After a warm welcome by the management NVT before the project was abandoned due to the high investment needed for the production and the decision to divert scarce resources to other priority projects.

 

The Quadrant would still not arrived in the market before 1977, the year in which the Japanese competition was already the second evolution of modern sport, and in this context it would be a niche bike that he could not change the history of English.

 

The prototype is being sold in Quadrant 1978Roy Richards the future founder of the National Motorcycle Museum in Birmingham. In 1979 Richards from the task of restoringthe Quadrant to Hugie Hancox (former coach Triumph). The prototype was in a state of disrepair, it was painted and missing logos and names on the occasion of the restoration you decide to apply the logos on the tank and side panels. The bike was restored in time for the 1983 years of the inauguration of the museum in Birmingham.

With the arrival of the third millennium the Quadrant has been completely overhauled by Les Williams and Arthur Jakeman both former Triumph forming part of the working team led by Doug Hele and considered today among the most accomplished restorers of the Trident!

I assumed it was an English bike all along. Searched frantically for it as a Triumph, BSA or Norton and others, but could never find it. One of the grainy photos you posted looked like it might be a four cylinder or a three cylinder, ala Trident with split center exhaust.

 

Anyway it is a 1983 Triumph Phoenix with a TWIN cylinder. Apparently with four exhaust ports. Variously a 900cc or 750cc capacity. A prototype water-cooled, 900cc bike called the Phoenix (the engine was also known as the 'Diana') is designed in early 1983 (a water-cooled, twin OHC vertical twin). I have a little info from book Triumph Bonneville Year by Year book author Paul Hazeldine. There is a pic very similar of the donk from the other side and a darker pic of the mock up at the show taken from a front view angle, hard to see really. The text reads something like ...

The proposed Phoenix first mentioned late 1982 is a water cooled DOHC twin with 4 valves per cylinder chamber. It featured at the Birmingham Show 1983 as a complete bike mock up. It was placed in a remote area making close inspection difficult. It had four exhaust pipes, only two silencers, the engine a stressed part of the frame with a monoshock rear suspension, cast alloy wheels and disc brakes. They were up with the play really, what could have been.

 

The show display was in March despite the fact they had ceased production in January, and in August the company as history tells, went bung, the phantom bike was never made.

 

There is also a better black and white pic in "T140 and Derivatives" by Roy Bacon of the Phoenix 900 which says the engine was coded "Diana", now Roy is a Trumpy, Beeza, and Norty guru writing many books on these, he should know.

There's also some footage of the above engine actually running, so it got that far in development, but the man in the picture at the top of the post, the owner of the only bike built, mentioned that it's a wood and clay mock-up, probably the reason it was displayed on the roof of Triumph's stand at the bike show in the film.
