I remember watching Ron Haslam racing a JPS Norton Rotary, the exhaust pipe was glowing a dull Red ( awesome ). It was rapid on the straight but the piston engine bikes caught up on the corners due to the Norton having to rely on brakes alone ( not a combination of brakes and engine ) to slow down, once out of the corners the Norton left them for dead... amazing engineering and amazing exhaust sound...Great upload VisioRacer, thank You.

5:57 Norton should have concentrated on developing the time machine that enabled them to get PCs and CAD software in the 1970s

One Norton rotary was said to have been fitted to an Austin Metro from 1981-1983, the car was demonstrated to Austin Rover who lost interest when they found it out-accelerated their MG Metro Turbo. However from Oliver Winterbottom's book A Life in Car Design, the above was likely connected with a project between Norton and Lotus known as Project Nora for a Norton rotary-engine coupe around the same period that amounted to nothing when it became apparent the rotary engine was not ready for automotive use.

There was a stunningly accurate replica built in Australia back in the early 1990s. It may still be floating around. And yes, it ran a modified Norton Rotary built as close to spec as possible. Norton were very reluctant to provide any assistance, so the builder had to work everything out himself. From what I read at the time, his lack of data relating to the intake manifold length led to superior results over the original engine once he had the length dialled in. Karma, eh?

The rotary engine just isn't as good as a piston engine in the vast majority of applications. They have a total loss lubrication system so they pollute badly and there's no way around it.

Maybe it is nice to know that Midwest developed the Norton 294cc wankel single rotor into a certified aircraft engine. The AE-50R. Most of the Norton technology was still used. My glider, a Alexander Schleicher ASH-26E, has one installed. Rated 50 hp at 7400 rpm. Beginning of the 90s, Midwest was taken over by Austro Engines, who developed this further into a fuel injected variant which is still in use as glider powerplant. Look up ASH-21 Mi, ASH-31 Mi and ASH-32 Mi. At Austro there were even developments of more powerful versions but they never made it into airplanes..

I have had 2 of them a p41/42 ex police bike I build ad a cafe racer and still got a F1. These engines are so amazing, but people don't believe in them. Brian Crighton got 200+ hp out the old 588 design and have continued. It died to death after FIA (officially) banned them yes, unofficially tho, a lot of money was payed to FIA people from everyone who didnt have wankel race engines (read everyone but Norton and Mazda). I could go on forever on these engines !!!! Sorry for the edits, I have the whole history of the Nortons and all the different people fighting to get from my brain to my keyboard 🤣

very interesting, I never knew this much testing went into a rotary motorcycle I used to have an 04 rx8 manual and it did lack torque so I always said with the rotary advantages of smoothness and light weight it would be better in the lightest vehicle possible such as a bike or the Miata and that the rx8 would've been better with a 4 banger and skinny tires like what they did with the FRS/BRZ.. wonder why they didn't consider forced induction with the early Norton when trying to increase power numbers, assuming the tech wasn't really there yet plus longevity was also already an issue.. anyways I'd love to experience a modern rotary sport bike, mayb they could incorporate some carbon fiber internals somehow

Obsolete technology

"water cooling was proposed but allegedly would not be well receibed by customers" Customers: yes we want out engines to overheat and burn, fuck cooling.

The displacement of 588cc isn't really true. In reality, engineers don't agree on how to calculate the displacement of a Wankel. While some would say the Norton was 588cc, many would say it was really 1764cc. It all depends on how many chambers in the rotor housing you measure. Certainly its fuel consumption was equivalent to a 1.8L engine.

Suzuki also had a rotary engine'd bike in the mid seventies. Suzuki R5

I have to say that the rotary engine technology has been suppressed for many years but but wouldn’t be today !

And now Rob Dahm has a need to own one of these eccentric beasties.

1:20. The engine shown there is NOT the Rolls-Royce wankel. It is the John Deere SCORE 580 2-rotor engine, which was designed in the mid-1980's. As a young mechanical engineer I participated in the development of that engine. The Rolls-Royce wankel was an engine with 2-stage compression, and true compression ignition. The Deere engine was low compression with spark-assisted ignition. Other than that minor point, marvelous video! There will always be a place in my heart for wankel engines, and the people who create them.

No, it is not a Rolls-Royce engine. I overlooked it in the post-production otherwise I would have put the info title.

IIRC, Trevor Nation was interviewed after winning one race on the RCW588, and said "It's such a quick bike that they could have put any competent rookie rider on it and it would STILL have come in first. The first place of any competition this bike enters is pretty much already in the bag. The REAL race is for who comes in 2nd, 3rd, and 4th". From what I remember in bike magazines back then, It was only really allowed in the 500/600CC class because in a few EU countries at the time, for racing purposes, the capacity of a Wankel was calculated as only ONE combustion chamber volume multiplied by the number of rotors (rather than the more usual 1.5 combustion chamber volumes). In most other countries it would have been getting trounced in 900CC+ race categories.

The only thing Norton lost more than races... was customers. The Wankel engine was ultimately a failure that destroyed the company.

Suzuki did dabble into the rotary idea with the RE5 but so be it very briefly, not compared to Norton which sort of affected its reputation.

The problems with Wankel engines aren't only unreliability and lack of power at low revs. The Wankel is a fundamentally flawed design.

Better than the Suzuki RE5? Suzuki still had engines for the RE5 in stock In some of its warehouses in the US as of six years ago I remember a controversy about the Norton rotary when it was competing in road racing. The officials did not know whether declare it a 500 mL or a 1500 mL engine because of the three sided rotor. I’m not sure about the initial displacement but it was an issue

Check out the Liquid Piston X. It's a revamped rotary that overcomes all the downfalls.
