You seem to have overlooked the Royal Enfield Flying Flea .

Ace photographs 👍

Imagine if this did get made, the 70's would have been vastly different and a lot of fun.

Cb 500 4 because I'm a bollix.

Great video .I owned several of the ones you covered. 85 vmax Valkyrie Rocket 3 .I finally settled with the Vrod.❤

I had a few of them, including the Norton 850 Commando....

I own a 1970 hl m 1 monster modified, Dyno tested at mmi in Phoenix, 1985. At 130 HP. Red lined at 13 ,000 RPM. We called it the kamkazi dirt bike!!!

Esa Harley gris mi favorita

Never knew about this one. 1 loved my Z1000. Cheers for posting

Great video! I have a 2021 Gear Up as a daily driver, it turns heads everywhere. And now my 2 year old daughter climbs up into the sidecar and wants to ride with me.

If Kawa brought this out and Yamaha also produced their concept 750 4 cylinder 2 stroke, it would have been the showdown of the century.

LOL! I remember well the 2 and 3 cyl 2 strokes in the late 60s and the 70s! They were awesome to ride but also dangerous if you did not know what you were doing.. Especially the 750. the smaller ones were a bit more manageable. BUT if they had come with a 4 cyl? That would have been just sick! I guess I would have lacked a few more friends then. Good it never came into production....but what a rush that must have been!!! 😆😆

There's pics of a Yamaha in line 4 cyl 2 stroke from the same period on the net as well.

Oh yeah good stuff! Why worry about negative bull, and your at least as handsome as me! Keep up the great work! 😎

Although I was around back then this is the first time I've ever heard of this bike. Really interesting design. Thanks for the education. Great video.

The KR750 motor would have been so much better

The voice of reason. An Aussie voice too. Any bike can be dangerous if not ridden correctly. Smoothness with every operation of the motorcycle makes the ride more enjoyable & it's good for the bike too. Just chill on the road.

I think Kwaka at least addressed Ariel`s old issue of not being able to keep the rear two cylinders cool , which did eventually killed the the Squaffer .As you correctly pointed out, Kawasaki gave their square four liquid cooling . That in itself would have been among the earlier manufacturers to use this concept of keeping your motor happy .

I would have loved this bike to have got into production, but I fear it's run may have been very short due to the oil crisis of '74. I wonder if Alan Millyard could be persuaded to build one though........

Great review m8 100% true my brother had a rd 400 dx in white and red also some friends that time had xs and kh 250s and kh 400s but one chap in 1978 had the honda 400 super sport in red that was a good bike as well years later my brother had before the rd 400 his first big bike was a kawasaki z200

It was the Middle Eastern Oil Crisis, in 1973, that started killing off the development of gas guzzling, large capacity, high performance 2 stroke bikes. My old Suzuki GT550A could only manage 9 miles per imperial (true) gallon in town riding and 18 miles per imperial gallon cruising at 45 - 50 MPH on the open road. By comparison, my considerably lighter (in weight) 1979 CZ 350-472 Deluxe could manage 67 miles per imperial gallon cruising at 65 - 70 MPH plus could take corners like it was on rails. It was also far more reliable than my GT550A.

Apparently it had way more poke than a z1, worse handling than an h2 and cracking heads/overheating problems.

I saw a kawasaki square four in Okinawa Japan in 1986 but it was a 400cc engine, even though I race motocross under the shops sponsorship he would not let me ride that bike, was faster than anything on the track but was a street bike, The time I was there it never sold and I never saw another one like it

Over to you, Mr Millyard!

I had the S2 350 triple. I'm looking for another to replace the one I sold many years ago.

The main issue I had with my 1972 H2 was oiling plugs riding around town 🤫

I tried a lot of these bikes and then bought the 1980 GSX400S. It consumes 20% less than these 4-strokes, and 50% less than the 2-strokes for performance at least equal to the RD400. For documentation on the 400cc (in French but the figures remain accessible) you can consult : 'le grenier de Jean POL', 'moto revue'. Numbers: 2281, 2299, 2488, 2497, 2554, 2576. Bonne lecture !

The CB77 305cm³ 28.5 SAE HP and 105MPH is missing! (compare with the so-called 43HP DIN of the Honda CB400N...and other)

Can't take the accent. It's like fingernails on a chalkboard. Goodday mate.

This engine was poorly born. Little room for transfer conduits, different inlet lengths. Only one carburetor for 2 cylinders. Lack of space for exhaust pipes. Long engine block preventing the swinging arm from being extended. Red zone at 7500 rpm so a peaceful tractor. Aerodynamically it is not any less wide, think of the driver's knees!

Yes, I'm old enough to remember that, along with Yamaha's equivalent, the GL750. In fact a friend had money waiting for the Yamaha if it ever made it into a showroom anywhere near London. The Kawasaki might have been ultra powerful (by the stds of the day) but to my teenage eye that engine looked awful, like something out of the 1930's. It lacked showroom sex appeal - an essential element that the H1 and H2 had in spades, and none of the people I knew were that interested in it. It was a bike for the age group I am now. Had they engineered it like the RG500 Suzuki that might have been different but not as it was. The Yamaha would have sold, the Kawasaki would have flopped. My opinion of course but that's how I remember it being discussed when these pictures of these bikes made it into the press.

Tell Allan Millyard ive found his next project.Would have been a weapon no doubt about that,i have seen pics of it before in books on the history of of Kawasaki.Your pics look great,hadnt seen those ones youve got.Thanks for sharing,love the Aussie humour.

I smell a rat.

Is it me or did 70’s motorcycles look more like motorcycles than the generations after?

It’s not pictured here but I owned a 1974 Honda CB 360 my father gave me. I rode that thing daily and sold it to buy a Kawasaki GPZ 550 in the 80’s. When I was 9 I was gifted a 1974 Honda Z50. That was my first motorcycle. I graduated to my first “big boy” bike with a used Yamaha 80.

It WOULDN'T have been a widowmaker, cuz it would have killed all the widows as well.

Hmmmm... 4 cylinder 2-stroke liquid-cooled 750. Can you say TZ ?

Great Video! I Love Learning About Motorcycle History! Live Narration & No Crappy Music Just Made It That Much Better. Thank You. (Like #58)

They should have made it 😢

Fabulous design - I have never seen so many pictures of the bike - thanks for posting . . .

Thirstiest too. But who cares about that.

Yamaha TZ750.

Oh to be able to change the spark plugs without removing the tank. 👍

if it had been me... strap three kr250s together... yeah. square six :) *tasked with changing seals, throws bike away*

Who on earth is this tone deaf band slaughtering the legendary Ballroom Blitz???

It would have been nice to see that in their line-up.

What might have been... Yes, it would have likely been the most powerful bike of the day. Methinks that they scrapped it so as to not steal thunder from the Z1, which was their prestige image-maker long in development by 1972.

Amazing!

👍🏻👍🏻👍🏻👍🏻👍🏻👍🏻great video again Digger. I took your advice and put new Bias tyres on my ROYAL ENFIELD INTERCEPTOR. It handles BRILLIANT..... THANKYOU FOR YOUR ADVICE!!!
