Crighton CR700W : What makes this bike so special? 

The world needs more of these bikes ❤

Seeing and hearing riders such as Steve Spray, Robert Dunlop, Ron Haslam cane the Norton Rotarys around the TT course was imprinted on my mind for ever, 22 years of looking later I get my own Rotary! OK its no where near the highly refined machines from the genius Mr Crighton but for a fact it gave birth to the 588 Nortons. I got myself a Hercules W2000, paint and chrome was shot but it was all there and 1,400 genuine miles with a pristine rotor housing it was brought back to A1 condition without the need for rare engine parts. What does it go like? A Bantam on steroids! Pop bang wirrr bloody hilarious to ride, rubbish hunting on the overrun but I love it. DKW who sold under the Hercules name in USA committed to selling 2000 in 2 years, fell short of the target so sold the rights and production equipment to Norton. My single rotor 294 is half a Norton. Mr Crighton could you tweak my Herc please 27HP not enough!

I love this bike! Amazing craftmanship.

The specs are insane, just as the sound is! Love it! ❤

Such a wonderful sounding bike... Love them.

A rotary won the bsb championship in 1994 , they later banned it because it was faster than than the rest of the grid!

I've always loved rotary engines, motorcycle rotary, automotive rotary, Suzuki RE-5 was one I'm familiar with we sold them at the Suzuki Shop I worked at in the 76,77,78,79. I turbocharged many Mazda RX-7'S, those engines rev higher and thrive on turbo's & nitrous oxide,light, compact,lots of power too. That bike of yours is really something

crighton solved the inherant rotary heating problem by feeding coolant through the e-shaft, keeping the center of the engine cool.

If I remember correctly, one of the issues with rotary engines - I'm thinking of the Mazdas, was the seals at the ends of the rotors would wear and fail which was a weakness that I don't has ever been resolved. I had an RX-2 and it was pretty powerful for a small lump, and when it got to a certain RPM it was like a VTEC engine, suddenly there'd be just gobs of power and it would take off like a scalded cat.

Great video and commentary. Finally someone who actually showed what we wanted to see,,, the guts of the engine😊. 👍

Fantastic insights! Brilliant video guys. Looking forward so seeing more. Subscribed!

Now all we need is a singel rotary dirt bike. Now that would be something AMAZING.

Wish thay would make a modern 750 2 stroke bike or bigger 😂 i love anything 2 stroke or rotery

Wish them the best❤❤

Fantastic video. I can't believe I'm one of the first 500 subscribers to this channel.

I had a Norton interpol 2, seized the engine and spent £1200 having the engine rebuilt in Shenstone by Richard Negus. Worth every penny.

Superb design ideas

Interesting bike, and good video!

Smooth running as they come too.

brilliant engine!

same size motor as a rd350 - work of art! I want one

I need this to get to work, early.

Guy Martins test ride on one of these was awesome.

That's shear genius! 💯

I think it’s mega, I would love to ride one 👍

Okay...I'm sold! When will the road street legal version be available!!!!

I had trouble following Mr Crighton's fast speech, the auto subtitle helped a lot.

Fucking awesome. I want one.

The greatest bike ever ! I wish they sold this engine by its self. Stock standard PP !!!!

that bike is crazy.

I'd love to see sponsership for one of the top 10 IOM TT 2023 competitors put this beautiful bike through it's paces at TT 2024 🙏😎🏍️❤️

This machine is a masterpiece. A Wankel freak myself. Same class as that 575 2T built in Switzerland. Just can't get on the guys name. Builds schassis for moto 2.

I’ve had a Mazda rotary rx8 and it lacked hugely in torque, was a gas guzzler and even with top quality oil regular wore out fast. Think it’s great that people keep trying but the blue smoke when he revved it I wonder if it would ever comply to latest emissions.

The twin rotor has the firing of a Six cylinder two stroke in a smaller package for the power output, incredible for Torque and power … I’d love one …. Gotta be smoother than my 1981 GSX1100 …

Spondon Rotory, Yess please

More beautiful than anything from the big boys

Please put one of these engines in a super kart 🤠 Would be nuts having 20-30 karts racing on a full size circuit with 200hp at the wheels 🤙

I so wish I could afford that bike..

Is there a aftermarket transmission of that type available for bikes?

Cant wait for a triple rotor turbo 🤘

Steve spray and Trevor nation brilliant watching them on the JPS nortons

Wouldnt that be a nice ad: CR700W, ‘its f-ing fast!’ 😂😂😂

did crigthon sale the engine individually or full bike?

What makes it special is Guy Martin rode it and loves it!

I think the end sce e w the bike stumbling and amoking oretty well sums up rotarys.

Would love to learn more about this ..any work going ???

If some body wants a track bike that is lightweight, plenty of horsepower and only for the track, then perhaps the Suter MMX 500 could be a better option. That will at least finish a few laps at any track before needing to stop for fuel. Having a rotary bike will mean you get 15 mins of track action before needing to come in to refuel. Great conceptually, but will be terrible to live with. I wished the host would ask questions that will add value rather than prompting the Crighton representative to say things on the pamphlet

What race class would you put a 2.1L bike in...??

Will go on sale?

the exhaust sucking air through the engine to cool it is something you will eventually see used on other bikes, maybe not rotary but air-cooled 4T engines need all the help they can get, air-cooled 4T engines are simple and easily maintained but tend to run hot so extra cooling with no moving parts is an obvious progression, it could pull hot air from the barrels & head with a shroud or casing and reworking of the fins, I'm thinking Suzuki ram-air system used on the 1970s 2T GT's hooked up to an exhaust system like this bike has ! anyone up for the challenge, get in the shed,

Very nicely made! But why does it smoke like a 2-stroke?

What is the wear on the rotor lobes like .

interesting i think the big brands are watching because in 2027 in Motogp the engines will be with less CC

I notice the Parajet posters on the wall. When is this man going to design a rotary Powered Paraglider engine?

I can't find it back but I saw a video about rotery whereby they turned the working" inside" out wich solved most problems a rotery is know for like the seals ect. When I saw it I was like amazed how simple the solution was just turn the workings around. Mazda chefs must have had a burn the day they see that video.

What is the torque of the engine and at what rpm is the peak power and torque? Can you show a power graph

When will i be able to buy one

I believe they were intially sold for around 95000 GBP. And that is not a ridiculous price for a motorcycle? From a manufacturer no one had ever heard from? Who is kidding who? This world has gone completely mad!

Cool toy but what is the point? Will we ever get to ride it? Will it ever be available?

I want 1 ,I reckon it's got potential too kik arse.

This overall design was brilliant when introduced by Mazda many years ago, and it’s still brilliant for several important reasons. But Mazda was never able to develop rotor seals, capable of holding up to the heat, friction and pressure loads they are subject to. Has this engineer worked that out? If so, I want one for my airplane.

Cant wait for the 600 bhp turbo version.

I like it, but no shock linkage...?

I would most likely buy one if it cost like a BMW S1krr or a Ducati V4 around 20k Euros! But not 120k Euros.....

Totaries have slways shown promise.They had a problem with the rotor rings which wore away qiickly and the pettol consumption. Both curable.

The world thinks were advanced and that consumers can buy the best cutting edge tech/machinery/vehicles. But we have what we have because of regulations, not because its the best. Rotarys and 2 strokes are 2 engine configurations that are far superior for performance applications but have been written off by major manufacturers.

Stunning bike. Does it have electronics? How did it keep the front down at such a rediculous power to weight ratio?

@4:12: More vacuum, more power, more cooling, and then the sound of more methane.

so why is it not in gp or sbk, i mean why havent manufacturers adopted it

I want one of those motors for my shifter kart….

💯 % 🇬🇧 👌👍

Torque curve on the wankel is wild.

I guess most people don't care, but the cloud of smoke would annoy me. Does it go away? A shot of it running without the cloud would have been awesome.

will this bike start a revolution?

Why does it smoke so much on start up?

220 HP ?!!!!! I’ll take two please !

When I win the lottery I'm buying 9 of these...

MotoGP only for Italian. They won't let this beast enter their playground. CHICKEN

Many "keyboard" experts on here...........LOL What an amazing machine & one of passion..... Full credit to Brian for all the effort in making this a reality

Here I've been throwing about the idea of making a single rotor version of this with half a Renesis or 13B,..

Most of Respect. Every time i think, the Rotary or Wankel engines are History, there are some new ones. Also Mazda surprises some weeks ago with a new fascinating Wankel.

Why does the rotor only fire once per revolution? Wouldn't it be more efficient and more powerful to fire on every "stroke"?

Rotary way to go!

Ok... you've got my attention. What's the cost???

Imagine a single rotor dirtbike

Interesting concept and execution… poor application considering the excessive oil consumption and the near complete lack of low/mid range torque that plague all Rotary engines ….that is unless you rev the snot out of it which you never see in any videos concerning this motorcycle…hmmmmm???

Only 96 subscribers??? ..... having watched THIS, I'm really not surprised! You neglected to ask him why the wheels are round?

Why is that shock not tucked low and inside with a rising rate linkage on it? Bloody daft to use that configuration.

This is very cool..and all that..but the biggest oversight is that rear suspension setup..that bike is absolutely useless without more modern linear suspension or some kind of linkage to make the rear predictable..that is like 75% of racing is making the power usable.

Take my money!

Ooo,modern day Britten.

What most people fail to realize... 700cc rotary = 1400cc piston equivalent... not because rotaries are better.... just that they displace their volume every revolution, instead of every other revolution.

Why so much smoke though?

Dear Santa... I have been very good this year...

The question.. How many gallons per mile uhh.. Sorry miles per gallon does it make?😊

She's a good air pump.

Get your 1973 Suzuki rotary out the garage. Nothing new but updated.

Fantastic design, but I don't believe reliability and emissions wise they'll be able to make it work?

Make a 3 rotor version...

Why did it generate so much white smoke? Must be suffering from oil burn 🔥, like all rotary motors.
