Guy Martin onboard a ROTARY bike 

Assen.

@@flintstoneengineering it would be epic to see!

TT 😂

It has to be the TT but that will never happen but to see how good it really is it has to be in a proper race against other top machinery. Otherwise it is just words. It is easy for anyone to say that the bike they built or pay someone to say that it is the best thing they ever rode, but there is only one way to proof it. On track.

Against other bikes but would love to see it get flat out, sounded like he never really got past half throttle, wanna here it top rpms

From 700cc 👌🏻

@@JohnSmith-ws1dp 700cc every 360 degrees. So it's 1.4l compared to a piston four stroke ( every 720 degrees).

@@opiumtrail7032 ”ok”

I'd love to have this style of bike 🏍 with a turbo 2stroke twin cylinder with 280hp, and the same weight!..from Wyoming USA 🇺🇸 👋🤠

Absolutely! He's not backwards about coming forwards

Definitely

A single rotor wankell engine has a torque pulse distribution stable and equivalent to most inline 6 engines, internal unbalanced inertia and transience is reduced. With a single cylinder it could weight as much as a v4 and it would still beat most v6s on a motorcycle. Now consider this whole bike weights as much as 125cc single cylinder "delivery" bike. The only way to make it faster is resumed to turning it into a superkart. This thing is above v10 and v12 era F1's.

He Never tasted a MotoGP bike tho

​@@LNVACVAC hahaha, better than the last F1 BMW 3 litre v10? that's just utter nonsense

It's all because every big race event has banned rotaries🤬. RX-7 GT300/787 B was such an amazing race car. All because of those fucking f1 rules that went to the every racing event. Fuck f1

That must be why they don't tend to last so long. Anger eats you up inside 🙂

Yeah it only took about a lap in a half. Looked quite scary down low with those pulses bucking the whole bike

He's a smart cookie

TY

Rotary engines have no engine braking and the power is instant so Guy worked that out instantly .

All bikes are like that ya dingus

It was a brilliant sound bite 😂

❤

You can see that he is full of adrenaline while speaking about bike, even his neck vein is poppin out that bike must be hella fast if your body reacts like this :D

"technical term "

Bruh all sportbikes sound almost EXACTLY like this....I'm guessing you're not a rider...

@@LegalLowGround sureee, might be you being deaf from all the fucking riding you do without hearing protection.

sounds like a 2 stroke cricket

Il suono è unico, un 4t 6c con qualche nota 2t. Motore perfetto per una moto da corsa, leggero, compatto e potente.

Nothing sounds like this. Get your ears checked.

Just found your wonderful comment shaun..many thanks for that great information and there's no doubt your grandad is a genius...no doubt at all..I wish this technology could filter down to the masses for everyone to be able to experience such engineering excellence..I remember the previous bike and that was a weapon. .this one is a guided missile..it's everything a race bike should be. Light, flickable, powerfull engine with great handling..great job...the bike should sit in the bracket as brittons 1000cc v twin beast..

Sport bikes are the perfect application for rotary engines, as rotaries have issue with low / constant RPM both with carbon buildup and case cooling. It looks like your granddad has been chipping away at some of the challenges that rotaries have presented over the years. One of the biggest is the inability to tune intake/exhaust overlap, in a rotary, both are fixed ports on the rotor housing, so intake/exhaust timing is handled by the length of the port and the proximity of the intake to exhaust ports from one another. Getting a rotary like your granddads to scream with a huge powerband up above 5K RPM is pretty easy with rotary, but always comes at the cost of low-RPM power and drivability, as you'll notice the motor will tend to sputter and break up under 3000 RPM. Bridge porting will greatly increase power in the high-RPM, but also at the cost of a lumpy idle and poor low-RPM throttle response, like having a huge camshaft in a piston engine, and peripheral porting / semi-peripheral porting will turn a rotary into an F1 engine but the low-end performance is abysmal. I'm betting your granddad's rotary is using peripheral or semi-peripheral setup. So, unlike a piston driven car with cams that can have variable valve timing to provide a wide range of performance or economy depending on demand, with the exception of variable length peripheral intake ports, rotary engine intake/exhaust timing, size (lift), duration is static, so an engine built for the maximum high-RPM horsepower will always suck at lower RPM's, gobble fuel and clog itself up, while a rotary built for lower-RPM torque and better economy will be pretty anemic up top. There was a team that was working on electronically actuated port-valve along with peripheral ports on a rotary engine, sort of like VVT or VTEC for rotary, where a special valve is inside the rotor housings that is actuated to change it's size and location, so you have this gigantic peripheral port, but the valve inside can move forwards or backwards to adjust timing / overlap, up and down as well as back and forth to adjust port size and geometry. If they perfect that technology, that would solve so many of the negatives of rotaries. Anyway, you're grandfather is a rad dude!

G’day mate! Australia

Cracking granddad you have mate! Wouldn’t mind a bring your kid to work day in this family 😂

Thanks for pointing it out! I love the rotary engine but it has it's drawbacks ofcourse. This is a major improvement!

Guy Martin on Masterchef... Interesting...

I don't feel that something special, if I'm not into the thing, it seems silly to me 😢

@@solidfuel0 The Vid or the idea of Guy Martin on Masterchef? EDIT: Lol - I can see if you're not into rotary engines, this Vid doesn't seem all that special...

Holy Smoke - It's got a higher power to weight ratio than a Hennessey Venom GT2

I'd daily it.

@@luko560 That's the best part.

Best first bike fr

No Awesome!!

i believe it has two rotary chambers, side by side. so 1400 ? in a 250 gp frame ! gulp 🏴‍☠️ & yes wankel was brilliant.

i own RX7's and yes the deceleration is an issue. the engine has a lot of inertia because its spinning rather than going up and down. so its a challenge. you can alter the ignition mapping and fueling to get it to slow down. its kinda like when F1 had the blown floors and they were using ignition cut to keep it going . its the same as that. 2nd issue is the low end. big ported rotaries are very lumpy down low and you can see how it runs quite rough down low. this is not fixable its how they run. so those are the 2 issues rotaries have. but as you can see the top end and overall power is nuts. plus there is a lot less power losses through drivetrain again spinning not going up or down like pistons. so there are some advantages

@@seinfeld11123 I mean the second issue isn’t really an issue on the track, right? Only the start is a bit rough but after that you won’t hit the lows anymore

​@@seinfeld11123 and reliability, a big issue for Wankels

Imagine putting a 13b or 20b ?

Sounds like an old 2 stroke! Awesome!!

Kewel😊

I don't think Guy was impressed! He just was nice to the engineers team!

​@@SummerTrianglehe was

Humility

​@@peterherrington3300 No need for petering around

Absolutely agree. Ironically, against all he is saying in the video, if I was designing & building a bike, I'd listen to every single one he says. He sucks in engineering knowledge like a savant. What a bike! What a good lad. Great video.

Good work :)

The Algorithm cannot be defeated and it absolutely will not stop! :)

​@@slammerf16 lol

Oh it is incredibly light! I've pushed it around and it feels like nothing

love your profile pic mate haha :)

@@ILikeMotorbikes Interesting. Does that translate into amazing handling?

@@protopigeon ; - )

@@Unfunny_Username_389 I'll let you know if I ever get to ride one 🤣

Me too mate, (64)😅

The day Hizzy won the 92 senior TT on the Abus sponsored rotary is unforgettable. A great day at the races indeed.

There is a po-po-po in the low rpm and the bike looks like shaking.

@@howardosborne8647 I had the privilege (and I use that word sparingly) of being there to see it. Foggy plays it down nowadays but Hizzy and the Norton won it fair and square.

​@@aaxa101 It's Caldwell park, not some super smooth purpose built Gulf state vanity project F1 circuit!

Glad you liked it and cheers for the well wishes

Thanks for the kind words. Sadly I was limited by the placement options for gopros as directed by the team so apologies for that. Glad you liked it!

Electrifying is such an obvious thing to do in our modern world, but it's also very underwhelming to see or read about. Some company claims to be developing an electric bus? What they really mean is they saved up their pocket money and put the most mediocre battery, motor, and controller into a bus all while claiming they're pioneers and innovators. The three major components of any electric vehicle is a battery, motor, and controller, and the technology for those hasn't changed much in the past decade or so. Everyone's relying on third parties for components, especially batteries. There's nothing particularly clever about any of it. Electric vehicles make a lot of sense for a lot of reasons, but between the engineers who aren't really engineers and the relative simplicity of an electric drivetrain, there just isn't much to get excited about. Tesla come close to being interesting only because they've managed to exploit the shit out their batteries with their BMS, which some claim is 10+ years ahead of the competition, but in reality is just down to how they're programmed.

@@Metal-Possum The car drives into the station, the driver goes to take a leak. When he comescback, the standard dimension battery (so "everybody" can work on making better bateries) has automaticly been swapped from underneath, and he is off in under two minutes. The difference between the batteries is paid for electronicly - THEN electric cars are redy for ordinary use.

@@CONEHEADDK If that's the case, batteries should be rented not owned. Tesla already trialed this idea and very few of their customers actually wanted it. You'll also be hard pressed to find a successful company like Tesla agreeing to conform to someone else's less good standards, or the complex relationship between Tesla allowing a competitor to use Tesla's superior battery modules, and the competitor actually wanting to use Tesla's modules at some expense. However, that's not the point I was getting at. The point is that when I see people "developing" battery powered buses or trains or trams or boats. I don't see any actual innovation. It's usually just a bunch of enthusiasts wondering what they can stick a third party electric motor into next, with results that could just as easily be calculated... *yawn*. I want to see some actual breakthroughs, something revolutionary that actually convinces the world electricity isn't just some experimental vehicle made from some Radioshack electronics kit for 10 year old kids. Powering a bus with a potato doesn't tell us anything we don't already know, we need to be exceeding expectations rather than merely pander to them, and that's going to take a company that's actually willing to invest in technological developments, rather than just buying off the shelf components and half-assing something that could have been exactly the same 10 years ago.

@@Metal-Possum I understood your message. I just see through Joe Average's eyes (the danish Joe - I live in Denmark, and "all" anybody seems to care about is recharging fast, so the cars are as functional as real cars. So if you can't recharge fast enough, you swith the batteri like in your toy cars. 90-99% of users don't have a clue - they ust want a PC car that does the job (and don't really give a fook how many black8 yos have been poisoned digging for materials for it) - in the colour the wife has chosen..

Well said Sir 🙏🏻

Absolutely

That will never end 🫶

787B ❤ (sorry it's a car)

It was always great in outboards as well just as powerful as a 2 stroke but lasts 3 times as long & only used half as much oil as a 2 stroke… great compromise imo…

Not suited to race bikes though, what category can it be raced in given its engine capacity.

@@georgebarnes8163 they’re absolutely suited to race bikes. small displacement, small physical size, high revving, high horsepower, and relatively high maintenance (insert apex seal joke here). You’re correct that there’s not really a class they suit at the moment, but that’s why classes like super bike and Supersport have different displacements per a given engine layout. Classically for example, 750cc inline fours would race against 1000cc v twins. And more recently they allowed 750cc v twins and 600cc in-line fours race with 675cc in-line 3s. It’s just a matter of horsepower to displacement math to determine what class a rotary COULD race in.

@@f0XxXxXxX yes I always loved the Mazda 787B, beautiful, fast, and sounds amazing. I just never dug the idea of a rotary engine for like a daily driver. Personal preference I know, because I would love an FD but won’t ever be able to afford one lol

It's mega isn't it?

exactly. it was nice to watch how he got used to it and lap after lap you could see that he allowed himself to add gas, give him this motorcycle for a month and he would only show what's in it. Martin is the devil 😁💪

People who listen to their voice

Having been to gatherings at Betws-y-coed, I'd say you are a youngster!

go ask them how much for the engine.. steal the engine plans and sell them to me..i will sell to suzuki and ask them to mass produce these in north korea so the whole world can enjoy this at affordable peasant prices🐱👍🏿

​@@fidelcatsro6948mf 😂

I had an RE5 and a GT 550 Suzuki and the rotary was quicker and smoother almost like a three cylinder fourstroke which of course technically it was ... But this ...this is something else !

598 cc I believe, with twin rotors.

I’m know, I just love the sound of Guy talking. The bike made some good music too.

exactly: emissions and gas guzzling. the elephants in the room FOOLS
