Cool. The slipper clutch on my Mazda works a little different. It starts slipping any time I give it more than 90% beans or if I'm going up a particularly steep hill in 4/5th gear.
Those ones are good for fuel economy
This type of slipper clutch has the added benefit of making it very difficult to stall. Good feature.
Haha, I had a 93 ford 1 ton diesel with a slipper clutch that only acted from a dead stop or under heavy loads. Think of all the torque I was able to avoid!!
Slow the oil leaks on to it for less slip, increase for more?
It makes intense burnout effects without stupid tires getting all used up c:

Understeer is when you go off of the cliff.
Oversteer is when you go off of the cliff at the same place, backwards.

😄. A very Matt-esque explanation. 👌
Understeer is when you can see the tree you're hitting.
If you can only hear it, that's Oversteer
(Walter Röhrl, WRC Rally Legend)
Depends if the cliff is on the inside or outside of the corner. 😀
Oversteer is when my passenger spoils his pants, understeer is when I spoil my pants 😊
Nice lol
Looking forward to seeing how you integrate this into the Jag...
its most likely for the honda
edit: dont whooosh me
@@DarkIzo ;)
@@DarkIzo LoL for the edit
@@DarkIzo doesn't the engine in the honda have a slipper?
@@billbergen9169 This one is adjustable, like he said in the video...
"Take a drink every time Matt says "Slipper Clutch.""
"Hello, everyone. My name's Paul and I'm an alcoholic."
Mmmm sipper clutch
slipper sipper
Id rather drink everytime he says clutch
@@EmeliaBelle I'd hail that algorithm.
I am glad to know I am not the only one who takes apart brand new items, just to see how they work. Sometimes I even get them back together again.
Stop making consistently good, interesting and amusing videos. Your wearing out the like button!
They have only themselves to blame if it wasn't sturdy enough.
When I bought a clapped out honda one late night in an alley it also had a slipper clutch
A dual direction slipper?
....... another episode where Matt explains how technical doo-dads work with just the right amount of humor throughout 👍👍😎👍👍
As an absolute mechanical sky-high idiot i can say: that was easy to digest.
Also reduces the likelihood you will over-rev the engine on a downshift. I put a Yoyodyne on my Speed Triple. It's been awesome. That high compression engine would really give you an unsettling jolt if you flubbed a downshift cranking it into a turn.
Many years ago *Saab* had a manual transmission that included a *Sprague Clutch* . This device is like a slipper clutch w/o the plates. It is 100% engaged in one direction and 100% disengaged in the other. The engine would power the car forward but immediately drop to idle when the throttle was lifted. In rolling hills it gave an odd sensation of almost flying as you crested the hill and suddenly without the engine noise you were just floating down the other side. Some European EVs give the same sensation when set to make regen only with the brake pedal.
@@bibblybobbly9951 Probably one of the old 2-stroke models. Crankcase scavenged 2-strokes cannot easily tolerate being used for engine braking because they get lubrication from the fuel, being spun at high speed with the throttle closed basically starves the engine of oil with predictable consequences. So 2-stroke cars often used an overrun clutch to allow the engine to stay at idle speed on downhills.
An aside, sprag clutches are a near universal component of conventional automatic transmissions. They're used mostly so that the car isn't 'jerky' at low speeds- if you've driven a manual with a low first gear ratio you're probably familiar with the abrupt deceleration you get when you suddenly lift off the throttle in first. In a manual this can be avoided by using the clutch, in an auto there is of course no clutch pedal so some other solution is required.
@@nerd1000ify Yes, it was a two-stroke but I do not recall the model. This was in about 1980 and the car was not new. not my car.
The trabant 601 also has a device similar to this on 4th gear. Its also two stroke so it makes sense, they do not have an oil tank, its mixed with the fuel
lol just start dumping your clutch and you will get a slipping clutch for free
Unless you're in a car, not in a hurry... Wet, multi-plate clutches are extremely long wearing, even under sustained abuse.
The graphic of the bike leaving the track and bursting into flames made me laugh.
All Hail and all that jazz! What university got your tuition, Matt? Most engineers I know couldn't have done that four minute explanation with graphs, details and video support in less than 45 minutes. Awesome, SFM! FR
No outro about pleasing the algorithm? Where even am I?
A bit late to the party, this is such a great channel :D I think you can find those clutches on most bikes now. My cheap royal enfield 650 shockingly has one. It probably is the cheapest 650cc bike you can buy.
YES! I learned something!
Even though I was not told to, All Hail the Algorithm!
I feel like I would have a bad day if I watched a video and did not hail the algorithm.
This was actually super educational, I never understood how manuals can brake without braking till now. My friends tried to explain it, but now I get it.
Slippers and clutches... what is this, a fashion video? Next we'll hear about tanks and leather.
You've probably thought about it but it would be cool to see an electric motorcycle build on here. Or even a video about why you wouldn't want an electric motorcycle (current technology, use case, etc).
I love the mix of bike and car information on this channel. Very interesting info. I have slid the tail on my bike after a downshift even with slipper clutch. Guess I should be glad it had one and I didn't have a worse scenario.
Samesies on the slide
That is a quality company.
I never released 'buttload' was a technically term. Thanks SFM - you learn something everyday. All hail the algorithm.
Short, sweet and concise. Are you well?
Is this the Thomas Pynchon Yoyodyne or the Buckaroo Bonzai Yoyodyne? Or are they one and the same?
slipper and assist clutches are amazing, it should be standard on all motorcycles. prevents loss of traction during hard engine braking, and allows for lighter clutches
Learn something new every time I watch! All Hail the Algorithm!!
First time I've ever understood a clutch system better than "magic." Kudos.
I should not have watched this before work. Was drunk by the 2 minute mark of this video as per @SuperfastMatt's instructions to take a shot every time he says "Slipper Clutch"...
I enjoy the highly accurate and scientific scales on your graphs.
I was clutching my slippers the whole time while watching this video.
So what you're saying is, is that a slipper clutch works like a break diode in an AC-DC converter? :D
Or vocal compression on a drum track.
Lots of RC cars have slipper clutches too. Since the gears, driveshafts, and axles are typically plastic the slipper clutch helps reduce parts breakages when you hammer on the throttle from a stop since the electric motor is capable of producing a lot of torque.
I was just thinking last time I fiddled with a slipper clutch was on a R/C car back in the ‘90’s! And that was after I thought it wasn’t needed on vegetarian Jag…
I have a slipper clutch in my alternator pulley.
Great explanation. It also makes downshifting easier and more pleasant in normal riding on the street.
Oy.. wow ! Thank you Matt !!
[Preface: '04 Ducati 900ss/sp bike owner] .. always wanted to emulate/maintain period-correct FEEL of the bike.. visceral and exciting ! the End Goal' (something already there in stock form" .. quite a joy to experience..) the DANGER and EXCITEMENT is engineered into the fabric of the bike.
.. This video you've shared.. makes me want to install a slipper clutch unit .. and I'll enjoy it more than I thought it would.. enhancing the experience and feel of the ride..
Progress can be frustrating to come to terms with..
Was literally looking at slipper clutches for my CBR 600rr LAST NIGHT 😂
I never realized how simple the mechanism was.
Thank you for the explanation of slipper clutches. I thought I knew about them and how they work but alas turns out I only knew half of how they work.
Thank you for the insight and learning of slipper clutches. Now I need to go find my own slippers....
aw hell Al's got no rythm
Thank you! This was a question I've had for a while. Being generally stupid, I understand that clutch + slip = bad smell and dollars.
Interesting fact. The bike I'd consider the LEAST likely to have a slipper clutch has one. Suzuki VStrom 1000. They're the motorsport equivalent of flannel pajamas.
Yeah, over-steering off of cliffs isn't what its cracked up to be. Ask me how I know. T-6 paraplegic from just such a scenario. Hit some kind of debris(?) in a corner on a mountain road and tumbled over the edge about 100ft. Don't think this device would have helped me, but nifty tech.
I was like...WhY aRE wE TaLKInG AboUT A MotORCyCLE CluTCH?!?! then I remembered the whole S600 build. Duh.
Excellent, well really good, mmm just Ok, er average, so maybe under par? Absolute rubbish...how does this fix the Jag? Seriously...the Jag you should have started 5 years ago to be close (any time in the next two years) to be being finished (more or less)
(laughs in 2 cycle)
Why do we want any compression braking? Can't you just disconnect the motor from the wheels entirely (with the clutch) when approaching a corner, and just brake with your... brakes? Then put the motor in whatever gear is best for the RPM of the exit?
I looked at all the different slipper clutches for motorcycles. One's from $600 to 1,200. I guess it would be okay on the track. But all of them seem to break at one point and have problems
Now I no longer have to fake knowing how that works. Thank you. It’s amazing though how much you don’t have to know if you just nod.
A slipper clutch would probably have saved me an embarrassing accident 20 something years ago that broke my forearm in half. You best believe a stock slipper clutch was a _major_ selling point when I chose my first new bike in 20 something years last year. My downshifts are so smooth these days. I'm sure it's all thanks to that slipper clutch though.
Matt - on the chance you read this, is there any other provisions that need to be made to that clutch given the fact the engine is now powering a much heavier vehicle?
I don't think I've ever seen clutch plates with intact pads. Every disassembled clutch I've seen was a flat fuzzy mess with some marks indicating where the friction pads used to be.
Jag . . . where's the Jag? 😀
I thought this was going into your electric car. I was thinking "That looks like it's straight out of a sports bike; I don't understand why he needs this, and I'm not sure that it's rated for Tesla power, but I can't wait to find out" --- lol
Had one in my Ducati it was fantastic. I needed one in my Yamaha when I thought I was in 3rd downshifting into 2nd going into 9 at Brainerd. Turns out I downshifted into first and it flicked me over the bars.
Damn all hail the algorithm... Exept today i foundout i was unsubbed from you! Fixed that ASAP
Wow, that's pretty cool. I never knew such a thing existed! Although I have zero motorcycle specific experience... ;)
I always thought that slipper clutch occurs when because in a hurry you squeeze into your girlfriends slippers, then having problems getting these off again!
Putting a slipper clutch into my flat track bike was the best mod I ever did. The bike basically auto drifts now.
I'll see your Slipper clutch, and raise you my Dodges Slipping clutch. AHTA
So it's like a center diff, like the BMW viscous diff, only without the viscous. Huh.
yoyodyne... that company from Pynchon's The Crying Of Buckaroo Banzai
You know what slipper clutches dont like? Clutchless downshifts. The slipper clutch in my Royal Enfield is a bit rattly after a year or two of one handed clutchless downshifts.
has to do with the engine inertia. after shifting down the rear tire has to do work to get the motor up to speed from the new ratio. the slipper clutch helps nock down that ramp in speed and therefore torque at the rear wheel. it isn't doing much once it's up to speed there isn't enough engine braking to overcome the clutch springs.
the tiny fluctuations in engine breaking whale an engine is spinning at thousands of rpm kinda don't matter either. race bikes often run very high idles to minimize engine breaking. but the slipper clutch helps the tire not chirp whale getting the engine up to speed.
I own a slipper clutch but hadn't really thought about how it works, until now. Thank you Matt!
Doesn't a slipper clutch also limits the risk of over-revving on a downshift?
Lot cheaper to set the idle up 1-200 rpm. Throttle plate not completely shut= less negative compression.
Simple yet elegant mechanical solutions float my boat! I’ve never heard of this before but it’s on my favorite mech solution list from now on.
Yeah but why would anybody put a clutch on a slipper? 🤷♂️🤔
Next video - How a Slipper Clutch Works but in a drag racing car
exactly. That is the only place i have seen slipper clutches used. then again i am not a motorcycle nerd :)
@@uliwehner same here😀
Completely different slip arrangement; the drag racing setup is a centrifugal clutch. Would probably need to wait until Matt goes drag racing (with an internal combustion engine, not electric).
Thanks for the explain. These seem like a good idea and inexpensive so why are they not on more bikes? Is it only the more powerful ones that get the most from these?
You don't need this at all btw.. Just squeeze your left hand-- you can thank me later.
Kind of works the opposite way to a plated limited slip diff (on a car, not a bike obv). Balls on ramps!
I wouldn’t necessarily call drifting through a corner a bad day.
All hail
Yoyodyne...glad theres still Buckaroo fans out here.
Adjustmennt is done by varying the thickness of the steel plates.
Yoyodyne? Another Buckaroo Banzai fan, I see.....
"Cara kerja kopling sandal" anjir judul nya itu dong di gua haahaha Google translate apalah niii😭
Sorry Matt, I really don't care about the Jag, but I love these little detours!
And what if I WANT to intentionally oversteer of a clif huh?
Nice. Today I learned a new thing. 🤘🏻💀🤘🏻
I just wonder if you incorporate an arduino to control engine speed if it would do the same?
Cool! I learned something today.
All hailbthe algorithm
Best explanation I've seen so far. Thank you!
Somewhat unrelated, but I have a question about the Jagula (Tessuar?). When you originally installed the Model 3 motor/subframe/suspension the rear track was significantly wider than a stock Jaguar Mk V's rear track. Any idea of how you're going to bring the rear wheels/tires inboard?
I'm not, I'm going to widen the fenders by about 2 inches.
Buttloads is a legit unit of measurement, like metric fuck ton.
I cant believe this slipped my viewing enjoyment!
Gifted communicator brilliance, slick.
useful when you try to wear your motorcycle as a hat too. it has happened.
Yoyodyne - The Future Begins Tomorrow.
Nice to see how they work. Hail the algorithm! 😀
One day I hope to find a happy place for my ball bearing on a ramp.
Mah dude the fix is to drop a gear stay on the throttle and back it in
Seeing that rear tire coming up off the pavement gave me quite a bit of anxiety!
In what way is the effect different from a cush drive in a clutch (as used in my 1966 Norton 650SS)?
en.wikipedia.org/wiki/Cush_drive
There is no complete mechanical disconnect....the rubber (or coiled metal) springs just absorb some of the forces ( "damp" them down) and one of the best illustrations is the coil springs in some vehicle clutch plates......
You forgot to mention over revving while downshifting
Cool. I barely understood that but i believe you.
super fast, as always, thanks for the vid!
Dang dude
