it's a bit sad that despite the explanations being so good, especially on the working of sequential gearboxes, that video does not explain at all the role of the clutch and as such fail to address the entire challenge of clutchless shifting or quickshifters... the concept of loading or unloading the transmission is not even mentioned. so here it is. as the video explains very well, to change gears, you need to make the slide gears move. to be precise one slide gear will need to leave a freewheeling gear, returning briefly to neutral, then a slide gear (the same or another depending of which gear ratio you are shifting between) has to interlock with a freewheeling gear to engage the new gear ratio. now to explain the idea of transmission load, when the engine is riving the wheel through the transmission, it does it by turning the input shaft, the input shaft is turning some of the gears, those gears are pushing with their teeth against the gears on the output shaft, one of them is interlocked with the dog teeth of a free wheeling gear, the gaps in that gear are pushing against the dog teeth and making that slide gear turn, it pushes on the output shaft with it's inner teeth, and so on so forth. when the engine is pushing hard on all of those, the gears are locked in place by the friction between their teeth, they can turn together, but cannot slide, and even just the engine power necessary to hold your speed is enough load to lock the gears in place. that's transmission load. on the opposite, if you're engine braking, the engine is now resisting the rotation of the wheel through the transmission, and the teeth are pushing against one another just in the opposite direction, that's a form of transmission load too. now, as we saw, it's impossible to change gears while the transmission is loaded, that's where the clutch comes in. the clutch simply allows you to disconnect the engine from the transmission, no power, no load, gears can slide and shift without resistance. there's actually no need to match precisely the speed of the gears because the dog teeth on slide gears are so large their interlocking with the grooves in freewheeling gears has large tolerances too. so the rotation speeds only need to be close enough, and just the motion of the oil in the transmission get their speed close enough when there's no load. now clutchless shifting is a technique that allows someone to unload the transmission without using the clutch and shift gears in that timing. when i explained transmission load, i said the transmission is loaded in one direction when the engine is driving the wheel, and in the other direction when the engine is slowing it down (engine braking). as a result, when you transition between driving and slowing down the wheel, your transmission is briefly unloaded. every time you are slowing down then open your throttle again, your transmission is briefly unloaded. every time you are speeding up or holding your speed and cut your throttle, you briefly unload that transmission too. and when the transmission is unloaded, the gears can slide and shift. there's one last part needed to understand how clutchless is properly done in practice. when you shift into a higher gear, the engine has to slow down (reverse for lower gears). and when you're doing clutchless shift, you cannot progressively release the clutch to allow the speeds to match. so to get a smooth shifting it's best to help the engine speed up or slow down. when shift gears up, you want to shift the gear in the brief unload as you close the throttle so that your closed throttle help the engine match the speed. if you do it the other way, and shift gears as you open the throttle, then on one side your throttle tries to make the engine go faster, and on the other side the wheel tries to make it go slower, and you'll will feel both forces knocking into one another in how rough the gear shift will be. and if you're downshifting, you need to do the opposite, use an unload pulse from closed throttle to open throttle, which is an entirely different timing and action. a common mistake that lead to a bad clutchless shift is to move the shift lever too late. when you're on the gas and briefly cut and open the throttle again, in your transmission, two brief instants of unloading happens: one when you go from throttle open to throttle closed, and one when you go from throttle closed to throttle open again. so if you're trying to shift up while accelerating, and you briefly cut the throttle to shift clutchless, if you're late now the gears shift when you go from throttle closed to throttle open, and you get that fighting between the engine slowing down because of the higher gear ratio and the throttle trying to make it go faster. finally, what a quickshifter does is simply to block ignition for a brief instant to produce the same effect as what you do by closing the throttle. many quickshifters don't support down shift because as i explained, down shifting requires a different action and timing, so if they want to only program the logic for one action they pick the most useful case: upshift.
I always use the clutch to go down the box on my cb750 k 6 Honda but quick up the box but my old cb 250 Honda was good up or down it had a 6 speed box I have my cb 750 from new still got and ride it 84000 miles and still going great all the best
@@sueplummer-x4k for various reason beyond the scope of us mere mortals, manufacturer make some gearboxes with slide gears that have "undercut" and/or beveled dog teeth, and this plays a lot in how clutchless will feel. smaller dogteeth are much easier to merge during clutchless. while beveled dogteeth can be made asymetrical on purpose and cause the downshift to lock more than the upshift.
Hey so you are saying while up shifting remain steady on the throttle & shift up or let off the throttle a bit & shift I have been experimenting with both on my full throttle Ducati scrambler down shifting goes very smooth up shifting sometimes not so smooth thanks
@@larrrevenga49 when up shifting, you should start with your throttle open and entirely close it while you shift. it tends to be easier when you're accelerating or kinda high in your revs. on a side note, if your ducati scrambler is recent it has a slipper clutch, which explains why downshifting feels so smooth.
I thought my bike have quick shifter. So I tried shift without releasing the throttle, which made it little bit tough to change gear. First I thought it was a budget type of quick shifter. Now I understand is was just a clutch less shifting. The video was really informative for me
You should be really careful doing this. If you pull the lever too hard you can bend a shift fork which... let's just call it a bad day tearing apart the transmission... You also need to be careful on your unload-load timing. If you get that wrong, you can damage or break dogs, or even the whole gear. Again - bad day tearing apart a transmission... The best option is usually an OEM quickshifter. With those, the manufacturer has already done the hard work for you and if used correctly the risk is minimal. With aftermarket ones... unless there is an OEM option (i.e. the ECU already has the programming for it) and you're just saving a bit of cash, it has to be tuned very carefully. Otherwise bad things happen... I've seen a gear broken in 3 pieces from a badly tuned one. Going back to the OEM option, strictly speaking you could make one yourself. On most bikes it's just a switch and a spring in a weatherproof enclosure. The spring is there to ensure there is enough preload on the lever to get the job done, but also not so much that you bend a shift fork.
@233kosta thanks bro. I been manually quick shifting for more than year at this point. I learnt it well and I can quick shift without clutch or even quick shifter itself. It basically need some practice and you will get use with that flow of shifting, it just need to shift when you just release the throttle and it should be done without any delay.
On old Harley Davidsons you have a clutch with a pedal. The gears were also shifted by hand with a lever, mounted at the fuel tank. Just for information.
@@wolfgangnapiletzki8480 Yea remember the ol suicide shifter? Those were the days. But we have grown wiser and more technical with each passing innovation. I did kinda like the left hand accelerator though.
Full of errors. In addition to the clutch pedal, I'm having a hard time finding the throttle pedal on my bike and the heater core shown at 7:19 is not to be found either!
The animation is fine, but LARGER scale, and slightly brighter / semi transparent - would be easier to understand. Slower in the shifting parts, would be also nice - slightly too fast - when shifting....
I didn't watch the whole video, so if this was covered, apologies in advance. What would be more relatable is a real-world test where a professional rider takes two identical bikes, one with a quick-shifter, one without, goes around a track like Laguna Seca for a few laps, and gets an average lap time on both bikes. Compare the lap times between the two bikes, and see if the QS-equipped bike does indeed make for faster lap times. I've been riding for 40+ years, have no problem at all using a clutch, a QS is just one more thing to go wrong. It's like driving a car, there's a definite difference between a true manual transmission with three pedals and paddle shifters. For the true riding experience, you need to operate a clutch in both circumstances.
So basically, By activating the quick shift sensor the current passing through ignition chamber cuttsoff and the crank stops getting initiation creating a engine halt where gears could be shifted ... Is that wht you taught or I have mistaken something . Please correct me if I'm wrng
With the quick shifter you cut off the ignition, in that moment you are taking the driving load off, stiftung the gears is now easy to do. Under load you can not shift the gears without destroying the transmission.
Its crazy i can disable the quickshifter on the 765 RS 2024 on dash it has up and down on the quick shifter its weird trying to get used to it, apprantly acourding to the manual for 765 RS and Moto2 model you can shift up with throttle on and the ECU will match the revs it self, its strange feeling as you skip out basic riding techniqes, the quickshift wont allow you to engage it without been above 4000rpm, amazing peice of tech
I dont think I like the fact of cutting spark only I would like to think it would cut the fuel as well I have a 1976 Honda ch 750 I jenly pull up on the shifter give the throttle a little bit of shut off and it just slips into the next gear ou so smooth must be doing something right as it is running as good as new with 84000 on the clock I use to work in a bike shop so I am the only person to have worked on it I use 10w40 semi synthetic car oil
This is very true! I cluchless up shift old bikes all the time. My 08 Tuono loved it. My DRZ prefers it. I even down shift without the clutch if the situation dictates. It’s all about load to the engine and what you plan to do next. My quick shifter in my ‘22 Tuono doesn’t care about that. On track I’m good, but on the street I don’t like the down shifts and up shifts are only smooth under heavy load.
@@dddon513Clutchless down shifting will destroy tranny and burn the clutch so thats not entirely true. Only works on upshifts👍🏼 and if your bike has a slipper clutch but no quick shift, i would suggest just pulling it in, really not much effort
I can shift my vmax that quick, without your equipment. Because I know how to ride. 2018 Yamaha Vmax 1700. I never use the clutch to up shift. Never feel the bike shift. butter smooth, and fast.
Nice animations. Some weird AI descriptions...clutch "pedal" on motorcycles? Yes, ..100 years ago.. Throttle pedal? Never, that I can recall. When shifting "clutchless", gear movement occurs when the TORQUE is reduced, NOT when the RPM of the two engaged gears is less than 1000 rpm, as stated. When a sliding gear and a freewheeling gear on the same shaft are engaged, they are locked, there is never any RPM difference, other than the few degrees of rotation allowed by clearances between the engaging dogs and slots. Either the quickshifter, or momentary closing of the throttle by hand, both just reduce the torque produced by the engine for a moment, unloading the gears and reducing friction enough for the shift to be accomplished. Clutchless shifts by hand do NOT require high force on the shifter...unnecessary and abusive. Get better! if that's how you do it. There if absolutely no increased wear if you do that quickly, but with no excessive force. In other words, with skill.
That's just bad for the engine. Refine your technique so that you won't have to hit the shift lever hard, just quickly. When you use proper timing and the right amount of throttle, you reduce the load on the dogtooth gears in the transmission, which allows you to smoothly shift up or down without using the clutch.
What you describe is NOT a known technique for anything to do with motorcycles. If you knew ANYTHING whatsoever about how to ride a bike or had any degree of mechanical sympathy, you’d NEVER do what you said! When you shift correctly, either with or without the clutch, one only needs to tap the gear lever and it works just fine. This obviously takes skill and practice to do properly. All that’s happening with your method is that the dogs are being severely worn and your clutch as well, since they share the gearbox oil and now you’ve got bits of gear dogs circulating in your gearbox oil. Awesome!😂🤪
These only work on race bikes that replace their gearboxes after a season. Everyone I’ve seen on a normal road bike used on track has destroyed the gearboxes after a couple of seasons.
Bas explanation, no gear box uses straight cut roothed gear, Only reverse gear used this type of gear, that's why it make that woer noise while engaged
Motorcycles are all straight cut gears. Helical gears would generate an axial force when torque is applied, and either acceleration or deceleration would separate the gears, depending on the helix angle. It would not work at all. Car transmissions generally use Helical gears, often not for reverse, but this is not a "rule", straight cut gears would work fine, but with increased noise.
You sir, are an absolute moron!! Before you go spreading your misinformation and general bullshit, it would be wise to actually check and confirm that what you’re saying is correct. EVERY motorcycle on sale uses straight cut gears! Have you ever even looked inside a bike gearbox, or taken one apart? Of course you haven’t! If you had, you wouldn’t have made such an asinine comment, simply proving your ignorance and arrogance.
I don't see any need at all for this device. Since my earliest days of riding motorcycles ( Honda, Yamaha, Kawasaki, Harley, Suzuki ) I have always shifted clutchless at will, without gear grinding. In fact, years ago I drove a '66 Corvette 4-speed clutchless most of the time, if I was not in the mood for all out acceleration. The Muncie 4-speed had excellent synchros and it was super easy to match engine speed to the next ratio I wanted just by engine sound alone. Quickshifter would seem to only benefit riders of a clumsy nature. However, the animation and explanations herein are very good. Would be excellent if slowed down a bit.
Riiight! So the fact that quick shifters are a piece of technology that comes DIRECTLY from Grand Prix racing bikes would obviously agree with your assertion that quick shifters only benefit clumsy riders!! You couldn’t be more wrong and incorrect if you tried. Please explain, how does cutting the ignition whilst changing gears act as an aid or be in any way beneficial to clumsy riders? If anything, it’d make it more difficult for inexperienced riders as it’s much easier and simpler to shift using the clutch, so it’s therefore far easier to make mistakes and mis-shift or similar with a quick shifter than without, especially for clumsy riders. Really not sure where you’re getting your info from but it seems opposite to what actually happens in the real world.
So in reality the quick shifter was developed for those who can't ride but want to look cool shifting fast without the use of a clutch! I have also seen and heard of many people destroying their bike by having a quick shifter installed on their bike! When I was in my teens a friend of mine had an old three wheeler with a broken clutch cable or something to that effect, we started it by bump starting and then you just went through the gears via clutchless shifting! To be honest it was simple and as long as you didn't act like a liberal shifting you had no grinding of gears! Yes basically shift it like a man!
The quickshifter wasn't developed for people that have poor riding abilities to appear pro. It was made for fast riders, making them even more fast. As I have developed such a system for my bike on my own, I can ensure you it makes a lot of difference, even the most skilled rider will not keep up to a similar QS-equipped bike, even when doing "manlike" shifts. Because at least he has to either roll of the throttle, or pull the clutch to shift. Otherwise the drivetrain isn't unloading and he can stomp the lever as much as he wants, the gear won't change. When using the first method, it takes around 0.1 - 0.5 seconds before full engine power is regained, mostly due to airflow inconsistencies. Because of slow throttle actuation, depending on the riders skill level, this gets even worse. A quickshifter doesn't alter fuel/airflow in the intake at all. It just switches off spark for ideally 2 - 5 revolutions, depending on how fast you are able to pull the shiftlever. The engine makes peak power all the way up to the point of gear change, and is there again immediately afterwards.
Fue desarrollado por y para las carreras en circuito, no para el uso diario. En MX no se usa porque los baches destensan la cadena que hace el mismo efecto que un corte de encendido. Eso, sí, la caja de cambios y tdos sus elementos, sufren mucho pero eso no es lo importante en las carreras, con mantenimiento exhaustivo y donde prima la eficacia.

These only work on race bikes that replace their gearboxes after a season. Everyone I’ve seen on a normal road bike used on track has destroyed the gearboxes after a couple of seasons.
I would never use this. I use a Rekluse auto clutch on all my bikes.
Clutch pedal
😅
Clutch pedal😂
Bas explanation, no gear box uses straight cut roothed gear, Only reverse gear used this type of gear, that's why it make that woer noise while engaged
Motorcycles do. Educate yourself before blurting misinformation
Motorcycles are all straight cut gears. Helical gears would generate an axial force when torque is applied, and either acceleration or deceleration would separate the gears, depending on the helix angle.
It would not work at all.
Car transmissions generally use Helical gears, often not for reverse, but this is not a "rule", straight cut gears would work fine, but with increased noise.
You sir, are an absolute moron!! Before you go spreading your misinformation and general bullshit, it would be wise to actually check and confirm that what you’re saying is correct. EVERY motorcycle on sale uses straight cut gears! Have you ever even looked inside a bike gearbox, or taken one apart? Of course you haven’t! If you had, you wouldn’t have made such an asinine comment, simply proving your ignorance and arrogance.
Ke roda??
I don't see any need at all for this device. Since my earliest days of riding motorcycles ( Honda, Yamaha, Kawasaki, Harley, Suzuki ) I have always shifted clutchless at will, without gear grinding. In fact, years ago I drove a '66 Corvette 4-speed clutchless most of the time, if I was not in the mood for all out acceleration. The Muncie 4-speed had excellent synchros and it was super easy to match engine speed to the next ratio I wanted just by engine sound alone. Quickshifter would seem to only benefit riders of a clumsy nature. However, the animation and explanations herein are very good. Would be excellent if slowed down a bit.
Riiight! So the fact that quick shifters are a piece of technology that comes DIRECTLY from Grand Prix racing bikes would obviously agree with your assertion that quick shifters only benefit clumsy riders!! You couldn’t be more wrong and incorrect if you tried. Please explain, how does cutting the ignition whilst changing gears act as an aid or be in any way beneficial to clumsy riders? If anything, it’d make it more difficult for inexperienced riders as it’s much easier and simpler to shift using the clutch, so it’s therefore far easier to make mistakes and mis-shift or similar with a quick shifter than without, especially for clumsy riders. Really not sure where you’re getting your info from but it seems opposite to what actually happens in the real world.
Bad explanation and animation 😂😂😂😂😂
Pls show him love
they has a views at least
So in reality the quick shifter was developed for those who can't ride but want to look cool shifting fast without the use of a clutch! I have also seen and heard of many people destroying their bike by having a quick shifter installed on their bike! When I was in my teens a friend of mine had an old three wheeler with a broken clutch cable or something to that effect, we started it by bump starting and then you just went through the gears via clutchless shifting! To be honest it was simple and as long as you didn't act like a liberal shifting you had no grinding of gears! Yes basically shift it like a man!
The quickshifter wasn't developed for people that have poor riding abilities to appear pro.
It was made for fast riders, making them even more fast. As I have developed such a system for my bike on my own, I can ensure you it makes a lot of difference, even the most skilled rider will not keep up to a similar QS-equipped bike, even when doing "manlike" shifts. Because at least he has to either roll of the throttle, or pull the clutch to shift. Otherwise the drivetrain isn't unloading and he can stomp the lever as much as he wants, the gear won't change. When using the first method, it takes around 0.1 - 0.5 seconds before full engine power is regained, mostly due to airflow inconsistencies. Because of slow throttle actuation, depending on the riders skill level, this gets even worse. A quickshifter doesn't alter fuel/airflow in the intake at all. It just switches off spark for ideally 2 - 5 revolutions, depending on how fast you are able to pull the shiftlever. The engine makes peak power all the way up to the point of gear change, and is there again immediately afterwards.
Fue desarrollado por y para las carreras en circuito, no para el uso diario. En MX no se usa porque los baches destensan la cadena que hace el mismo efecto que un corte de encendido. Eso, sí, la caja de cambios y tdos sus elementos, sufren mucho pero eso no es lo importante en las carreras, con mantenimiento exhaustivo y donde prima la eficacia.
"shift like a man" 😂 you old farts
Why there is Indonesian language
bla bla.... BS
Elaborate? 😂
