Honda Dual Clutch Transmission

[jarjarlol]

clutch up wheelies gone, hard launches without having to activate launch control gone, reving at cute girls on the street gone, slowly retardising motorcycle riders exactly how car drivers with automatics have in America - Check

[bukakee1]

So what a Dual Clutch really means is, so easy Kim Kardashian can drive it.

[ronmann606]

thats pretty fucking slick I must say

[Jeepus80]

call me old school but ill stick to my old 929

[t545o]

its not the same thing,,,

[corruptorCEREBRUM]

@t545o Fuck you and the lawnmower engine attached to your bicycle.

[t545o]

@corruptorCEREBRUM just buy a scooter then. it would be the same pleasure you'd get from this. there are things that never should change...

[corruptorCEREBRUM]

@t545o A scooter? With its belt-drive and CVT? You can't compare it to a DCT. Read up about the VFR1200F's semi-auto dual-clutch transmission. It makes use of friction clutch plates (not a torque converter), and therefore it retains engien braking, and so it's got the same performance as a manual transmission. And best of all, the DCT can shift gears and actuate the clutch at light-spee, faster than any human ever could. That is the advantage that this system has over any other transmission.

Just Like my Montain bike!

[MomchilMTz]

everybody hwo knows how to ride a motorcycle...

[evanparker]

who in the fuck accelerates on a motorcycle like this ?

some slooooow shit here honda.

[euheide]

@evanparker the shifting depends on your acceleration. In this case the rider's accelerating slowly ;)

[corruptorCEREBRUM]

@euheide That Honda VFR1200. What happens if the bike comes to a stop? Does the clutch automatically disengage? And when you're starting off, does the clutch engage itself?

[euheide]

@corruptorCEREBRUM yeah, it's all automatic, even if it's in manual mode, automatic will override your manual commands if you're not doing it right ;)

[corruptorCEREBRUM]

@euheide Thanks for the reply. Damn! This is indeed the future of motorcycle transmission - if only manufacturers could start installing this system on all production cars (not just the few exotic sport cars). Even so, I don't believe it will render conventional manuals obsolete. My dad is actually interested in the VFR1200 semi-auto, and I'll mention your comment to him. I ride an 09 GSX-R600 (belongs to my dad), and the dual clutch system makes the Gixxer's gearbox look like a paperclip. ;-)

[euheide]

@corruptorCEREBRUM thanks for your comment! Yeah this system is spectacular, although I must say that the standard transmission model is also spectacular ;). having the auto-transmission is a bonus. Unfortunately for me, you have to choose between one or the other at the dealer. I would prefer a model in which you'd be able to ride normally (completely manual) but also semi-automatic and fully automatic because I also enjoy using the clutch sometimes even though not always ;)

[corruptorCEREBRUM]

@euheide @euheide No problem. See the big problem with manual transmissions? They LOSE power during the gear-shift interval. While the dual-clutch transmission transfers power constantly (8 milliseconds for a gear-shift). If you perform the experiment uphill, you'll notice the difference. Manuals will tend to "lag behind" while the semi-automaitc DCT keeps a constant acceleration. Check out a video called "how does BMW M3 DCT(double clutch transmission) works".

[corruptorCEREBRUM]

@euheide

1. Haha, I was about ot mention that too. It would be even better to have a dual-clutch transmission which combines automatic mode, manual mode, with a fully manual sequenial transmission. In other words, the bike will have two seperate transmissions (DCT plus manual sequential) in one, and you can toggle between any transmisson you damn well please! The DCT will engage the clutch electronically (in manual or automatic modes), but you can choose yet the third mode ("Fully Manual")...

[corruptorCEREBRUM]

@euheide

2. ...since the bike will also have a manual lclutch lever and geasr-shift lever at your left foot. It would essentially be the transmission equiavalent of a Swiss Army Knife. Note that Formula 1 cars are single-clutch semi-automatics WITH a clutch lever (used for a standing start). The gear-shifts and clutch are performed by the computer, but when you start off, or come to a stop, you must use the clutch lever.

[corruptorCEREBRUM]

@euheide

3. The problem is that the manufacturer must take weight and cost into cosideration. A single vehicle cannot have all possible transmissions (otherwise the vehicle would effectively be packed with a CVT, manual gearbox, plus DCT, plus torque convertor, plus H-shift manual, plus friction clutch plates, etc, and then give you the option to toggle between each transmission at will). That would be a mechanical nightmare! Dual-clutch transmission is the best of both worlds. ;-)

[euheide]

@corruptorCEREBRUM You really know your stuff man! ;) After reading your comments I realize the impossibility to make that wished system heheh. And since it's so efficient and fast changing gears (no power loss etc), I would probably (almost certainly) choose it over the manual model :) I mean... It's too bad that it doesn't come with completely manual operation but the advantages clearly outweigh the losses, by far, in this system. :)

[euheide]

@corruptorCEREBRUM and I'm sure this is a thing that will be on many riders minds when they consider buying the automatic transmission version :P

[corruptorCEREBRUM]

@euheide Haha, exactly. During this sequence, the DCT disengages the first outer clutch whilst simultaneously engaging the second inner clutch (all power from the engine is now going through the second shaft), thus completing the shift sequence. This sequence happens in 8 milliseconds (aided by pre-selection), and can happen even with full throttle opening, and as a result, there is virtually no power loss. This thing can shift gears faster than any human ever could - that's the ADVANTAGE.

[euheide]

although in the end, the automatic version is probably the best if you have to choose between the two. If the system isn't problematic mechanically speaking that is :) but being a Honda I trust that's not going to be a problem

[corruptorCEREBRUM]

@euheide I agree with you dude. CHoosing automatic (but Sport Mode) is the best option. Oh, and me and my dad visited Honda Kyalami (a popular dealership here in Cape Town), and he test-drove the VFR1200F (DCT). The VFR1200F (manual) model costs R149 999 (SA Rand). And guess how much the VFR1200F (semi-auto dual clutch) costs? R189 999. Fuck! Expensive yes, and my dad said if we decide to purchase it, he must SELL the GSX-R600 and add the difference to buy the VFR1200F. Tough decision. :'(

[euheide]

@evanparker it can be slow but it can also be lightning fast ;) That's what's awesome about it. It's what common sportbikes don't do so well but sport-touring bikes are so good for.

[corruptorCEREBRUM]

@euheide I agree. With 8 milliseconds of shift-time, technically speaking, if you were driving a Yamaha M1 with a dual-clutch version on a straight-line of road, you could effectively outrun a manual M1. I believe Honda has finally taken Formula 1 technology and made it even better - and then put it on a motorcycle. I guess you can't get any more advanced that what this technology already is. The next step would be to find some exotic material to make near-indestructible clutches.

[corruptorCEREBRUM]

@evanparker You'll be surprised how fast this thing can shift. If you have two of the exact same bikes (say, two Yamaha R1's) and the one is manual and the other one has a semi-automatic dual-clutch tranmission then, theoretically, the dual-clutch model would be much faster than the puny manual. The power of the system is the fact that electronic equipment can react much faster and more precisely than a human, and takes advantage of precision of electronic signals to allow full clutch actuation.

[dai1000rr]

確かに上級者には必要ないし運転の楽しみは少ないシステムだが、­半身に軽度の障害とかある人には助けになるシステムかもしれない­。ステップが足に刺さって膝は動くがその先はうまく動かない人と­か。あの人は右足だが。バイクの特性上、半身に大怪我をする可能­性はどうしてもあるからな～。

[Gusoh]

チートも甚だしいｗ

幾らになるんだろう・・・

[ekko933]

Put one on a Honda Rebel and I'll buy it!

[RastusFuckhai]

Shifting gear with your foot is for assholes. Stick with your Gen 3 VFR is get the fuck out of the way of the future.

[corruptorCEREBRUM]

@RastusFuckhai I just couldn't agree any further. Thanks for that comment. I ride an 09 GSX-R600 (my dad's), and often I use my 150cc scooter for my daily travel - simply becuase I just hate using hte clutch every time I stop and go - riding bikes is about not having to worry about it, I want to enjoy the ride, and not have the inconveience of controlling clutches (leave the dirty work for the computer). I'd take the VFR1200F dual-clutch transmission any day! It's just too expensive. :(

[1200686]

MAZDAzoomer さんやRollingThunder6969 さんが指摘してるように、こんなにのんびりシフトチェンジしてる­のは、余程の初心者か暴走族くらいのものですよ。

大型免許もってるくらいのレベルなら、普通は一瞬でシフトチェン­ジ済ませてるはず。

[utic9902]

あんまり関係ないことかもしれないが、シャフトドライブではない­か？カムギヤっぽい音は、そのシャフト由来では無かろうか？

[TheToekutter]

Sooo, according to my estimate from watching the tach and speedo it can do about 185 mph if it could hit redline in 6th. =)

[corruptorCEREBRUM]

@TheToekutter My dad test-drove thae VFR1200F (semi-auto DCT) yesterday. It cannot hit redline, because the computer automatically upshifts even before you reach redline (even when you're riding in Manual Mode). Not that it's a problem - it's just a safety precaution, to prevent you from damaging your engine.

[keithwall]

awesome! anything that gets more people on 2 wheels is great! hopefully it's low maintenance

[arrow303]

Lame! Lame! Lame! A new invention for the terminally lazy! It is not difficult to shift gears but first you must put your brain into gear. This is just for those too lazy to do that!. A total waste of time.

[Bovineguy]

I would buy one in a heart beat. I'm also not terminally lazy, I wrecked my bike in '07 shattering my left arm, lots of metal in there now. The pain in my left arm from squeezing and holding a clutch it unbearable. I have no problems on a scooter because there is no clutch, I would love to be able to get on a real bike again. I expect I will someday.

[corruptorCEREBRUM]

@Bovineguy Very well said. I ride an 09 Suzuki GSX-R600, and I've also got 150cc scooter. Honestly, holding the clutch at a stop and having to pull the clutch with eah gear shift is painful and inconvenient. I would rather go for the VFR1200 with DCT, so the computer can actuate the clutch in a split-second, faster than any human could. So that means far mor rapid gear shifts, and therefore your bike will be almost like an F1 car, beating everyone who is still using manual clutches.

[corruptorCEREBRUM]

@Bovineguy Sorry about the wreck you made - it happens. I've never crashed or fallen off my GSX-R600, but I have fallen off my 150cc scooter (leaned too far into a corner and it caused a lowside). But I'd take dual clutch over a manual bike any day - problem is it's so expensive. I await the day they eventually put DCT into other production superbikes (such as teh GSX-R600 or Yamaha R1). So even beginners can enjoy riding superbikes with no need to worry abotu clutches or stalling the engine.

[corruptorCEREBRUM]

@arrow303 FUCK YOU old-fashioned cunt! This new technology is reserved for people who have the money to afford it, so fuck off with your traditional manual 125cc motorcycle. I feel sorry for faggots like you who still have the pull the clutch and take a few seconds to shift gears, and to top it off, during your gear-shift interval you lose torque in the process! Haha, useless bigot. This new dual-clutch transmission has the advantage of having CONSTANT acceleration.

[corruptorCEREBRUM]

@arrow303 Oh, I ride an 09 GSX-R600 to university every day, unlike you, and my dad has plans on purchasing a Honda VFR1200F. Show some respect for superior technologies developed for the affluent people among us. By the time you're busy pulling the clutch on your fucked up moped, a DCT motrocycle already went to the next gear in 8 milliseconds, faster than what your brain can process information.

[RollingThunder6969]

日本の大型２輪AT限定免許は650ccまでなのでVFR120­0には乗れません。

MTシフトの動画はわざと遅くしてるのでは？

車のHパターンより操作が遅いわけ無いし。

[NISSANvsH0NDA]

AT限定でもOk？

俺バイクのらんから良くわかんないけどさ、バイクのギアチェンっ­てこんなに遅いのか？

車のギアチェンより遅く感じるが。

[revtune]

It's like the VW DSG or Porsche PDK dual clutch transmissions for cars. Curious to see if they use this in racing in the near future.

[corruptorCEREBRUM]

@revtune They already are using variations. Look at Formula 1. It makes use of a single-clutch semi-automatic transmissions, where the computer electronically performs gear shifts and clutch actuation. However, there is a manual clutch lever used for a standing start or when coming to a stop. I don't know why they bothered putting one there in the first place...
