Re: Dry Clutch vs Wet Clutch

Hi All,

I need a fast response that is fact, not just opinion. A car guy was just telling me that bikes use wet clutches while cars use dry clutches and that you can ride a wet clutch for LONG periods of time without damage.

Seeing as I'm not mechanically knowledgable and I don't know #### about the difference, can someone explain this too me further? Links are cool if you got 'em. yes, I know some bikes use dry clutches (like Ducati) but that's the extent of my clutch awareness.

Thanks.
J.

Re: Dry Clutch vs Wet Clutch

wet clutches are in there with the engine oil, so the oil will cool the clutch to a certain extent.

A dry clutch is just dry friction... Its not in a medium other than air...

Re: Dry Clutch vs Wet Clutch

Yeah, people at the MSF encourages clutch riding for newbies. They always make a point ot say that their bike's never had the clutch replaced, after so many people abuse them.

Re: Dry Clutch vs Wet Clutch

Yeah, that's kinda how the whole topic came up. I belong to another board (where strangely, I am one of the more experienced riders) and this guy joins after buying his first bike. He mentions that he doesn't downshift and has a hard time putting the bike in first after he coasts to a stop. Sooo... I tried to find that 'how to shift' article I read a while back but ended up just re-writing the thing because I couldn't find the original. I gave both techniques, with and without clutch... and this new rider says he knows how car clutches work and that you can abuse motorcycle clutches because they are wet and not dry like cars. He then agrees to test out 'my' method of shifting without a clutch. *sigh* I hope he doesn't think I'm the only one that does this.

Anyway... I gave him the info, what he does with it is his business.

Cheers, and thanks for the answer ccwilli.

Re: Dry Clutch vs Wet Clutch

he should be in clicking into first before he stops... Bike trannies need to be moving to shift. Its very hard to get one to down shift without rocking the bike back and forth if you do that...

Re: Dry Clutch vs Wet Clutch

Especially VFR's!!!

Bad form to stop with the bike in a gear other than 1st. I think that's one of the basic MSF skills.

Downshift, break, stop, left foot down (or something like that).

I used to click the gears on my bikes without the clutch until they started popping out of 2nd gear while under decell.. sure.. it's cool and racy but man.. my VFR and F2 both suffered for it....

Re: Dry Clutch vs Wet Clutch

One is dry and the other is wet.

Dry clutches are easy to tell from wet (on bikes that is)...You can tell by the Gawd-awful racket emanating from the tranny on a dry clutch...ala Ducati.

Stegen, read above. That rattling noise is the dry clutch.

Ya, thanks guys. I know that the Dukes have dry clutches, I was just asking what the mechanical difference was. (Answered, one is submersed in oil, the other is not) Are there any other mechanical differences? Also, what are the benefits of one over another?

Re: Dry Clutch vs Wet Clutch

Not sewing machine, more like trash can lids being banged together in a funny car idle sort of rythmn.

Dry clutches are used to reduce internal engine losses from friction due to oil cavitation. In a perfect world they are exposed to the air stream and are kept cool. In real life, they overheat on the grid while the starter is looking for his sunglasses and generally become useless after 20 seconds of 'dragged engagement'. They require frequent replacement and (as noted previously) are very noisy when disengaged. Every GP bike I have ever seen has one and I used to replace my TZ clutches every other weekend to avoid surprises.

You should make one point perfictly clear:
Up shift without a clutch all day long, no problem. But please use the clutch for downshifting. BTW, there is NOTHING wrong with using the clutch on every shift. It's much easier on the transmission.
