This causes a greater parasitic loss through the clutch due to the resistance of the fluid and the increased mass of more plates. Dry clutches are pretty much the opposite, they are not as consistent and they don't last as long, but they cause less parasitic loss because of fewer plates and less rotating resistence.

Yep, sure do. Although the oil difference is minimal, and the weight doesn't have as much of an effect on handling as it does the parasitic loss in the drivetrain. Total weight difference is no more than a few lbs, if that.

this is what I was wondering pretty much. thanks.

No Problem!

The problem with dry clutch is that they drag badly when they heat up. The advantage is that they engage positively.

So, for a race bike, dry clutch doesn't hurt, but for a street bike, dry clutch bites the big one.

Good insight, Phi.

I have to have some use for some of this knowledge! Otherwise I'm just a dork and a weirdo.

Dry clutches sound like shit, but elitist folks with italian bikes like to think they sound nice.

I for one do not like a bike that idles with the sound of a can of nuts and bolts being shaken vigorously. Sounds retarded.

You should hear an OLD harley! They have open chain primaries, holy hell, it sounds like $50 worth of bolts in a paint-shaker!

oh god I cant stand that dry clutch sound. I'd be tearing my bike apart for no reason at all thinking the motor is gonna throw rods or something every 5 mins.

the funny thing is, the first time I ever heard a dry clutch was at Indy walk'n in with NtS and everyone... and I remember turning to NtS and being like... fuck... that bike sounds like SHIT...
