Dry plate clutch v multi plate wet clutch

There's a sort of truth... Wet clutches are more durable, certainly, the oil helps keep the temperatures low and more evenly distributed, and pick up as you let the lever out is smoother too. They do still wear and fail when abused though - older Yamahas used to be notorious for it, and I remember when speed testing them in the 90s you could only do a few quarter mile runs before they'd permanently give up.

Dry clutches generally last less well though, but the point of having them is they're smaller and lighter. A wet clutch needs to be big with more clutch plate area because the oil lubricates the plates as well as cooling them, so you need more area to offer the same amount of grip as an equivalent dry clutch. That reduced weight and size of the dry clutch is important on high performance bikes, so you get them on race bikes and a few road bikes, most notably Ducati superbikes. In fact in general use, Ducati dry clutches don't feel a lot different to wet clutches, you can slip them when pulling away normally just the same, and they'll take a few fast getaways too, especially if you let them cool again in between.

Car clutches are nearly all dry, because they have much more torque than bikes (it's torque that determines clutch size, not power) and would have to be obstructively big if they were wet. But more pragmatically, dry clutches are cheaper and they work well enough in most cars anyway.
