Is This A Dry Clutch

Yes

 

Yes most definitely

 

Driza-Bone.. ;-).. until you start riding in the rain.

 

You need to take the pressure plate off to tell if it's a slipper.
What bike is it?

 

Looks completely standard.

 

...and you really should get a better cover for it.

 

does look standard, I would think of changing the spigot bearing in the middle, or at least check it's not binding. This isn't that bad a job, and documented on here and YouTube. On the plus side, it looks like you have a virtually new basket (gold bit) showing zero wear.

if this was mine then would treat to 1/4 of a can of GT85* as bound to be corrosion on plain clutch plates and oil within* is light enough that it will help not hinder the mechanical clutch action.

 

If it wasn't a dry clutch, those plates would be bathed in oil (hence a 'wet' clutch) and there would need to be a closed cover over it to prevent that oil spraying everywhere.

I believe dry clutches are used in racing as it's just easier and faster change a dry clutch than a wet one.

They also sound terrific

 

It's dry now but, by the looks of it, it hasn't always been so...
