I know lorica isnt like vinyl. It is permeable and does not crack with age. But does anyone know if it can be dyed?

no idea. call Sidi

I believe it is dyed from the factory in the actual process of making it. I'm not positive however.

You should be able to strip and paint it. A member painted some dainese boots over here http://www.ducatimonsterforum.org/index.php?topic=50948.15 . The pics are gone but he used Angelus leather paint.

I had done it before too but  from black to black. When my Vertigo's got IZ_ and faded looking I stripped 'em with denatured alcohol (there wasn't much finish left) and painted them black again. They turned out a little too shiny so I dulled them with 3M Scotch brite. they looked more like leather than they did new and lasted about 8 thousand miles so far.   

I did it again from black to red on the front flex panel to see how it holds up. This time I stripped it with acetone like you would with leather-- bad idea. It made it a little rough like suede but I was able to sand it smooth.  not sure if stripping is necessary because Lorica is a lot more porous than leather.  Alcohol takes the factory finish off anyways.
