Just thought I'd share this find for anyone who is interested.

The ones that are relevant to skorpions are 20516116-P32F.pdf for the P32F rear caliper and 20516558_68-P430-34C.pdf for the P4 30/34C front caliper. These are the ones I will be fitting to my bike over the next few weeks. Sorry if I'm being controversial mentioning Brembo brakes.
