My big bugbear is that I can't find the nice rubber nose cone like Thorn uses on the P55s, or even mudflaps (the P65s, sourced online from someone other than SJS, came with neither). Any suggestions?
I can tell you SKS' US office doesn't stock the same model or replacement parts, and I came up short in Germany,
Nice work, Sam. I'm not surprised you came up short, Dan, looking for "mudflaps" and suchlike. The Germans call the component a "spoiler" or a "gummispoiler" because it is made of rubber.
Yo, Sam, If you can't get it from SJS, here's a reliable German dealer with stock:

The one you want for P65 is SKS (Hersteller = Manufacturer) number 10187, which is the Typ(e) 3 on that that page.

This is the one I have on my P65.
There's also a different design of mudflap (gummispoiler!), with longitudinal design details, and what seems to me -- strictly from the photographs! -- a superior design in that it guides the water down rather than backwards like the one above. It is said by SKS to fit, but only up to 55mm. I have no personal experience of it, so anyone who orders it is on his own. This is it, from the same dealer:

I don't know which nosepiece you're talking about, but you should be able to find it on this page:
