Yes that critter on my seat is a superb patagonic sheep skin.
It gives you great comfort on long distances.Warm?not a bit.It changes your seat in to a couch!!!!
The panniers rack is self done.It is a copy of the Tesch design.I had on my G/S in Germany.It is very strong,easy to put and take the panniers on and off.As the subframe from the L is very thin(allmost a joke!) the Tesch rack brings all the force to the main engine frame.
In this album you can have more detail pictures.
The engine plate is self made too.I took 5mm Dural.It is done wider to protect better the cases and levers!
I like the old Maier handprotectors.
