Jose -
Seat is home made from fiberglass see below. Colour is something I concocted with the local auto paint shop, a very dark pearl blue with large blue metal flake.
Clubman bars are perfect for me as I much prefer the forward lean to bars over the standard upright seating position. Picture below showing diminsions. I would recommend a slightly wider bar to provide more room between brake banjo bolts and the instrument cluster. I have not changed the cables nor hydraulic lines as I was able to route them without any kinks however shorter front brake lines would be desireable. I have a set of braided front lines on order.
I am still experimenting with foot peg position however at this stage it feels OK. I tend to ride with the balls of my feet on the pegs so perhaps if the pegs were rearward by 75-100mm it would work also. I'll ride more miles before making any changes.
Seat construction:
My friend Mick making the base plate to fit frame tubes-

Fitting a ring around the base plate to give illusion of a flat frame for lower rear end-

I can't remember the brand of the mirrors but there are plenty out there which will do the job, just a matter of what you like.
