I've been making the seat for a couple of days. I made the seat base from 3mm aluminium sheet, which I cut and bent into shape. I want this seat to be rubber mounted to give it some cushioning, so I've fitted a hinge at the front  for it to pivot against. I drilled holes all around the edges for the rivets which are going to secure the leather cover on.

When I fitted the base to the bike and sat on it it was clearly flexing quite a lot and could permanently bend if I was sat forward enough and hit a big bump. So I made a strengthening bracket and bolted it to the base.

Before I finally fit the seat I wanted to relocate the electrics so they're hidden from view. Originally they were mounted on the side of the bike, so I moved them so they're under the seat, between the seat rails. Luckily all the electrical items fit between the seat rails while mounted to their original mounting plate so it was just a matter of making a couple of little brackets and I'll have to make some longer battery cables to the starter relay too.This'll make the bike look nicely clean and stripped down with a big old space under the seat.
