Looks like quite a nice conversion for a SS especially if someone was considering the underseat exhaust route like Senna3's, looks like they have put the whole in the back in just the right place and also allowed for the heat to escape
Just doing one of these up myself. I got it of fleabay, and it was in a bit of a state, all chipped and battered.
Been working on it bit by bit when I get time. Made a new seat pad from a sheet of formed stainless steel and foam with leatherette cover. 3rd attempt finally came off.
Coat of white on at the moment to show up any missed defects. Nearly there filling, sanding, filling etc...
Ready for red and Corse stripe soon.
Got an Aprillia 250 rear light which fits nicely in the hole at the back.
So if you are considering this seat, I can recommend it, but be prepared for a bit of work on fitting the light and making a better seat pad than the foam one I have seen before.
