Hey, not sure if it helps but I just bought myself a tatty 2007 Superlight and gotta say I also love the look of the bike although haven't ridden it yet wanted to sort some things on it first. Theres actually as fair bit of stuff on ebay that's not made for the bike but with a little bit of work can be made to fit or already does!
Ive also been looking at fitting a single seat to mine and getting rid of the back mudguard for a wheel hugger will look great but for now keeping it as it is simply because I want to make my own from scratch.
Only had mine two days so far and only cleaned it a little and done a respray heres a before and after of mine, hopefully within the week it will be looking ALOT more how I want it and more custom for me
heres the day I got it http://imgur.com/a/DA3wm
and heres two days later http://imgur.com/a/7aiDv
still ALOT to do for me but looking better ill let u know if I find a seat that will fit straight on.
