tail piece
 

Does anyone know if I can still buy a single seat tail unit ? If so ware from?

Whaccessories.com i believe has some, may take a little fab work to make some work... if your looking for stock look, i know webike japan still has magical racing bodywork, not sure if they have the tail piece but take a look.

Sharkskinz has 2 tails.

One uses stock seat, makes it look like a single.
STREET SOLO TAIL needs foam pad (VTR1000)

The other needs foam or whatever you create.
STREET SOLO TAIL uses stock seat (VTR1000)

I still see decent ones on Ebay now and then.

check out bespoke carbon in the uk, they've just started up in the uk, they're in the process of building their website, you can contact them via facebook, you can buy carbon fibre or fibreglass, you can even have different coloured carbon fibre.

Awsome, thanks for all ur help.
