Hopefully some of our UK members will chime in to help you.
Here in the States, our SP1 color scheme was totally different than the Euro model.
And that also applied to the SP2 color scheme as well except maybe the '05 and '06 model, where I believe you folks also received them in black?
SP1 tanks even in the uk are like trying to find rocking horse poo!!! the ones you can find are overpriced and usually battered to hell. A new one is about £400 I believe. Look at Lings Honda as they have a very good online parts system where you can get anything for your SP1 still. I have used them quite a bit and been very happy. http://www.lingshondaparts.com/honda...alogue_M01.php
