Man i feel it's offical, just got my Desmo Owners Club card in the mail today, coolest thing ever, I wanna tape a picture of my bike to it!!! and the roadside assistance number there is very handy, though I hope I never need it 8) :-/
I got mine about 3 weeks ago. I keep forgetting about that thing. I have to put in the box under my seat pretty soon. The stickers are cool though. I'm still pondering on where to put my patch too. It would be cool to have the patch stitched into the seat.
