collectible to me means very rare or will go up in value.
examples- race bikes ridden by foggy, bayliss, etc
-maybe- some of the special edition bikes with very small production-MH900, Bostrom 996, Capo M695
the bikes shown in the ducati museum are good examples
get a bike because you like to ride it...the value is in the enjoyment of its use
btw- i have seen bike outside of a museum i would consider collectible
Silver 916 special made at the factory #1 of 1. <drool>
I have a white 2007 s4rs and my father has the 2008 tricolore. Side by side they appear identicle except he has a little numbered badge and I think a plastic chain guard I don't have. But I looked hard and that was all that was obvious on the outside.
That said, his is more valuable than mine. And if you wanted to put one in your living room on a stand, or in a museum, as the 'baddest monster', the end of the era, the last of the round headlights, the most refined bike from an engineering standpoint... I would argue THAT is the bike to have. In fact, that is pretty much the whole point of that bike. It was by definition a collectors bike; they made 130000 mosters but they only built 500 tricolores... and they make a point of which one you have.
...but unless you have enough money for 2, I'd do what I did; get one and ride the **** out of it
In short, to me, the 2007 and the 2008 are the same but the 2007 isn't worth collecting... It's not the last year and it is not a numbered limited edition. But it is just as good as a Tricolore on the road... Plus, I like my paint better
