I like all of them, lol.
But my top favorites, are:
2003 Yellow fronts & black rears
1999 Red fenders with black tank/radiatior
I believe 97, the black plastics, red radiatior cover, with the gold rims. I find it attractive, lol.
There are so many its hard to choose. Like the all yellow anniversery addition. But i guess those are my top.
In canada, the orange and red ones are just dead sexy lol. I wish we had them in the us.
