Heck no! I had a bright orange AFAM sprocket on my 14 for the last 4 years and I think it looked amazing with my anodized blue rim. The black/orange busa I am keeping low key with all aftermarket parts black. I like the shape of the busa and I don't want to interfere with the lines but if you go for bling GO CRAZY!! Just beware---if you start going with a colorful scheme, you might find later that you want to go another direction and then you have to buy some parts over again to get the effect your after. You can't go wrong with black. It matches everything and there is no problem with one part varying in color from another. The real way to do it if you get colored parts is get all of them anodized by the same company so they match perfectly.
Go for lightweight on your aftermarket parts. As far as sprockets, I think you will find Vortex aluminum to be the lightest rear sprocket. I am told Renthal might be even lighter. They are all pretty close in weight but go with aluminum rear and steel front. Vortex steel front is lighter than SuperSprox steel. Renthal steel front looks awfully dang light if the pic they show for the 530 pitch is actually the way they make it. Anyway, you go steel front and aluminum rear, you will go through two rears for every one front and then you will possibly want to change both sprockets and the chain all at once. Works that way for me.
I'm about to change sprockets and chain now. Planning Renthal steel front and Renthal Aluminum rear. If I get my BST rims, I'll go with a Talon aluminum rear sprocket but they don't make a Talon for the stock busa wheel. I think the consensus right now is to go with a ZVX3 for the chain. I weighed my new Z3D and it is a half ounce or so heavier than the old ZZZ I took off the ZX-14.
