Look at Swomack's ride if you want to see how black turns out.  I think you can't go wrong either way.

Yes. Either is a better option than what Yamaha did with the unpolished aluminum. Nothing else. On the bike looks like this so I am not sure why you would do that. Chrome I think would look nice and the black makes it look mean. Either way you can't go wrong although I would powder coat the black instead of paint.

Had mine chromed before I picked it up at the dealership.  Still glad I did.   

Black Powder Coat is going to be easier to keep clean.

But won't it show the dirt more requiring cleaning more often?

I like the idea of chrome if you go stock. IMO

I plan to go the powder-coat black route when my bike is due for new rubbers...
