Hey Mark,
Wow, I had no idea you were so... um... well... mature.
I don't think you need to worry about the black swingarm. I think that is one of the magnesium swingarms that the factory rider's use to drop a few pounds off the bike. These are checked out to the factory riders - I don't think the average guy could get one at any price - and if you could get one, I don't think you would mind it being black!
BTW - the evans coolant doesn't boil and doesn't expand - but it doesn't transfer heat as well as water either... You can run a lower pressure cap and it does make the cooling system less prone to failure. However, the engine temp may be hotter when running evans and it wouldn't be apparent to you.
