I'm considering buying aftermarket brake lines for my 400EX. Does anybody sell kevlar lines for quads? I'm aware of the stainless steel kits. Where do I get the red color brake lines that I've seen in magazines on some race quads? Do you feel it's worth spending the money on the rear line? Thanks.

 

I bought my stainless lines (front and back) from white brothers. They have them is a bunch of colors..I opted for the chrome.
They made a good improvement over stock. The brakes no longer fade because of line expansion.

It is a bit more difficult to ensure that you do not get any bubbles during the bleeding process...But I like them alot.
