Check out the Pro Moto Billet .com kickstands. I have one and love it. Only drawback is the price. It
fits perfect and operates perfect. looks like factory installation. Whatever tiny little bit it weighs the kx500 doesnt even notice. Sure is great when you are on the trails and want to take a little break. I have found that the trees are not placed where I need them, so the kickstand is a welcome addition.
