They do bend in all directions, stem is a heavy spring. Check them out at www.extremedualsports.com
i did use a piece of aluminum strap to make the mounts. Just cut them out and ground them to desired shape with a hand grinder. For the wiring I ordered the yamaha plugs from 12 0'clock labs in order to plug into stock harness. They are two wires so you lose the front running lights.
I also replaced the rears so I bought the led relay also which plugged right in to stock connector. For the backs i just cut wires and used bullet connectors.
I've been real happy with them thus far. I've ridden through some pretty thick overgrown trails and even dumped it a couple times and they have taken the beating.
