The Kuoba links are exactly what we used to lower the DRZ400sm. Very easy to install, it only took about 20 minutes. We also shaved the seat, $40. It's an '06 and they are running pro-taper like bars already so we could only raise the forks in the triples by about a centimeter.
The bike is really low now, good enough for my gf to stop on hills and feel confident, too. It made a HUGE difference.
