I've had my bike for 3 years as an everyday commuter living in LA and I always said I would finally lower it so I could flatfoot it. I never got around to it in LA, but I would love for once to be able to back pedal this stupid, heavy beast into a park spot up an incline.

Now that I'm back on the East Coast with all this slippery road salt, I nearly dumped it trying to parallel park because my tippy-toe slipped as I was trying to back up.
I had the same problem with my 2006 Z1000. At one point, I got so fed up and got rid of the 06 Z1000 and got a lower-standing Ducati Monster S4RS. It was great for a while, but I surely did miss the bulletproof ways (and larger tank) of the trusty Z1000. So, I got rid of the Duc and got my present 2008 Z1000. This time, I'm lowering it! Finally, before I get pissed off and do something irrational again!
Plus, these are fully adjustable. So, I can take it back up to stock if I want and I can adjust them with a simple twist of the wrist.
