There are lots of mods available for the Z1000. I'll just cover the most commonly changed ones. Feel free to add anything.
The stock mirrors are one of the biggest complaints among Z1000/Z750 owners. With the stock mirrors you get a great view of your elbows, and they are pretty ugly. There are a few options out there incase your interested in fixing these problems.
If your looking for a cost effective way just to improve the view of what's going on behind you motospecialties.com makes a nice mirror extenders that moves your mirrors outward an inch or so, and up higher a little. They bolt in to your existing mirror mount holes. Supposedly, these work great.
You could also opt for nice billet mirrors. A lot of cruiser/chopper mirrors will bolt right on to the Z. Some others require adaptors. These mirrors can get extremely pricey, and in most cases dont do much for improving your rearward view.
Bar-end mirrors are some of the most common mirror mods done to the Z. They give the bike a lot sleeker appearance, and rearward vision is usually improved greatly. Depending on how the mirror mounts to the bar-end, vibrations can make it difficult to see whats going on behind you. Keeping the barend mirrors, or fulling the bars with BBs can help reduce the vibrations a little.
There are a few companies out there that are making taller windscreens for the Z1000. Being a naked bike, higher speeds can fatigue you alot quicker with the wind pushing against your body all day. Zero Gravity makes a few different models of windscreens for the Z1000. Givi, Barracuda, and Kawasaki also offer taller windscreen replacements.
Lets face it. The stock exhaust on the Z1000 is either a love it or hate it accessory. While being different in the looks department, it really affects the performance and handling of the bike as well. The Z1000's stock exhaust is VERY restrictive and heavy. The stock exhaust (head pipe and both cans) weigh 40lbs! Most full aftermarket systems only weigh 10 to 15lbs total. The reduction in weight becomes extremely obvious once you have made the change. The aftermarket exhaust will also allow for several extra ponies, unleashing some real power. Dyno charts have slow gains over 10hp to the rear wheels with a tuned power commander, exhaust, and K&N filter.
You could also opt for a set of slip-ons. They usually cost more then a full system since the Z1000 has two cans. The stock cans weigh 15lbs a piece. So you will see a decent reduction in weight with slip-ons as well. As well as a small gain in power.
The other big factor is the sound. The stock pipes almost make the Z1000 sound like a huge weedeater! Its almost embarrassing. Slipping on a nice set of cans, or even a full exhaust will make the Z1000 growl a beautiful note that will send chills down your spine.

Crash Guards\Frame sliders:
There are a few different styles of Crash Guards or frame sliders available for the Z1000. The first kind are frame mounted sliders. I have a pair of shogun frame sliders that attach to the engine mounts right behind the radiator. These are very easy to install, just remove the bolt (one side at a time) that holds the engine in and install the sliders and mounts back into the holes that engine mount holes. I can loosen the radiator to allow yourself a little more room to work, I was able to install the sliders without loosening anything up.
Another style slider is the type that replaces the engine covers. Just remove the stock side covers and install these. I would highly recommend using the two sliders together for more protection.
