9500ix is the cordless.
I have the escort 9500ci (blue LED display) on my zx6r, and the 8500ci plus (red LED display) on my k1rr. the 8500ci is what is pictured above, + laser jammers (not pictured).
Not cheap to buy it and install it hard wired to your bike. but it is much smaller, the display, than the wireless. I've never had a LEO notice any of my hardwired radar detectors (or laser jammerts) car or bike. it's illegal to have a laser jammer in CA, and usually if the LEO sees you have a radar detector, it's an automatic ticket, even though it's legal to have one.
the 8500ci plus is all you need. the 9500ci is top of the line, and the only difference is that if you pass the same spot with radar or lidar, it will automatically mark the location for you as a radar trap. the 8500ci plus doesn't do that. most of us ride around the same places and know where the LEOs hang out.
anyway I wouldn't ride without it. been with one since 2005, and honestly I feel naked without one. I know people hate the audio (in a car), or all the beeping and such, but for me, it's worth it. speeding tickets in CA start at $400. The newer models, you hardly get any false alarms, esp. if it has gps, it'll lock out the false radar reads.
I've only had my 1krr for a yr, and I've been pulled over 3x on it (pacing), and haven't gotten a laser hit yet, but gosh, radar hits, at least 6.
