Made by Classic Industries, this hitch is designed to fit the modern Kawasaki Concours 1400. It is a black powdercoat hitch that can be removed in a couple of minutes if you aren't planning to tow.
Expensive? Yes, but it's well made and designed to handle any trailer or camper that you can safely tow with a bike. I use the same brand, and almost the same design hitch on my own Honda ST-1300. I've had mine for about four years now and it is standing up well to both use and exposure to weather.
(And, it's imported from Australia, so about a third of the price is the shipping expense.)
Installation is pretty simple. It requires creating small slots in rear fender under seat to allow the seating of a pair of brackets. Otherwise, installation is fully bolt-on. Includes directions and all required hardware along with 1 & 7/8" ball.
For a complete solution, pair up your hitch with one of our Motorcycle Trailer Wiring Harness.
