I'll do you one better. I just tore mine down to put the ThermoBob in and found a similar, if not identical, leak to yours. Mine is a 2013, too. However, I just bought mine NEW from the dealership about 2 weeks ago (yes, 2 years old on the showroom floor) and has, wait for it, less than 200 miles (16 when I bought it and I put those on it last year on a test ride). Nice.
I came here tonight to find out what the problem might be but pretty sure it's the seal from the impeller and pump body to the engine drive shaft. And I guess that's what it is. NUTS! Was really looking forward to installing my ThermoBob so I could continue the break-in period....2 weeks and less than 200 miles...sad sad sad.
For those not familiar with water pumps in general; there is a shaft from a drive force (accessory belt, usually on cars/trucks/etc., or a direct shaft, obviously on the Versys and any non-belted engine) to the water/coolant pump which is just an impeller in a sealed container connected to the coolant system. Obviously the liquid needs to stay in the pump body yet the shaft must pass from the outside of the body to the inside. Coolant must not pass from the inside to the outside so there is a seal. There is commonly a void outside the pump body seal, between the seal and the drive force (a snout on the GM 350 water pump, for example, which sticks the belt pulley out to the belt plane, or, in the case of the Versys, apparently a void between the pump body and the engine block). Furthermore, there is commonly a weep hole placed so that coolant which leaks past the seal has a convenient place to discharge where it can be viewed, either to release the fluid or to simply allow easier troubleshooting, but probably both. In my third picture you can see the weep hole which appears to be the source of the fluid. I'll have to go back and highlight the image to make it clearer, though. Jeez...2 hours messing around with PhotoPaint and PhotoShop...last image is what I wanted. I normally do vector work, not raster. Arrrgghhh. I hope that image helps some folks.
With two failures in such short time (miles) I guess Kawasaki had a design flaw (or their supplier did).
FWIW. HTH. YMMV. EIEIO.
