2017 versys 650 LT. My 1st bike so not savvy from maintenance prospective. The below caught my eye today as it is half full. What is this?

check and see if your bike is still under warranty-there are a few things that can cause that but none of them is good

It's supposed to look like coolant, usually green translucent, and not milky at all. It's mainly caused by dried coolant residue... You can view it better with right side cowling removed. What mileage are you at?

I'd definitely drain all coolant from your cooling system asap, refill with distilled water, run engine for 15 seconds, drain again and rinse out the reservoir and radiator pressure cap as well, then refill with some quality long life coolant for Japanese applications.

Bike only has 2,600 miles on it. Have extended warranty until 2023. I'll need to take it in for dealer for a check seems like.

The dealer will likely say it's normal, and that all maintenance such as replacing coolant is for you to do, or pay them to do it... I still recommend replacing your coolant now. It's probably just from dried coolant residue which collects in your breathing expansion tank (reservoir). The original coolant may be of poor quality, and it also collects paint, aluminum, oil, etc residues left behind upon initial engine assembly.

You are asking a lot from 1st time bike owner lol. Just kidding, really appreciate your feedback and help. I'll work on that as soon as time permits. I'll also check the coolant in the radiator to make sure it looks ok. I'm sure it is. Bike has not been heating at all.

Just swing by your dealer and have them take a quick gander at it. If they agree the coolant is milky, by rights they should change it and investigate possible causes under warranty. Even though coolant change isn't normally a warranty item, it should be in your case because milky coolant on a 2017 with under 3K miles IS abnormal and may indicate a different issue that WOULD be under warranty, unless the dealer put in some super-crappy or old coolant. And if the dealer won't play nice, I'd contact the regional factory rep to discuss it. Keep us posted.

I changed the coolant for the first time on my 2010 bike this winter. I just used a bottle of premix store brand. About the only thing I found doing this is that the new coolant is clearer, and perhaps slightly thinner viscosity wise. I don't see any reason to change coolant annually under normal circumstances. Most automotive coolant states it is good for 3 years on the jug. Some long life coolants state they are good for a longer period of time.

As others have stated. Coolant should never foam ever should be a clear pale green. If it is milky from gas or oil infiltration it means a defective head gasket usually.

Don't want to be a Debbie downer-but it looks like oil and water foam-hope it's something simple like a water pump seal

I'm back guys!

Took it over to the dealer in Shakopee, MN. Great service. They looked it over and found nothing alarming. No leaks anywhere to be seen and engine oil looks perfect. They are confident there is no leaking happening into the radiator so not really sure the reason behind the coolant turning milky in the reserve tank.

The good part is that they flushed it all out and filled it up with new coolant and all done for FREE under warranty :).

They will be filling a report with Kawasaki so this incident is documented in case of issue reappearing in the next few months. Good!. So, in the end, nothing major discovered and we will be watching how the coolant does in the next few months to a year.

To celebrate the not so bad news. I took her for an hour spin before heading back to work. She runs like a champ. LOVE IT.
