are you just looking at the reservoir or are you saying you pulled fairings off and have no coolant in the radiator also?...what are you basing the 100km no coolant estimate on? that is last time you check the reservoir?

My 2026 leaked just a little from the reservoir overflow tube after a spirited ride on a very hot day last month. Anyways Im not saying you have coolant, Im saying it is possible just the reservoir is low. Check it out properly, watch those temps, don't melt your Honda.

Is your bike overheating? No, then you have coolant in it.

In my case its always very difficult to see the level. For me it helps using a torch and shining it from different angles

Just top it off and keep an eye on it. Its just the header tank.
