Coolant Consumption 2012 NC700X 46K miles....

I bought this bike from the original owner in 2019 @ 33K miles. At some point around 35K miles? I noticed the reservoir was low and I filled it up. Last time I checked it was 2 years ago when I had to replace a damaged radiator hose at that time the reservoir was low @39K miles. This time the reservoir was empty and the radiator was low about 1 inch from the top. I added a total of about 12 oz of coolant between the radiator and reservoir.

Anyone else experience any coolant consumption?

Have not experienced this issue on this model. On a former KTM a similar issue occurred which was caused by a faulty rad cap return valve. Is there any sign of coolant overflow from the reservoir ?

My '12 (mine since new) lost coolant very slowly some years back. It never lost quickly, and I never found any evidence of coolant in oil analysis. Nevertheless, I eventually replaced the radiator cap. That fixed it.

Something similar happened with mine and was one of the hose clamps that was loose, just got it tighter and problem solved.
