I run a 2010 Honda Goldwing and there's that warm antifreeze smell after every ride, though I've yet to see any actual pooling. Is this a known issue with the pressure system not venting right or are there common heat related seal failures?
 
I've experienced something similar with my '08 as well, there was a warm antifreeze smell, but no puddles to be found. It turned out to be a small leak from a hose clamp close to the thermostat housing. This issue is pretty typical since those clamps can become loose over time with heat cycles. Take a look at all the coolant lines and clamp connections, especially the ones up top. If your coolant level is stable and there's no overheating, it's probably just a little evaporation happening from a hot surface.
 
That warm antifreeze smell on Goldwings is practically a design flaw Honda never fully owned up to. Riders chalk it up to normal, but low-key, it's often a weeping seal or cap issue they underbuilt
 
@WingedTraveler thanks for the tip about the hose clamp. I took some time this past weekend to inspect all the connections in that area as you suggested. You were right, 1 of the upper clamps was a little loose with some white residue around it. I tightened it up and the smell has now gone away.
@comet that's an interesting take on the issue and it would explain why so many owners report the same smell. After checking my bike based on @WingedTraveler's advice, I found a loose hose clamp was my specific problem, not a failing seal this time. It does make 1 wonder why these particular clamps tend to loosen over the years.
