First of all, determine where the leak came from. It's most likely one of two things:
If it's the first, you can simply repair/replace the hose.
If 2, then there is either an airbubble or some other blockage preventing the flow of coolant. I am assuming you did not see a fast rise in engine temp just before this, and you say you've been riding a while, so it probably isn't the second option.
This should be a lesson for you and all riders: do NOT ignore odd sounds on a motorcycle (one good reason not to listen to music etc when riding). That sound you heard, like a small cracker fizzling, was probably the coolant boiling away as it sprayed on the hot exhaust. While this may have been caused by a Quality Assurance problem at the factory, it was still your responsibility to be aware of what was happening and not ignore an odd sound your bike was making.
As expensive as this bike is, comparatively, you should want to catch any malfunctions before they escalate into major problems. This isn't some piddly little Splendour or Discover that you can ride into the ground and push into the weeds when it dies. As you note, this could have stranded you far from help had you been on a longer ride, but you should also consider the following possibility: what if the leak had been more sudden, as in dumping all the coolant immediately, and had hit just as you were going into a high-speed curve in traffic? Coolant is notoriously slimy, and you would have instantly lost all traction, and maybe gone under the wheels of a truck.
As I noted in an earlier post, malfunctions on a bike have a much greater chance to render the bike unrideable, and not just in a coast-to-the-curb sense. They can literally render the bike instantly inoperable, even at highway speed. You HAVE to stay on top of what the machine is doing.
To provide an example, I used to own a 1990 Kawasaki ZX-11. Big bike, and very fast. I rode it halfway across the US in two days. During that trip, at one point I stopped to rest and get something to eat and some fuel, and noted a faint hissing noise coming from under the seat. I opened it up, and discovered that the battery had boiled itself nearly dry. Early ZX-11s (apparently) had a notoriously-bad voltage rectifier, and would overcharge the battery when the bike was ridden for long periods at higher speed (I was averaging 135km/h, and had been riding for a good 6 hours straight by then). Had I ignored it, the battery very likely would have exploded right underneath my crotch while doing 135 on the highway, and I might very well have panicked and/or wrecked, and killed myself in the process.
Because I discovered the problem in time, I was able to buy some distilled water, top off the battery and put a couple liters in my luggage for later. I had to top the battery off at least 3 more times on that trip, and several times after that. It was a design flaw in the bike that Kawasaki fixed in later generations, but wasn't considered bad enough to result in a recall. It's a known issue with the early bikes, and as long as you are aware of it, it's a matter of a couple extra minutes during that daily walkaround check to look at the battery, and just something you have to know to check on longer rides.
- A hose has either come loose or has split
- All the coolant has been pushed out of the overflow tank

That was a close shave
