My leak was from a hose clamp, and the leak showed up in what looks like the same place (hard to tell though in the image), directly under the horn.Hello,
If you see coolant leaking from the underside of the radiator, the radiator cap is faulty.
I had the problem myself and I saw a second case on Facebook, so it's highly likely that others are also affected.
It happens when the bike is stationary, the engine is hot and the ignition is switched off. It sounds like a pressurised steam pot and suddenly there's a leak under the radiator.
