Welcome to the forum.
I would say it was a combination of driver error and a weak point. Most machines would break an axle when a wheel under power leaves the ground, and then hits the ground still under power. Got to get out of the throttle when wheels come off the ground.
With the stout axles Kawasaki uses on the KRX, it appears the axle is stronger than the driveshaft. I have read about a few people who have broken the driveshaft at that same location. Don't know if they all had the front diff. locked when it happened. That's a question I will have to ask when I see reports about the driveshaft breaking again.
