Absolutely, motorcycles are by their very nature inherently unstable. It seems to me that the manufactures problem is finding the balance between stability and handling. A long wheelbase and raked out fork will give a more stable motorcycle but it won't be spritely around the corners, give it a short wheelbase and a steep fork and it'll want to fall over! I bought a new Fireblade in '93 and nearly fell off at my first roundabout, I put it into the roundabout and it went over so quickly I nearly got caught out.Wow an honest and fair minded thought !!!! Watch MotoGP they (with all their engineers and money still get a weave) not all the time but a condition happens to cause it. Think about it, take a gyroscope and spin it, sometimes its good but it just takes the smallest thing to throw it off and it wobbles. On a bike you have two gyroscopes. Just because you have not experienced the weave before doesn't mean you have hit the condition the can cause a weave.
I suspect those MotoGP bikes are so quick to steer that they are incredibly unstable, put a bit of weight high up (top box) and I bet they would be all over the place!
But that instability is what makes motorcycles such fun to ride. I don't believe that the Pan is a dangerous motorcycle unless you do something silly, the same could be said of any vehicle two wheels or four.
