1.) All motorcycles are "top-heavy"! (Try parking one without the side or center stand extended...they fall over.)
2.) Yes, the FJR, like all sport touring bikes, is more top-heavy than some other styles of motorcycles (like cruisers).
3.) There are many vertically challenged and strength challenged FJR owners (because of gender, age, physical dimensions, etc.).
4.) Problems with dropping the motorcycle are not purely the bike, it is operator error or rider lack of proper technique/training.
Bounce has said it more succinctly...take an advanced rider course, then practice, practice, practice until the techniques and ability to foresee uneven ground become second nature.
I may be "normal-size" but I've ridden with enough of those mentioned above to recognize and celebrate their ability to overcome what some would see as a genetic shortcoming for riding this size of machine.
It can be done and it IS done by too many to blame the machine.
