Ha - I've done the same thing. The only thing holding the seat onto the bike is my ass, and it hasn't gone anywhere yet. And your assessment of "if it goes flying off when I'm going down the road..." is my sentiments exactly!I don't fasten my seat to the bike anymore. If it goes flying off when I'm going down the road, I have other, more pressing issues that will make losing the seat seem minor. The bike has been around the block a few times. The seat has never come up to meet me on my way down.
Same here.. With my Pelican top box and the shape of my Russell seat, you have to wiggle it just right to get it out.. Even harder to do when I'm sitting on it..Just removed the seat bolts and left it like that..the seat never moves, just wedges in by the rack and stays there.
Yes; and . . . fuses!
One of the other reasons is that if you have saddlebags mounted to the bike, the frames for the bags can make it a pain to remove the side covers. The covers can't pull out unless you take the saddle bag frames off.. (depends on saddlebag frame design)
