you ask if they bit off more than they could chew but it sounds like they never learned HOW to chew.
I swore them off for good back around 2003 after the final straw when they dropped my Triumph during service - cracked the fairing, scraped bar ends/center fairing and scuffed the gearbox then took MONTHS to even replace the one fairing.. it ended up being a daily ritual of harassment until finally one day they came through.... and all this is after one servicing where they forgot to put anything in my radiator and a few other random bonehead manuevers which clearly demonstrated they dont even bother to test ride after performing maintenance.
crazy to hear that even today they're still making the same kind of piss poor mistakes.
at first I wrote it off to just bad help in the service dept.. but after the fiasco with the fairing, I'm pretty sure the problem is cutting corners at the top.
