Not my experience with my '05 Triumph Speedmaster, bought new, still have. In 48+k miles, other than tires, chain/sprocket sets & 1 battery (going on 10 years for battery 2), the only unplanned problems have been an ignition module & the trigger pickup coil under the alternator cover. Admittedly it could use a clutch but it's still very usable.
No leaks, no Lucas electrical fiasoes, no wicked vibrations, no noticeable oil consumption & I've heard " damn, that's a good-lookin' ride, what year?" more times than I can ever keep track of. I've never even had the carbs off & apart except for rejetting about 11 years ago.
