It's all about balance, IMO. HD bids some parts out to the lowest bidder that supposedly can build the item to their specifications. The corporate attitude at HD seems to be more concerned with stock prices than with overall customer satisfaction. That comes from the top down. When they came out with the 110 in '07, there was absolutely NO EXCUSE for the problems that many, many people had with those engines leaking oil from the cylinder bases, rockers hitting the covers, and the several other problems buyers had. No excuse. If they had taken 10 pre-production bikes and actually ridden them between 5-10K miles, 5 of them would have developed oil leaks. Recent problems with lifter failures are another example of inadequate long term testing, inferior (likely low bid) component material, etc. IMO, what HD depends on are buyers who ride very little...how many Harley's do you see advertised that have 5K miles on them and are 5 years old? Quite a few. Those people are not riders...they are toy buyers, bar hoppers, or weekend warriors. Certainly, no new product is going to be 100% and not need a few tweaks here and there, but if you are producing a motorcycle that costs as much as a very, very nice cage, is intended for long distance riding, and is supposed to represent the very best of the best in your product line, to have some of the types of problems they have is simply inexcusable. The occasional electronic glitch, a bad batch of bearings, the bad tire here and there, etc is one thing, but crankshafts that are so far out of true that they start taking out other engine parts, lifters that fail and eat the rest of the engine after only 25,000 miles or so, stereo systems that do not function properly...that is NOT rocket science, and the incidence of those types of problems should be practically non-existent. Nobody here would put up with a new car/truck that had some of these types of problems, and rightfully so. There will always be the occasional "lemon" that comes off the line for whatever reason, but they should be very far and few between on a two wheeled product costing nearly $40,000.
It's like the old skit on Laugh In where Lily Tomlin played the phone company operator and her standard line for a customer reporting a problem was "We don't care...we don't have to". If HD was more concerned with building reliable bikes and less concerned with how much they are going to pay their CEO, how much the stock options are going to be worth, and what kind of earnings their stockholders are going to receive in any given year, and instead focused more on customer satisfaction, admitting to problems without the "they all do that" attitude, the money would follow, regardless. Maybe not as MUCH money, but gracious plenty for all but the most greedy.
American car companies learned that lesson the hard way when they kept producing the same old chit with different paint jobs or cosmetic changes...the Japanese took over the market, and justifiably so. Brand loyalty will only carry an inferior product for as long as there are old customers who will buy the chit regardless of quality...once those folks quit riding or die of old age, the company will find itself in a world of chit, playing catch up.
