Bought HD extended warranty on:
- my '06 Ultra (purchased in '05) - recouped over 10 times what I paid for the warranty - mostly from flywheel/connecting rods failure at 75k miles that required an engine rebuild. Various other issues over the years including a stator and voltage regulator on the road in SD. Sold the bike in '13 with 130K on it when the warranty ran out and couldn't renew it because of the mileage on the bike.
- my wife's '04 Fatboy - with wheel & tire coverage, recouped 2 times of cost. Had both tires pick up nails thru a construction zone - a month later, another nail in the new rear tire - the covered tires alone were nearly half the cost of the warranty. Also covered an engine rebuild when a cam bearing failed at 85k. Bike currently has 108,000 on it. No warranty anymore - max warranty is 12 years.
- my current '11 Limited - bought bike used in '13 with 10k on it and had HD ext warranty with wheel & tire transferred. Now has 60k. So far - not much done by warranty, but nice to have when they tell me the rocker boxes are leaking - $50 is my cost to repair; or they find a nail in the tire (zero deductible on wheel & tire). I will be renewing for the additional 5 years allowed.
The thing to remember - it's called an extended warranty - what it really is, is an insurance policy covering repairs. Like almost any other insurance, it's risk management and can provide peace of mind knowing your exposure is limited. Each person has a different tolerance for risk.
Also a huge factor in this specific market is how much you ride, how you ride and how long you keep a bike. Someone like Harttoo (see post #4) who trades off frequently, maybe not so much value in an extended warranty because he doesn't keep the bike for an extended period of time. Someone like me - I keep my bike a long time and put a lot of miles on (relatively speaking) - increases the risk, so to me an extended warranty has value.
Finally - the HD extended warranty can be transferred with the sale of the bike, when sold to a private party (i.e. not when traded to a dealer). A tool to facilitate the sale, maybe.
JMHO - FWIW
edit - wow, sorry for the length...
