Harley math
Now, I'm not bagging on you for liking riding a Harley--if you like a bike, ride it. That's what it's all about, right?
BUT...
First, Japanese bikes are NOT simply disposable. Why does everyone say this? A well-maintained Honda lasts at least as long as a well-maintained Harley. Maybe some people choose to trade up because they like a new model or want to "keep up with the Jones's," but it's NOT because Japanese bikes up and die after five years.
Second, the "resale value" math that HD owners often cite is flawed. I've posted this a ton of times, but I'll do it again. Compare a $20,000 out-the-door HD and an $8000 Japanese bike (600cc supersport; ZRX; Concours; Shadow 1100). Rider A spends $20,000 on the HD; Rider B buys a Japanese bike and puts the remaining $12,000 in the bank (earning a VERY conservative 4% APR--but hey, the economy's down).
Ten years later, they both sell. Rider A gets $20,000 for his used HD. Rider B only gets $2500 for his bike, but his $12,000 in the bank has turned into $17,763. They're equally as good off economically.
Now, if you bump that 4% APR up to 8% APR (say, the economy is up and some of the money goes into the stock market), then after 10 years the $12,000 in the bank would be $25,907, and Rider B would be significantly better off economically than Rider A.
If you love your Harley, ride it every day. That's the best reason to have a motorcycle--because YOU enjoy being on it. But ride it because you love riding it, not because of flawed economic arguments or some myth of Japanese unreliability.
