I got to thinking today about how our bikes, and motorcycles in general, lose value over time. In the case of bike ridden about 8,000 or more miles per year is there any validity in thinking in terms of $ per mile for depreciation? I rode my Goldwing 52,000 miles and 8 years and sold it for roughly $5000 to $6000 less than I paid for it. That was a depreciation of about 10 cents/mile. I paid $15,000 for my 2013 base Spyder RT, including shipping, and have ridden it 20,500 miles since spring, 2014. I'm thinking it's probably worth something on the order of $13,000 now, or roughly $2000 less than I paid. Again, that's a loss of around 10 cents per mile.

Low mileage bikes, like with 2000 miles/year, would have a much higher $/mile drop simply because age would the primary determinate of price.

Just wondering if $/mile might help us get a better idea of how much our Spyders drop in value. Your thoughts?
