You are going to get slaughtered with depreciation.
Not if i buy used bikes.
Sure you will, just not as badly. You're buying when everyone else wants to buy, and you're selling when there's no market for them. It's near impossible to sell a motorcycle in this market from about August through February unless you blow it out cheaply. And no matter how you slice it, you are paying the tax on the purchase and you can't recover that when you sell.
If your tastes run to older bikes, frequently the depreciation curve levels off after 7 or 8 years ... as long as you don't put so much mileage on them that no one wants to touch them. People in this market seem to think 20,000 km is high mileage ... I've done more than that in a year ...
