Over the years I have almost always had more than one motorcycle at a time, but never really had a collection. Collecting stuff has a lot in common with activities like recreational drug use or gambling, it can be fun, but watch you don't get hooked. In my case the wake up call arrives when I can't get into the garage anymore, and then it's 'everything must go!' until the garage is empty. After which, like coat hangers in a closet, a bike creeps into a corner, and another and another.
The collecting bug does not discriminate, people collect all kinds of shit, from buttons to military tanks.
I never saw my random moto acquisition binges as an investment, I was mostly sucked into buying old bangers through the motorcycle price-age curve, a tool used by economists to study the demand for rusty old crap.
As you can see in the graph below, the actual selling price of a motorcycle descends very swiftly the moment it leaves the showroom, mostly because the dealership lied about how much it was REALLY going to cost, vs 'manufacturer's suggested list price' such as taxes, shipping, dealer fees, and all the usual (useless) shit they managed to upsell before the buyer exits the building sadder, wiser, with empty pockets, drained bank account, and 7 years of payments.
