The cost of an old motorcycle usually depends on a few things — the rarity of the motorcycle, condition of the motorcycle and the age of the motorcycle.
Age and rarity goes along to drive up the cost. The older the motorcycle, the more expensive it is (when it is above 35 years old). Generally, the price of a motorcycle goes up around 50% every 5 years (depending on bike type, rarity, etc)
So it can be a good investment to own and maintain a classic motorcycle. In terms of condition, a restored motorcycle can cost a lot more than a “project bike”. However, if you really love that motorcycle and would like to own it and do it up yourself, getting a project bike is a good way to learn more about the bike.
Recently I’ve been working on a BMW K100RS. The K100RS, also known as the flying brick is a reliable workhorse. At 987cc, it is fast enough to keep up with the modern vehicles on the highway, and have enough braking power to be using the motorcycle as a touring bike.
