Mid-Life Motorcycles (MLM) is a small shop that builds customized motorcycles, mostly for middle-aged men with significant discretionary income who are hoping to fulfill a high-school dream. Since it works with high-end clients, all of its work is custom and it makes many of the bike parts used, including frames, in-house. Other parts, such as the engine, are purchased from outside suppliers and then modified in-house. Although most of the bikes are built to-order for a specific individual, the shop occasionally builds a bike with no prearranged buyer. These bikes are sometimes intended to be entered in custom-bike contest and then sold afterwards.
