1988 BMW R100GS Bumblebee

The R100GS is the OG adventure bike that started it all—and this '88 Bumblebee is a low-mileage, all-original survivor with fresh internals and just the right touches (Ohlins, Corbin). At $11,500, you're getting the bike that made BMW legend before the market caught on to what it was worth, plus you actually *want* to ride it instead of museum-piece it.
