This stunning 1915 Harley-Davidson 11-K will be hitting the auction block in Monterey next month. The 11-K accounted for Harley-Davidson's first purpose-built track racer, with no brakes, no gears, no suspension, a highly tuned motor with open breather ports in the cylinders, and a flat-out racing Schebler carb. Back then, the bike retailed for a breezy $300 USD.

This particular 11-K was discovered in Argentina. Much of the frame was missing, and the piston and a rod were broken. Rebuilt, the bike now boasts an 11-K-specific 1.25-inch racing intake manifold, 1.25-inch exhaust ports, one-year-only ported cylinders, rocker towers, rockers with top and side oilers, braced racing forks with André dampers, and the original wheel hubs. The 3.5-gallon racing tank is a reproduction of the original factory item, just like the original bike's signature orange finish.
