— $29,500 OBO —

HISTORY: This 1949 Harley Davidson WL has a great history and it is a very rare edition of the 45ci flathead. This exceptional motorcycle is listed in the Harley Davidson literature as a Specialty Model for the year because of the Aluminum heads and the use of polished Stainless Steel in the trim .

It was purchased on 3/25/51 from Billy’s Harley Davidson in Connell, Washington a wheat farmer named W.C. Dettman for his son. The son passed away unexpectedly in 1955 and the bike went into the barn.

The current owner saw an ad for a liquidation of the barn in 1988 and he noticed this WL and picked it up. This was the beginning of the Yanke Motor Museum in Boise, Idaho.

The current owner maintained the bike and rode it often well into the 90’s. This is an all- original paint, original to the 1949 Harley WL in Peacock Blue. This bike is complete with most of the original first-year items listed for this bike including the use of polished Stainless steel fender light, Air Cleaner, timer cover, and generator end cap.

OVERVIEW: Following the Harley-Davidson R Model, the 45 cubic inch WL made a long successful run as a universal motorcycle starting in 1937. The WL was replaced by Harley-Davidson K Model in 1952, and the middle-weight side-valve Harley-Davidson continued.

While using a slightly lower tech design than the 61 cubic inch OHV EL, the “flathead” 45 was the backbone of Harley’s lineup. Not only did it serve well as a courier machine with tens of thousands manufactured for World War II mostly in military specs, but also in numerous two and three-wheeled versions. And it was the mount of choice for many police departments. The WL series enjoyed great commercial success and was the basis of a machine for 750cc, 45 cubic inch Class C racing series which AMA launched in 1934; the Harley-Davidson WR.

For comparison, the WL is the basic model, with the sportier WLD, which used a higher compression ratio, referred to as the Special Sport Solo. Wheel sizes, styling and trim were nearly identical to the “big twin” EL and later FL, but the scaled down WL’s have a shorter wheelbase and less weight which offered more nimble handling.
