The seller of this example calls it a ’50s period-correct hot rod that has set several 500cc Vintage Sidecar land speed records at Bonneville.
The main components include a WLA frame, WLA engine, Servicar transmission, and a K model front end (hydraulic instead of girder). It was originally built as a hunting bike in Montana – the Servicar transmission was installed so the owner could use reserve to tow elk out of the woods. “Starts, stops, runs and goes like one would expect a 1942 WLA to. Hopped up for some extra horsepower.”
