1947 Harley-Davidson UL Bobber

The need for speed is an age-old quest. ‘Blue Mule’ is a surviving example of a late 1940s ‘bob-job’ speed-machine. Now referred to as bobbers, bob-jobs evolved from ‘cut downs’ —the race-modified Harley-Davidson J Series motorcycles of the late 1920s. Along with the J Model, the stripped-down AMA Class C racing motorcycles of the mid-1930s also served to solidify the style of post-WW2 bobbers.
