Why is it called a bobber?
A bobber is a style of custom motorcycle that has undergone a “bob-job”, which involves removing extraneous parts for simplicity and weight reduction. The term “bobber” originated from this practice.
Defining Characteristics:
A bobber motorcycle typically features:
• Removal of the front fender
• Shortening of the rear fender
Origins & Evolution
• The bob-job evolved from an earlier type of American custom motorcycle known as the “Cut Down.”
• Cut-down motorcycles appeared in the late 1920s and were based on the Harley-Davidson ‘J’ series v- twin.
• To modernize the appearance and improve performance, cut-downs involved removing the front fender, shortening the rear, and eliminating excess accessories.
• The modified frame resulted in a lower, shorter machine with a sweeping diagonal line between the steering head and rear axle.
• In 1933, the American Motorcyclist Association (AMA) introduced Class C racing, inspiring the creation of bob-jobs.
• Class C racers like the Indian Daytona Scout and Harley-Davidson WLDR and WR served as the inspiration for these stripped-down road bikes.
• Road riders adopted the racers’ look for better performance and style.
• The first bob-jobs emerged in the mid-1930s, characterized by plain paint jobs and no extra chrome or decoration.
• After World War II, bob-jobs became increasingly decorative, with features like extra chrome plating, metal flake paint, and pin striping.
• Customizers like Kenneth Howard (“Von Dutch”) added wild paint jobs, smaller gas tanks, raised handlebars, and unique exhaust pipes.
• Bob-jobs grew in popularity, both as show bikes and everyday road bikes.
• Motorcycle manufacturers, including Harley-Davidson and Honda, were influenced by this style.
• Commercially produced road-going bob-jobs only became available in the late 1990s.
What’s the difference between a bobber and a chopper?
Bobbers
Definition: Bobber motorcycles usually consist of a stripped stock motorcycle, shortened fender, and other essential parts and accessories that can be seen in other motorcycles.
Frame and Geometry: One key difference is that bobbers retain the original factory bike frame. They maintain the frame and fork geometry for proper handling and top speed.
Appearance: Bobbers are characterized by a more minimalistic and lightweight design compared to choppers.
Chrome and Styling: Bobbers typically have less chrome and focus on practicality and performance.
Purpose: They are built for speed and handling, making them suitable for cruising around town or covering shorter distances.
Choppers
Definition: Chopper motorcycles are made up of a modified form of the original factory frame.
Frame Modification: In choppers, the engine and transmission are eliminated, and the factory frame is cut and welded back together to create a lower and lighter appearance.
Styling: Choppers are highly stylized and often feature shiny chrome detailing, a 45-degree angle front fork, and other exciting custom features.
Long Distances: They are built to cover long distances with specific accessories and parts. Customization: Choppers allow for more extensive frame modifications, resulting in unique and eye- catching designs.
In summary, while both bobbers and choppers are custom motorcycles, bobbers prioritize
performance and practicality, while choppers are built for flashy style and visibility. Next time you spot one on the road, you’ll know whether it’s a bobber or a chopper!
