The position of the speedometer on motorcycles can vary based on design choices made by manufacturers. There are a few reasons why some motorcycle speedometers may not be centered or positioned on the left or right side:
Aesthetic Design: Motorcycle manufacturers often prioritize the overall aesthetic appeal and design of a particular model. Placing the speedometer off-center or on the left or right side can create a unique and visually interesting look.
Ergonomics: The positioning of the speedometer can also be influenced by ergonomic considerations. Placing the speedometer on the side can provide better visibility and readability for the rider without having to take their eyes off the road completely.
Handlebar Configuration: The position of the speedometer can also be influenced by the handlebar configuration. Some motorcycles, like the Ducati Scrambler or Yamaha MT-09, may have wider handlebars or a specific design that limits the space available for a centrally positioned speedometer. In such cases, the speedometer is placed on the side to accommodate other components and maintain a balanced design.
Customization Options: Motorcycle manufacturers often provide customization options for riders, including aftermarket accessories or modifications. Placing the speedometer on the side can create more flexibility for riders to customize their bikes with different handlebars or fairings without affecting the central position of the speedometer.
Ultimately, the position of the speedometer on a motorcycle is a design choice made by the manufacturer, taking into account various factors such as aesthetics, ergonomics, and practical considerations.
