Viking Bags Dyna Sissy Bars 101 Guide

1. What is a Dyna Sissy Bar?

A Dyna sissy bar is a narrow inverted V-shaped metallic bar typically fixed behind the passenger seat at the rear of specifically Harley-Davidson Dyna models. Its primary function is to extend the length of your motorcycle, providing additional places to carry your motorcycle luggage, and increasing your vehicle’s storage capacity. It is useful for carrying sissy bar bags, roll bags, and other baggage too large to be secured anywhere else on your vehicle. However, it can also serve as a backrest for a motorcycle passenger thanks to built-in padding or the attached motorcycle luggage providing a cushion. Aside from its practical functions, a Dyna sissy bar can complement your motorcycle’s appearance by providing both a stylish and clean look.


While a Dyna sissy bar is not required for your motorcycle to function at optimal capacity, its utility makes it a useful piece of equipment to have if you are carrying an additional person or going on a long motorcycle trip. If you are interested in purchasing a Dyna sissy bar, this guide will give you a detailed overview of what Viking Bags has in stock.

2. Types of Dyna Sissy Bars

Dyna sissy bars are designed to be mounted on only Harley-Davidson Dyna models such as Dyna Low Rider FXDL, Dyna Super Glide FXD, Dyna Street Bob FXDB, Dyna Fat Bob FXDF , and Dyna Switchback.


All Dyna sissy bars are constructed from thick round bar steel which helps ensure the equipment is weather-resistant, rustproof, and long-lasting.


Dyna sissy bars are designed to be aerodynamic to prevent drag and ensure the optimal performance of your motorcycle when riding at high speeds. They are also tested for the maximum weight they can carry without straining your motorcycle’s suspension system.


While every Dyna sissy bar uses high-grade steel construction as a base, they differ in their design based on the type of finish applied. They can either come in stainless chrome or matte black paint. Both provide a protective surface that protects Dyna sissy bars from debris, rainfall, etc.


Most Dyna sissy bars are designed with a tipped tip that is bent at an angle to help catch onto your motorcycle luggage and keep it from coming loose when you are riding at high speed.
