To answer the question, there is no difference between the motorcycle side package and the bracket, in this case, the motorcycle side package with the bracket is basically a side bag made of ordinary leather. It's a little harder to take off because it's attached to the bracket. What's missing is hard, thick leather. It can be removed without fixing.
There is also a fixed bracket for the side bag installed on the motorcycle, there is no fixed bracket, only the suspended bracket, the installed side bag is very stable, high safety performance, strong carrying capacity, but the side bag without a bracket, the fixed force deviation is weak and easy to fall off. I hope my answer can help you.
There is a bracket, can support the motorcycle is more stable, no support is not supported, received the external wind effect, will blow the motorcycle over, will cause damage to the motorcycle!
