well if you look at how warfare is done today, i dont see how motorcycles would be of any use, because now battles happen 200-1000 feet away with rifles, and there is never hand to hand combat so riding a motorcycle into the battle would just be suicide. the only sensible place where motorcycles would make sense is in guerilla warfare, like hit and runs or assassinations. an example from sikh history would be like harjinder singh jinda and sukhdev singh ji sukha, where they assassinated the enemies of the khalsa panth such as lalit makhan and general arun vadiya. jinda sukha assassinated them both on a motorcycle.
