Why does the rear wheel of a motorcycle tend to lock when braking rather than the front wheel?

When braking on a motorcycle, the weight of the rider and bike shifts forward due to inertia. This forward weight transfer reduces the load on the rear wheel, making it less stable and more prone to locking. The front wheel, however, gains more load and has better traction. This is why the rear wheel tends to lock first during braking. Understanding this helps riders use braking techniques effectively to maintain control.
