When should a motorcycle rider use BOTH front and rear brakes simultaneously?

BOTH BRAKES TOGETHER is the MSF standard for all braking situations. The front brake is the more powerful of the two — physics dictates that weight transfers forward under braking, loading the front tire and giving it more traction. The rear brake alone uses only the lighter, less-loaded rear tire. Using both: maximises total braking force; distributes heat between both brakes; allows earlier, more controlled stops. FRONT BRAKE TECHNIQUE: Apply progressively — not a sudden grab that can cause front wheel lockup; squeeze, don't jerk.
