For the engine to turn when the starter was pressed, the transmission had to be in neutral. And if you forgot to shift into neutral before parking the Honda CB750A, deploying the side stand would do it for you. Both of these features were obviously intended to prevent unintended launches. Similarly, a push-button parking brake acting on the rear wheel prevented the bike from rolling away if parked on a slope, there being no direct gear linkage between engine and wheels. Even after the brake button was released, the brake remained on and the bike wouldn’t roll until the rider dabbed the brake pedal.
