Which of the following is NOT one of the six primary controls?

• A. Throttle
• B. Clutch Lever
• C. Headlight switch
• D. Gearshift Lever

Answer: (C)

Primary controls are the essential levers and switches you use to operate the bike’s movement and gears. They include throttle to control speed, the clutch lever to disengage the engine for shifting, the front brake lever and rear brake pedal to slow or stop, the gearshift lever to change gears, and the engine stop/ignition switch as part of the core controls. The headlight switch is a lighting control for visibility, not something you use to move or change gears, so it isn’t counted among the six primary controls. That’s why the headlight switch isn’t the correct option. Throttle, clutch, and gearshift are clearly primary controls because they directly affect acceleration, gear selection, and power transfer.
