California DMV Motorcycle Knowledge Test (M1)Motorcycle Controls and Basic ManeuversMedium
A rider is preparing to shift from first to second gear on a manual transmission motorcycle. After accelerating in first gear, what is the next correct action to ensure a smooth upshift?
- APull the clutch in, then momentarily roll off the throttle.
- BShift up, then pull the clutch in while maintaining throttle.
- CRoll off the throttle, pull the clutch in, then shift up.
- DRelease the throttle completely, then pull the clutch in.
Show answer & explanationAnswer & explanation
Correct answer: C. Roll off the throttle, pull the clutch in, then shift up.
To achieve a smooth upshift, the sequence is to roll off the throttle slightly to unload the transmission, then pull the clutch in, shift up, and finally release the clutch while rolling the throttle back on.
Why the other options are wrong
- A. Pulling the clutch in before rolling off the throttle could cause the engine to over-rev if not done precisely, or lead to a 'power shift' which can be hard on the transmission.
- B. Shifting up without pulling the clutch first (unless power shifting, which is not for beginners) can damage the transmission.
- D. Releasing the throttle completely before pulling the clutch can cause a sudden deceleration, making the shift jerky.
Upshifting
The process of changing to a higher gear on a manual transmission motorcycle, typically done as speed increases, to maintain engine efficiency and smooth power delivery.
- Requires coordination of throttle, clutch, and shifter.
- Aims to keep engine RPMs within an optimal range.
- Smoothness prevents loss of traction or control.
Memory trick: Throttle off, Clutch in, Shift up, Clutch out, Throttle on.
