California DMV Motorcycle Knowledge Test (M1)Motorcycle Controls and Basic ManeuversMedium
A rider is experiencing difficulty with their motorcycle repeatedly stalling when coming to a stop. What is the most likely cause of this issue?
- AIncorrect tire pressure.
- BExcessive throttle application during deceleration.
- CReleasing the clutch too quickly or not pulling it in fully.
- DInsufficient front brake application.
Show answer & explanationAnswer & explanation
Correct answer: C. Releasing the clutch too quickly or not pulling it in fully.
Stalling when coming to a stop is typically caused by the engine being loaded by the transmission when it shouldn't be. This happens if the clutch is released too quickly (engine speed drops below idle) or not pulled in fully (clutch still partially engaged).
Why the other options are wrong
- A. Incorrect tire pressure affects handling and stability but does not directly cause the engine to stall when stopping.
- B. Excessive throttle during deceleration would prevent stalling, not cause it.
- D. Brake application affects slowing, not typically engine stalling unless it's an emergency stop causing a rapid engine load.
Stalling on Stop
The engine shutting off unexpectedly when a motorcycle comes to a stop, usually due to incorrect clutch operation.
- Caused by clutch issues.
- Engine speed drops below idle.
- Prevented by proper clutch disengagement.
Memory trick: Clutch control prevents the stall call.
