California DMV Motorcycle Knowledge Test (M1)Motorcycle Controls and Basic ManeuversMedium
A rider is descending a steep decline and wants to use engine braking to assist in controlling speed and reduce wear on the friction brakes. What is the correct technique for effective engine braking?
- APull in the clutch lever completely and coast.
- BApply constant, light pressure on both friction brakes.
- CDownshift to a lower gear, allowing the engine to slow the motorcycle.
- DShift into a higher gear to reduce engine RPM.
Show answer & explanationAnswer & explanation
Correct answer: C. Downshift to a lower gear, allowing the engine to slow the motorcycle.
Engine braking is achieved by selecting a lower gear, which causes the engine's internal resistance to slow the motorcycle. This reduces the reliance on friction brakes, preventing them from overheating, especially on long descents. The lower the gear, the greater the engine braking effect.
Why the other options are wrong
- A. Pulling in the clutch disengages the engine from the drive wheel, eliminating engine braking entirely and allowing the motorcycle to coast.
- B. While constant light pressure on friction brakes is a braking technique, it is not engine braking and can lead to brake fade on steep descents.
- D. Shifting to a higher gear would decrease engine RPM and reduce engine braking, causing the motorcycle to speed up.
Engine Braking
Using the engine's resistance to slow a motorcycle by selecting a lower gear, reducing reliance on friction brakes.
- Achieved by downshifting.
- More effective in lower gears.
- Helps control speed on descents.
- Reduces wear and overheating of friction brakes.
Memory trick: Downshift low, let the engine slow.
