____________ helps make your downshifting smoother.

Rolling on the throttle while downshifting is essential for achieving smoother transitions between gears. This technique allows the engine RPMs to rise appropriately as you shift to a lower gear, matching the engine speed with the speed of the motorcycle's wheels. When you roll on the throttle during downshifting, it decreases the likelihood of engine stalling or causing the rear wheel to skid, which can happen if the engine speed is too low compared to the rear wheel speed.

By maintaining throttle control, the change in gear becomes more gradual, leading to better stability and control of the motorcycle. This is crucial for safe riding, especially in situations where maintaining traction is important, such as cornering or navigating slippery surfaces. The other choices may not facilitate this smooth operation effectively, emphasizing the importance of throttle application while downshifting.
