Clutchless Shifting

Just to share something that I tried when racing the Scrambler today. It was clutchless shifting.

Initially I thought it would be efficient as it doesn't require pulling in of clutch thus no power loss occurs during the shift. But then I realised it was wrong. Clutchless shifting allows the time-possession by not pulling the clutch, but it wastes power due to the technique used.

Clutchless shifting is done when the engine is revved up high, and closing in the throttle in a split second to allow the rpm to drop and kick in the gear. But by dropping the throttle, engine-brake occurs, deceleration happens. Plus shifting by disengaging the clutch allows the rider to maintain the engine revolution, while shifting the gears, and putting the wheels back into transmission at the power band.

Plus, experienced riders can change gear by disengaging clutch fast enough not to incur time-loss.
