Vince hit the nail on the head.
Riding with a couple of fingers resting (not pulling) on the clutch lever will dampen out all vibration and allow the rider to instantly disengage the clutch if an emergency like a panic stop or a blown out inner tube happens.
While doing this, also keep a few fingers lightly resting on the front brake lever (use your thumb and forefinger to grip the throttle. It works great.).
Riding with a few fingers on the front brake lever dampens out vibration on the brake lever and in the event of an emergency, reduces the time needed to apply the front brake and stop the motorcycle.
It can easily take over 1/2 second to move your fingers from the handgrip to a position that can grab the brake lever and begin to apply the brake.
At 60 mph (97 kmph), the bike will cover a distance of 44 feet (13.42 meters) in that 1/2 second.
At just 30 mph (48.4 kmph), the bike will cover a distance of 22 feet (6.71 meters) in that half second.
That's over 7 yards of distance traveled just during the time it takes to get your fingers on the brake lever.
I'd much rather stop 1 yard short of hitting something than 6 yards after hitting it.
