Suzuki's masterstroke with the Gsxr 1000

Suzuki's masterstroke with the Gsxr 1000 was the implementation of a geardriven counterbalancer.
Long - stroke, largedisplacement inline - fours can have unacceptable levels of vibration, but the counterbalancer offered an opposing force that effectively eliminated the vibration.
From there, the benefits accrued, as the rest of the motorcycle could be lighter when not subjected to vibration.
