The balancer device is composed of a special crankshaft that activates
2 additional shafts (balancers).
Rotation of the balancers, which have counterweights that oppose the
movement of alternating weights (crankshaft - connecting rods -
pistons), reduces vibrations caused by them.
The device is developed under the crankshaft, fixed on the crankcase,
closed by the oil sump.
