Mounted with the Vmc Siluro Sport the cylinder transforms into a fast touring engine with generous torque even at low revs and excellent acceleration.
Attention: To be mounted on Piaggio crankcases it is necessary to eliminate the crescent on the crankcase base and bore the cylinder mouth on the crankcase with a diameter of 64mm for a depth of approximately 8mm to allow the cylinder liner to enter the crankcase.
