Soft/Original SHA66: Almost identical to the original Piaggio silent rubbers installed at the factory at that time (the silent rubbers sold by Piaggio today are much harder than back then with 72SHA). Very comfortable, greatly reduces engine vibration. Our recommendation for the everyday rider.
Color marking: 2 x red

Medium/Touring SHA66/82: Slightly firmer than the original Piaggio silent rubbers. Thus significantly better driving characteristics without the everyday quality suffers. The reinforced rubbers have asymmetric degrees of hardness. Therefore, despite tighter suspension, the ride comfort is maintained.
Color coding: 1 x red, 1 x green

Hard/Sport SHA82: For racing or the hard-boiled tuning friend who does not mind vibrations, but who places high value on the proverbial driving on rails.
Color marking: 2 x green
