    The sleeve of S821B is revolutionary for the off-road class; it is manufactured with a special 8 ports system and an exaust with “booster” to increase the power and to take care of the fuel consumption.

    It is of sliding type without Venturimeter, realized in nylon, double regulation, diameter 8 mm .

    Long stroke
    The long stroke of this engine, 16.80 mm with a bore of 16.26 mm, allows having a high torque at low rpm.

    Rear ball bearing
    The outer diameter of 25.80 mm has been adopted in order to avoid ring distorsions and to increase fatigue resistance.
