Maxi kit STAGE6 R/T 70cc x PIAGGIO-Gilera LC

The thermal unit that broke records, lowering the lap time in almost all the stages of the Italian Open Cup and breaking through the 6-second wall in the acceleration races. The modular structure allows mounting by means of bases, in the total absence of passing through priniers, on different motors. The geometry of the transfer and exhaust is therefore no longer limited as it happens on conventional cylinder units, allowing extreme machining, particularly in the BigBore version characterized by a bore of 52mm. Particular attention was paid during the development phase to the thermal of the cylinder. The head, machined entirely by CNC, is fixed at 5 points. Each of these anchors is thermally stabilized by means of its own cooling cheek. Critical points near prisoners, which often lead to seizures, have thus been eliminated. The base, also CNC machined, is fixed to the engine casing, accommodating the cylinder unit through 4 external studs. In the case of MINARELLI engines, the base also performs the task of cooling the thermal unit from below the exhaust port, leading to a further increase in power. For the best-selling Racing exhausts, the appropriate flanges and manifolds will be supplied, alternatively an optional adaptation kit can be used.

STAGE6 R/T MKI PIAGGIO/GILERA 47.6mm H20 70cc aluminum cylinder unit, 39.3mm stroke, 85 connecting rod, 26 horsepower, 12 Nm maximum torque, 1:15.3 compression ratio.

BORING: The cylinder has an insertion diameter into the engine crankcase of 55.70mm. The assembly of the cylinder therefore requires a boring of 56.70m for a depth of 10mm in the insertion area
