Previously offered by us as Stage6 Sport Pro 70cc - Athena Sport Pro 70cc. This is a high-quality aluminum cylinder at a price comparable to cast iron cylinders. The Sport Pro 70cc is a very powerful Mid Race cylinder - between the regular Sport and the Racing 70cc. Specially constructed channels, perfect times - together they give incredible torque. Everyone knows the excellent heat dissipation of aluminum cylinders. The Athena Sport Pro 70cc kit is supplied with the head, piston, ring, pin, pin locks, gaskets and diaphragm plate. Lots of potential. Reaching 9 HP with an appropriate exhaust, for example Yasuni Z or Giannelli Rekord / Reverse, and a 19 / 21 mm carburetor is absolutely possible. By using the right parts and making appropriate modifications to the Athena Sport Pro kit, you can achieve more power than stated above. Cylinder with a piston for a 10mm pin - make sure before ordering.
