Here is the beautiful kit from ATHENA called sport. This 70cc with a diameter of 47,6mm with 10mm axle is manufactured with the highest quality aluminum market. It really allows for maximum strength while keeping a reasonable price. This kit is equipped with a normal head and a single-piston semgent 1mm for minimal friction and therefore greater ease to reach the highest speed. These diagrams are very well worked, seen on the rise with an almost perfect finish. In clear this kit is an excellent performance gain without neglecting the time reliability.
