Cylinder Top Performances Black Trophy 70cc

Details
The Black Trophy is Top Performance’s successor to the Trophy cylinder series. 
The cylinders have been modified only slightly; quality and scope of delivery are similar. The Asso piston, however, is now partly molybdenum-disulfide-coated, which improves running smoothness and performance while minimising friction and thus heat development. This set-up therefore makes for improved efficiency and reliability.
