Here is the 70cc TOP PERFORMANCES BLACK "TROPHY" kit, this one is made with a good quality "MINACROM" treatment. It has 6 transfers. Its admission as well as its diagrams are reworked allowing an excellent engine torque. The transfers and the exhaust are fine-tuned by hand in the Top performance factory.
The VERTEX Ø48mm piston with a high silicon content has a surface treatment with "Molybdenum disulphide" as well as a small preparation on the rear skirt and on the sides for better opening at PMB and better scanning. In addition, it is in two-segment 1.5mm thick, these are reinforced, hard chrome and domed which allows good acceleration.)
Its cylinder head has a high compression chamber, hemispherical and smooth finish. It is one of the most resistant and torquey kits in its category thanks to its normal exhaust and the quality of its surface treatment.We recommend it to those who want a very torquey material while having a certain strength in order to do a lot of kilometers.
