 The VERTEX piston Ø 47mm high silicon content has a superficial treatment "Molybdenum disulphide" as well as a little preparation on the arrest arrested skirt and side opening for better PMB and better scanning. In addition, it is bi-segments of 1.5mm thick, they are reinforced, hard chrome and curved allowing it good acceleration. 

 
Its head has a high-compression chamber and tapered finish polie.C'est one of the most durable and torquey kits in its class thanks to its normal exhaust and the quality of its surface treatment.
