Vertex Pistons - 2 and 4-T options for 2025 models
Building on a season of success on the race tracks of Europe and beyond , one in which the MXGP Vice- Champion title of the Slovenian Honda HRC Tim Gajser and the WMX title of the Spanish Daniela Guillen stand out , riders on bikes equipped with Italian made Vertex pistons have won as many as five world titles in Enduro . These successes include in the E3 the Beta Factory rider Brad Freeman , and in Supermoto the German Marc Reiner Schmidt , becoming the undisputed protagonist of the S1 . The feedback from these successes has already found its way into Vertex ' 2025 line of off-road motorcycle products , and as a result of the development work done with Motocross , Enduro and Supermoto factory riders and teams , Vertex already has an updated range of performance pistons for the manufacturers ' 2025 motorcycle range line-ups , including its four stroke high-performance lines - the Replica , High Compression , Big Bore and GP ' Racers Choice ' versions . Similar to the ones used by Tim Gajser ' s Honda HRC , ' Racer ' s Choice ' pistons are made from hot forged , high-strength aeronautical alloy and have an exclusive shape with internal support crosspiece derived from Formula 1 . This racing profile and specifically derived piston head shape allows for the maximum compression ratio - so as to improve power and lowend torque without compromising reliability
Coated with molybdenum disulfide to ensure smoothness and wear resistance , a DLC-coated pin , anti-rotation retaining rings and segments with a special PVD treatment make ' Racer ' s Choice ' " a top of the range Vertex performance piston option that is respected in the paddocks of all the major series throughout the world ". There are also four different two stroke ranges to choose from - Replica , Race , the Race Evolution , that is aimed at those seeking maximum performance with total reliability , and the recently updated new
Pro-Race range of forged pistons . These all have a molybdenum disulfide coating that improves smoothness and adaptation to the cylinder , to guarantee the best possible thermal performance .
