Italian off-road pistons and performance specialist Vertex launched a new version of 2-stroke off-road pistons at EICMA.
Called the 'Race Evolution' line, these "exotic pistons have been tested by our existing supported racing teams and are specifically for racing applications and stand out from the other high performance product lines we offer by having a reduced top land, a special 0.8 mm piston ring, special MoS2 coating and specific pockets to facilitate cylinder/piston smoothness and a new special dedicated racing profile.
Molybdenum disulphide (MoS2, or moly) is an inorganic compound composed of molybdenum and sulphur. Classified as a transition metal dichalcogenide, it is relatively unreactive and unaffected by diluted acids and oxygen. In appearance and feel, molybdenum disulphide is similar to graphite. It is widely used as a dry lubricant because of its low friction and robustness.
'Race Evolution' pistons are already available for selected Yamaha (YZ125), KTM (125/85/65) and Husqvarna 125/85/65 models, with more applications to follow.
