Italian piston specialist Vertex (VP Italy) has further new product lines for this year that were introduced at EICMA in November 2015.
Among them were new 2 and 4-stroke scooter pistons that are described as designed to “improve and optimise the performance of the most popular 2016 scooter models”.
Specific piston designs are offered for the Yamaha T-Max 530, available in OE Replica and High Compression versions, and for other makes and models such as the Piaggio Vespa ET 4 and Leader 125 4T, Aprilia D-Tech injection 50 2T and for Honda SH 125 4T.
Vertex 2-stroke pistons are cast rather than forged, so they can hold a higher silicon content. Because 2-strokes have lower cylinder pressures compared to 4-strokes, Vertex say their gravity cast aluminium alloy 2-stroke pistons can contain 18 percent silicon, decreasing thermal expansion. This means they can operate at tighter tolerances compared to forged pistons and deliver better wear characteristics, prolonging piston life by decreasing wear on the piston skirt.
