The pistons are heat-treated with a T-6 hardening and tempering cycle. Also, a molybdenum disulphide skirt coating is used for reducing wear and improving the break-in phase of each piston.\n\nCast Pistons for 2 Stroke\n\nBecause of a cast piston’s ability to contain higher silicon content compared to forged pistons, and because two-strokes have lower cylinder pressures when compared to four-strokes, cast pistons are ideal for two-stroke engines. Vertex pistons are gravity cast from an aluminum alloy with 18% silicon content. Silicon is important because:\n\nIt decreases thermal expansion, which changes the geometry after the piston reaches operating temperature. With low thermal expansion characteristics, Vertex pistons can be run at tighter tolerances compared with forged pistons. This creates better power and performance, also making them less susceptible to rattling or breaking.\n\nSilicon gives the pistons better wear characteristics and prolongs piston life by decreasing wear on the piston skirt.\n\nFlat top single ring\nRing part number 53009805400\n\n\n","brand":"VERTEX","offers":[{"title":"PISTON KIT VERTEX 53.95MM RACE GAS GAS MC HUSQVARNA TC TE TX KTM EXC SX XC W","offer_id":43139216212016,"sku":"24243B","price":233.95,"currency_code":"NZD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0031\/4012\/4739\/files\/9b31cefa841119ab40c951daaa314fc3_1896fca3-d2c1-433f-8c3f-66f2c33ab3bb.jpg?v=1780054827","url":"https:\/\/www.moto1.nz\/products\/piston-kit-vertex-53-95mm-race-gas-gas-mc-husqvarna-tc-te-tx-ktm-exc-sx-xc-w","provider":"Moto1","version":"1.0","type":"link"}
