This kit boasts a 67mm bore and a 47mm stroke, yielding a substantial 166cc displacement. Constructed from a primary aluminum alloy enriched with hardened and tempered silicon, it ensures excellent heat dissipation and durability. The cylinder liner features a silicon carbide coating with nickel die and cross-smoothing for precision and longevity. Machining is performed on high-precision numerical control machine tools, maintaining a tight cylinder-piston tolerance of 0.05mm.\n\nThe included piston is ultra-compact with three rings, crafted from a special aluminum alloy with high silicon content and low thermal expansion, further enhanced by a tin layer on its sliding surfaces. A three-piece scraper ring made of chrome-plated special steel alloy completes the set.\n\nThis performance-oriented cylinder kit is exclusively compatible with the Malossi Force Master 2.1 control unit. It is designed for a wide range of Aprilia, Derbi, and Italjet models, including specific fitments for Euro 3, Euro 4, and Euro 5 variants.
