Fun without complications (6 transfer ports – 2 ring piston) Malossi cast iron thermal units, the first and simplest step to modifying your motorcycl’s engine, are the best choice for continued use of the exhaust system of an approved series or type . For these thermal units, the elevated feature of durability of cast iron is combined with the almost manically high quality standards of Malossi, one of the few companies to demand the most from even this class of thermal units. Into this is inserted the most rigid selections for the joining of the cylinder and the piston, strictly maintained…

The Malossi 180 H2O cylinder kit was born from years of direct development in competition, on the same scooters for which it was originally designed, the Gilera Runner . It's the component for you if you want to convert a 125cc liquid-cooled 2-stroke engine into a 180cc one. Reliable and robust, it ensures effective thermal dissipation even under prolonged stress, keeping the engine at constant temperature and performance over time. The geometry of the head – completely redesigned with a truncated cone dome with a central spark plug, an enlarged exhaust duct, and a third transfer port open at…

CYLINDER KIT Ø 63 ALUMINIUM completely new cylinder kit has been created, designed overall to obtain the maximum result in terms of performance and durability. Every aspect of the system has been studied to maximise the mechanical resistance, the fluid dynamics and improve combustion: the result is a top-of-the-range kit in terms of construction quality and technological development. TECHNICAL FEATURES Cylinder Built from scratch, in high-strength aluminium alloy and cylinder sleeve with nickel-chromium coating. Consisting of an even thickness central core around the cylinder sleeve and the…

Technical specifications Cylinder 4 STROKE Material: primary aluminium alloy with a high content of hardened and tempered silicon, cylinder liner with silicon carbide coating in a galvanic nickel die and crossed smoothing with two diamond passages with very limited tolerances. Machining: on machine tools with high precision numerical control. Cylinder-piston connection with an allowance of 0.05 mm. Recalculated and upgraded heat exchange surfaces. Piston Ultra compact with 3 rings. Material: special aluminium alloy with high silicon content, low thermal expansion and a tin facing on the…

Technical features Material: special aluminium alloy with high percentage of silicon and titanium that guarantees exceptional strain strength even at high temperatures. Heat treatment: special quenching and stabilizing treatment that gives the material increased toughness and strength, guaranteeing that mechanical and size specifications will remain unaltered for temperatures of up to 250 °C. Chip-forming machining: carried out on NC machining centres with extremely-limited size and shape tolerance (roundness, perpendicularity). Inner surface coating: effected using silicon carbide on a…

ALUMINIUM CYLINDER Cylinders obtained by gravity die-casting in permanent steel moulds. Material: hardened and tempered high silicon content primary aluminium alloy. Machining: on numerically controlled high precision machine tools. Cylinder liner with silicon carbide metal-spray coating on a galvanic nickel matrix, cross-honed with passes with diamonds for very tight tolerances. Heat exchange surfaces recalculated. Exhaust and transfer ports designed and tested for maximum thermodynamic performance. Rings in very strong nodular cast iron with ground, wear-resistant, hard chrome metal-spray…

VESPA NEVER DIES Aluminium cylinder kit Ø 68,5 Afurther upgrade for the timeless Ø 68.5 cylinder kit! 1983 The aluminium cylinder with 68,5 mm diameter - turning point in Vespa tuning - was born. Made of Nicasil aluminium, with super light piston and 1.2 mm semi trapezoidal rings, it becomes a legend, a real musthave for all Vespa fans. 2008 The cylinder is updated, by adding the head with hemispherical combustion chamber and central spark plug. 2013 The cylinder, always made of Nicasil aluminium, has been completely changed concerning both main and rear ports and exhaust port as well.…

CAST-IRON CYLINDER KITS Malossi is glad to present the new line of cylinder kits which have been designed for the latest generation scooters. They are unique tools able to defeat the traffic black-out of our cities. They are highly reliable and they have an exceptional torque. They have been studied to support a prolonged stress and can offer high accelerations even on highly pendent roads. They do not know neither fatigue nor wear. Cylinders made of selected lamellar cast iron alloys with recalculated cooling surface. Strengthened pistons made of aluminium alloys with high silicon content,…
