Big Bore Testa rossa Cylinder kits The new generation BIG BORE Testa rossa cylinder kits! Stud bolts, only for liquid-cooled scooters. (7 ports and exhaust crossbar - piston with 1 segment - modular head - required boring of original case - engine shaft with connecting rod different from the original). Deriving directly from seven port technology, which animates the revolutionary Flanged Mount, BIG BORE Testa Rossa cylinders represent the latest success achieved thanks to the efforts and studies that Malossi has continued to devote to engines intended for original Piaggio and Yamaha cases…

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…
