Cylinder Kit LC Malossi MHR Testa Rossa 94cc Piaggio

The new generation BIG BORE engine. Solid cylinders, only for liquid-cooled scooters (7 ports and exhaust crosshead - 1-ring piston - modular cylinder head - mandatory bore of the original crankcase or the Malossi C-One crankcase - crankshaft with connecting rod different from the original one). Derived directly from the seven-port technology, which powers the revolutionary Flanged Mount, the BIG BORE Testa Rossa cylinders represent the latest success achieved thanks to the efforts and studies that Malossi has continued to dedicate to engines intended for the original Piaggio and Yamaha crankcases and, with their unprecedented displacement of 94 cc, they allow the BIG BORE family to take a significant leap forward. Externally almost indistinguishable from their flanged counterparts, the BIG BORE Testa Rossa cylinders feature a stud frame compatible with both the original engines and the Malossi C-One crankcase. The interior is also completely similar to the Flanged Mounts, thanks to the famous seven-port configuration and a double exhaust port, the only difference being the limits set by the internal passage of the bolts which affect the size and development of the exhaust. The head is again modular, with new internal profiles specifically designed to increase the torque and feel of the engine, now much brighter and even more progressive. The cylinder head cover is made of forged aluminum, anodized red and turned in high-precision CNC machines.

The new generation BIG BORE engine. Stud bolts, only for liquid-cooled scooters (7 ports and exhaut crossbar - piston with 1 segment - modular head - required boring of original case or C-One Malossi 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 and, with their unprecedented capacity of 94 cc, they allow the BIG BORE family to make a significant leap forward. Externally almost indistinguishable from their flanged counterparts, BIG BORE Testa Rossa cylinders feature a stud bolt framework compatible both with original engines and with the C-One Malossi case. Even inside they are totally similar to Flanged Mounts, thanks to the renowned configuration with seven ports and dual exhaust port, with the only difference given by the limits set by the inner passage of the bolts that affects the size and development of the exhaust. The head is once again modular, with new internal profiles specifically designed to increase the torque and feeling of the engine, now much brighter and even more progressive. The head cover is made of forged aluminum, red anodized and lathed in high precision CNC machines.
