Description
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 and, with their unprecedented capacity of 70 and 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 confi guration 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 profi les specifi cally designed to increase the torque and feeling of the engine, now much brighter and even more progressive. The head cover is made of forged aluminium, red anodized and lathed in high precision CNC machines.
