British Anzani Twin cutaway

Another fine cutaway by F.W. Beak. The British Anzani two cylinder two stroke motorcycle engine was introduced in 1953 in two sizes, 242cc and 325cc. Based on an outboard engine, the cases were horizontally split and the carb breathed though a rotary disc located in the center crank bearing area.
 The engines were used by Norman, Cotton and Greeves among others.
