A13 (1974)
The 1974 A13 is a 1288cc engine with new tall-deck block casting. It has 73mm bore like the A10 and A12 before it, but with stroke increased to 77mm. This one-year-only model was designed for the American market, to keep the same relative performance with new B210 which was considerably heavier than the B110. Compression ratio reduced to 8.5:1 to help meet US emission control standards, yet the increased displacment resulted in 75hp. To accomodate the longer stroke, the 1974 A13 features a "tall-block" casting with a deck height 15 mm (0.59 inch) higher than previous A-series engines.
