Info

In 1973, the Lamborghini R 503 and R 603 were introduced. The updated model numbering now indicated the power and number of cylinders. The same lineup also included crawler tractors (e.g., C 503) and narrow fruit-growing tractors (R 503 S). The engine was a 3-cylinder air-cooled 2.8-liter. The transmission was fully synchronized 12+3. The diameter of the dual clutch was 11″.

At the end of the 1970s, the frame color changed from blue to dark gray, similar to the larger Lamborghinis, and at the same time, the design was slightly updated.

The production years of the models are approximate.
