ERLA Speedway Machines (Germany)

The German ERLA lends its name from the first two letters of its designer's first and last name, Erich Lawrenz.

The ERLA (Desmodromic)

This machine was also made by Erich Lawrenz and was just finished before he sadly died. The engine on this particular machine is made from a Godden crankcase, and on top, the head from a Desmo 916 Ducati engine.

In the head there are 4 Valves, whilst the cylinder is home made and furthermore, it is watercooled. For a clearer explanation of what is meant by a "Desmodromic" engine, take a look at the Frank Arnott design.
