Here’s your chance to win a signed copy of Le Vack’s Legacy: J.A.P – an authoritative account on the first British double-overhead-camshaft motorcycle racing engine.

In 1922, the largest supplier of proprietary motorcycle engines in the world, J. A. Prestwich & Co (aka JAP), decided to go racing with something unique. The result was the first British double-overhead-camshaft motorcycle racing engine.

In Le Vack’s Legacy, Brian Thorby traces the fortunes of the small number of JAP racing engines and parts that have wandered Europe for nearly a century.
