The history of Harley-Davidson is a long and illustrious one and far too vast for these few pages. There are many excellent books on the subject of the Motor Company at most book stores for those who wish a more complete history. Since the engine is one of the reasons, if not the main reason, the company is so well recognized I will give a brief history of the most famous of their engine designs, the 45¼ air cooled V-Twin.
The first H-D configuration of V-Twin the company produced was in 1909. A few different V-Twin configurations emerged from that initial design but today's engine is an advanced derivative of the 'Knucklehead' first introduced in 1936. The 1000cc and 1200cc Knucklehead engines were produced until 1947 and were the first H-D engine with a combination of a 45¼ air cooled V-Twin with push rod actuated overhead valves and a dry sump lubrication system.
