Meet Shovelhead and Blockhead... and their owners, Mike our long-time timber frame artisan, and Brady, a long-time precision moulder expert at Pioneer Millworks. Here they compare their big twin engine styles. The Shovel, as it's more commonly called, was made from 1966 to 1984 until it was replaced by the Evolution, the official name of the engine style from 1984-1999. Check back throughout the summer as there are lots of bikes around here, plus we hear Andy just bought a Harley, too.
