Sound of Singles®/Battle of Twins®/Sound of Thunder/Modern Roadracing Mission Statement
AHRMA’s mission is to showcase single-, twin- and three-cylinder motorcycles which historically have been under-represented in modern roadracing. The Battle of Twins concept was born in the late 1980s as modern Superbike racing became increasingly dominated by inline four-cylinder machines. BoT racing kept alive the thunderous roar of twin-cylinder machines from British, European and American manufacturers. Sound of Singles racing features modern interpretations of the classic single-cylinder racebike, encompassing everything from production bikes to one-off custom-built machines.
