Overview

Briggs & Stratton Racing Engines is the racing division of Briggs & Stratton Corporation, specializing in high-performance engines for kart racing and junior drag racing. It holds a dominant position in sanctioned karting, providing engines, parts, and racing gear through a network of motorsports centers. The division is notable for producing the most racing engines of any single company and supporting events like the NHRA Junior Drag Racing League.

History

Briggs & Stratton Corporation, founded in 1908 by Stephen F. Briggs and Harold M. Stratton, entered racing involvement shortly after its first engine production in 1919. The company expanded into sanctioned kart racing nationally in the early 1980s and formally launched its Racing Division in 1991 to serve this market. Key milestones include support for NHRA Junior Drag Racing starting around 1991 and ongoing production of engines like Raptor and Blockzilla for half-scale dragsters.
