The Raptor engine’s role in racing dates back to before the Briggs & Stratton Racing division began in 1991. The workhorse of our racing line for almost 20 years, this engine line CEASED production in 1999 due to impending E.P.A. regulations. We ask that you contact your source of supply about parts availability as many parts have been discontinued.
