Industry’s First 4-2-1 Sidewinder Design

Specifically designed for use without wheelie bars, Brock’s 4-into-2-into-1 sidewinder (the industry’s first) provides the most average power and torque with a megaphone-induced peak power punch. Unique configuration allows maximum performance from stock displacement to big cc engines. Years of knowledge, acquired from Brock himself professionally drag racing street bikes, are merged into a purpose-built side exit system.
