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.
