More info

    • Harley-Davidson® motorcycles modified with some performance engine parts must not be used on public roads and, in some cases, may be restricted to closed-course competition. Those performance parts identified with a stop hand symbol are U.S. EPA legal, but are NOT legal for sale or use in California on pollution-controlled motor vehicles. California guidelines on tampering can also lead to substantial fines and penalties.

    Note

    Installation of automatic or manual compression releases on large displacement engines is highly recommended.

    Caution

    Installation of California performance kit onto a 49-state model motorcycle or a 49-state performance kit on a California model motorcycle will void manufacturers warranty, as it will not result in a street compliant configuration.
