(1)     The Plan provides for possible adjustment of the number, price
        and kind of shares covered by options and other stock incentive awards
        granted or to be granted in the event of certain capital or other
        changes affecting the Registrant's Common Stock.  This Registration
        Statement therefore covers, in addition to the above stated 1,250,000
        shares, an indeterminate number of shares that may become subject to
        the Plan by means of any such adjustment.  

(2)     Pursuant to Rule 457(h), estimated solely for the purpose of
        computing the registration fee, based upon $68.875 per share, which is
        the average of the high and low sales prices of the Registrant's Common
        Stock as reported on the New York Stock Exchange Composite Tape on June
        23, 1994.  

(3)     The actual offering price will be determined in accordance with
        the terms of the Plan.

Briggs & Stratton Corporation
12301 W. Wirth Street
Wauwatosa, Wisconsin  53222

Gentlemen:

        We are providing this opinion in connection with the Registration
Statement of Briggs & Stratton Corporation, a Wisconsin corporation (the
"Company"), on Form S-8 (the "Registration Statement"), filed under the
Securities Act of 1933, as amended (the "Act"), with respect to the proposed
sale by the Company of up to 1,250,000 shares of Company Common Stock, par value
$0.01 per share (the "Shares"), upon the exercise of options granted under the
Briggs & Stratton Corporation Stock Incentive Plan (the "Plan").  

        We have examined (i) the Registration Statement, (ii) the Company's
Articles of Incorporation and Bylaws, (iii) the Plan, (iv) the corporate
proceedings relating to the adoption of the Plan, the issuance of the Shares,
and the organization of the Company, and (v) such other documents and records as
we have deemed necessary in order to render this opinion.  In rendering this
opinion, we  have relied as to certain factual matters on certificates of
officers of the Company and of state officials.

         Based upon the foregoing, it is our opinion that:

         1.      The Company is a corporation duly incorporated and
                 validly existing under the laws
 of the State of Wisconsin. 

         2.      The Shares, when issued and paid for as contemplated by
                 the Registration Statement and the Plan, will be validly
                 issued, fully paid and non-assessable by the Company, subject
                 to the personal liability which may be imposed on shareholders
                 by Section 180.0622(2)(b) of the Wisconsin Business Corporation
                 Law, as judicially interpreted, for debts owing to employees
                 for services performed, but not exceeding six months service in
                 any one case.  Although Section 180.0622(2)(b) provides that
                 such personal liability of shareholders shall be "to an amount
                 equal to the par value of shares owned by them respectively,
                 and to the consideration for which their shares without par
                 value was issued," the Wisconsin Supreme Court, by a split
                 decision without a written opinion, has affirmed a judgment
                 holding shareholders of a corporation liable under the
                 substantially identical predecessor statute in effect prior to
                 January 1, 1991 (Section 180.40(6)) for unpaid employee wages
                 to an amount equal to the consideration for which their par
                 value shares were issued rather than the shares' lower stated
                 par value.  Local 257 of Hotel
