                         Report of Independent Auditors

The Plan Administrator
Polaris 401(k) Retirement Savings Plan

We have audited the accompanying statement of net assets available for benefits
of Polaris 401(k) Retirement Savings Plan as of December 31, 2001 and the
related statement of changes in net assets available for benefits for the year
then ended. These financial statements are the responsibility of the Plan's
management. Our responsibility is to express an opinion on these financial
statements based on our audit.

We conducted our audit in accordance with auditing standards generally accepted
in the United States. Those standards require that we plan and perform the audit
to obtain reasonable assurance about whether the financial statements are free
of material misstatement. An audit includes examining, on a test basis, evidence
supporting the amounts and disclosures in the financial statements. An audit
also includes assessing the accounting principles used and significant estimates
made by management, as well as evaluating the overall financial statement
presentation. We believe that our audit provides a reasonable basis for our
opinion.

In our opinion, the financial statements referred to above present fairly, in
all material respects, the net assets available for benefits of the Plan at
December 31, 2001 and the changes in its net assets available for benefits for
the year then ended, in conformity with accounting principles generally accepted
in the United States.

Our audit was performed for the purpose of forming an opinion on the financial
statements taken as a whole. The accompanying supplemental schedule of assets
(held at end of year) as of December 31, 2001 is presented for purposes of
additional analysis and is not a required part of the financial statements but
is supplementary information required by the Department of Labor's Rules and
Regulations for Reporting and Disclosure under the Employee Retirement Income
Security Act of 1974. The supplemental schedule is the responsibility of the
Plan's management. The supplemental schedule has been subjected to the auditing
procedures applied in our audit of the financial statements and, in our opinion,
is fairly stated in all material respects in relation to the financial
statements taken as a whole.

                    REPORT OF INDEPENDENT PUBLIC ACCOUNTANTS



To the Plan Administrator of

Polaris 401(k) Retirement Savings Plan:

We have audited the accompanying statements of net assets available for benefits
of Polaris 401(k) Retirement Savings Plan as of December 31, 2000 and 1999, and
the related statement of changes in net assets available for benefits for the
years ended December 31, 2000 and 1999. These financial statements are the
responsibility of the Plan's management. Our responsibility is to express an
opinion on these financial statements based on our audits.

We conducted our audits in accordance with auditing standards generally accepted
in the United States. Those standards require that we plan and perform the audit
to obtain reasonable assurance about whether the financial statements are free
of material misstatement. An audit includes examining, on a test basis, evidence
supporting the amounts and disclosures in the financial statements. An audit
also includes assessing the accounting principles used and significant estimates
made by management, as well as evaluating the overall financial statement
presentation. We believe that our audits provide a reasonable basis for our
opinion.

In our opinion, the financial statements referred to above present fairly, in
all material respects, the net assets available for benefits of Polaris 401(k)
Retirement Savings Plan as of December 31, 2000 and 1999, and the changes in net
assets available for benefits for the year ended December 31, 2000 and 1999, in
conformity with accounting principles generally accepted in the United States.

Our audits were made for the purpose of forming an opinion on the basic
financial statements taken as a whole. The supplemental schedule of assets (held
at end of year) is presented for the purpose of additional analysis and is not a
required part of the basic financial statements, but is supplementary
information required by the Department of Labor's Rules and Regulations for
Reporting and Disclosure under the Employee Retirement Income Security Act of
1974. The supplemental schedule is the responsibility of the Plan's management.
The supplemental schedule has been subjected to the auditing procedures applied
in the audits of the basic financial statements and, in our opinion, is fairly
stated in all material respects, in relation to the basic financial statements
taken as a whole.

                           December 31, 2001 and 2000


1. DESCRIPTION OF THE PLAN

The following description of Polaris 401(k) Retirement Savings Plan (the Plan)
provides only general information. Participants should refer to the plan
agreement for a more complete description of the Plan's provisions.

GENERAL

The Plan is a defined contribution plan covering substantially all employees of
the Plan's sponsor, Polaris Industries Inc. (the Company). Effective January 1,
1999, employees from Polaris Sales, Inc. are also included in the Plan. It is
subject to the provisions of the Employee Retirement Income Security Act of 1974
(ERISA).

PLAN OPERATIONS

Certain administrative costs totaling $10,000 and $143,428 for the plan years
ended December 31, 2001 and 2000, respectively, were paid by the Company.
Administrative costs paid by the Company include trustee/asset custodian fees,
record keeping fees, investment management fees, and legal fees for 2000 and
trustee fees only for 2001.

PLAN ADMINISTRATION

The Plan's trustee, Fidelity Management Trust Company (the Trustee), holds and
invests the assets of the Plan and also distributes the retirement benefits upon
instruction from the plan administrator. The Plan is administered by an
executive committee appointed by the board of directors of the Company.

CONTRIBUTIONS/PARTICIPANT ACCOUNTS

Participants may elect to make contributions (limited to a maximum of 15% of the
participant's compensation, as defined in the Plan) to their account balances.


                                                                               5

                     Polaris 401(k) Retirement Savings Plan

                    Notes to Financial Statements (continued)



1. DESCRIPTION OF THE PLAN (CONTINUED)

The Company will make a fully-vested matching contribution to each participant's
account in the Plan of 100% of each dollar of 401(k) contributions up to 5% of
covered compensation. This contribution is intended to satisfy a safe harbor
contribution formula permitted by IRS regulations. By making the safe harbor
matching contribution, the Plan will automatically satisfy the nondiscrimination
requirements which otherwise would apply to 401(k) contributions made to the
Plan.

Plan earnings, as defined, are allocated pro rata based on participants' account
balances.

VESTING

Participants are immediately vested in their pretax and employer contributions,
plus actual earnings thereon.

PARTICIPANT LOANS

Participants may apply for loans from the Plan in amounts of the lesser of 50%
of their vested account balances or $50,000. Loans must be paid back within 5
years; however, this period may be extended to ten years if the loan is utilized
for the acquisition of a primary residence. The interest rate charged on loans
outstanding ranged from 6.75% to 11.50% as of December 31, 2001 and ranged from
9.75% to 11.50% as of December 31, 2000.

DISTRIBUTIONS TO PARTICIPANTS

Employee account balances are distributable upon retirement, disability, death,
termination from the Company, or hardship. Upon the occurrence of one of these
events, a participant (or the participant's beneficiary in the case of death)
may receive his or her account balance as a lump-sum payment or in monthly
payments through an annuity as available per plan provisions.

PLAN AMENDMENT AND TERMINATION

The Company has the right to amend or terminate the Plan, subject to the
provisions of ERISA. In the event of the Plan's termination, all assets of the
Plan will be distributed to participants in accordance with plan provisions.


                                                                               6

2. SIGNIFICANT ACCOUNTING POLICIES AND PROCEDURES

BASIS OF ACCOUNTING

The accompanying financial statements have been prepared on the accrual basis of
accounting.

INVESTMENT VALUATION AND INCOME RECOGNITION

Investments of the Plan are stated at fair value. Shares of registered
investment companies and Polaris Industries Inc. common stock are valued at
quoted market prices, which represent the net asset value of shares held by the
Plan at year-end.

Purchases and sales of securities are reflected on a trade-date basis. Interest
income is recognized when earned. Dividend income is recorded on the ex-dividend
date.

USE OF ESTIMATES

The preparation of financial statements in conformity with accounting principles
generally accepted in the United States requires management to make estimates
and assumptions that affect the amounts reported in the financial statements and
accompanying notes. Actual results could differ from those estimates.

RECLASSIFICATION

Certain 2000 amounts were reclassified to conform to the 2001 presentation.

3. INVESTMENTS

The investment options of the Plan at December 31, 2001 and 2000 consist of
deposits with 14 funds managed by the Trustee, four externally managed funds,
and the Polaris Stock Fund. Participants elect to have their account balances
invested in one or more of the following funds and may change the fund
investment mix daily via a voice response system or the Internet.


                                                                               7

4. TAX STATUS

The Plan has received a determination letter from the Internal Revenue Service
(IRS) dated October 27, 1999, stating that the Plan is qualified under Section
401(a) of the IRS Code (the Code) and, therefore, the related trust is exempt
from taxation. The plan administrator believes the Plan is being operated in
compliance with the applicable requirements of the Code and, therefore, believes
that the Plan, as amended, is qualified and the related trust is tax-exempt.

5. PARTY IN INTEREST TRANSACTIONS

The Plan invests in Fidelity funds and Polaris Industries Inc. stock. These
transactions qualify as exempt party in interest transactions.


                                                                               8
