Current Business Update N.A. retail sales trends for the third quarter 2008 thru mid-September: Polaris side-by-side vehicle retail sales continues strong Industry core ATV retail sales remain weak; Polaris retail sales performance is modestly outperforming the Industry Victory motorcycle retail sales continue to grow modestly but less than expectations in a N.A. heavy weight cruiser and touring market that remains soft Consumer credit availability from HSBC and GE combined, remains at acceptable levels Commodity cost pressures continuing; offsetting somewhat with price increases July dealer meeting was a success Introduced MY 2009 products for ATVs, RANGERS and Victory motorcycles Dealers excited about new MY 2009 new products including two all new Sportsman XP models; completely redesigned RANGER(tm) side-by-side models and a new RANGER(tm) heavy-duty and RZR S model; two new Victory motorcycle models and a new more powerful Victory engine in select models Dealer orders for each product line met or exceeded Company expectations During the dealer meeting Polaris introduced a retail sales/order process called Max Velocity Program (MVP) that Polaris will begin testing in the Northeast region A more effective and efficient dealer retail sales driven process Dealer orders for Polaris product made as frequently as bi-weekly based on retail sales levels Approximately 150 dealers in Northeast U.S will be included in this test phase Given current business trends Polaris anticipates that it will meet or slightly exceed it's current third quarter 2008 sales and earnings per share guidance range

2008 Year Guidance - Full Year 2008 Full year 2008 earnings from continuing operations is expected to be in the range of $3.40 to $3.48 per diluted share, up 10% to 12% from $3.10 in 2007. Sales growth for full year 2008 is expected to be in a range of up 9% to 11% from 2007 sales of $1.78 billion. Sale guidance by business: ATVs, including RANGER(tm) - Up 9% to 11% Snowmobiles - Up mid teens percent Victory Motorcycles - Down low double digits percent PG&A - Grow slightly faster than overall Company sales growth Gross margins expected to expand up to 80 basis points - Third Quarter 2008 Third quarter 2008 earnings from continuing operations guidance range is $1.07 to $1.11 per diluted share up from Q3 2007 earnings of $1.07 per share. Sales in third quarter 2008 is expected to be up 2% to 5% from Q3 2007 due primarily to continued growth from the RANGER side-by-side vehicle business, including the very successful RANGER RZR(tm) and PG&A sales growth resulting partially from higher side-by-side related PG&A sales .
