just looking at buying a 04.5 sp 500 HO i have a 500 magnum now and kind of find the power to be alittle on the shallow side so what i was wondering was what is the real pwr gains in the HO from the regular 500????......and i don't really want a 600 either...

 

anyone??

 

My dealer told me that the 500 HO is 40hp. I think that the old 500 was 32hp but I am not sure. Hope that helps. BTW, the dealer also told me that the 700 is 48hp.

 

The 500HO motor puts out about 38-39hp at the crank. It has a reported 20% increase in power over the non HO 500

 

About 18 months ago I was test driving a few quads at a Polaris dealership with a friend. I test drove a 500 Magnum RMK, 400 Sportsman & a 500 HO Sportsman. Now I already own a Polaris Xpedition 425 (same cc's as the 400 sportsman) which I like very much. But after riding these quads over the same trails this is what I thought. The 400 & 500 absolutely killed the Magnum in the comfort area. The magnum rides like mine, very nice, until you ride the IRS of a Sportsman. The 500 Magnum was a little more powerful than the 400 Sportsman but not enough to pick it over the Sportsman's ride. The real problem was the 500 HO. It had a ton more power than the rest. So much more it's hard to believe it until you experience it yourself. You can notice it thruout the power band. Low end, midrange, uphills & top end. It was the first time I wish I had paid a little more and got the 500 HO over my Xpedition. Needless to say my friend bought the 500 HO.

go test ride 'em somewhere over the same trails. It was very clear to me, my next quad will be the 500 HO.

don't quote me on these
325cc Magnum approx 20 HP
425cc Sportsman approx 27 HP
500cc Sportsman/ Magnum approx 32 HP
500cc HO Sportsman approx 38+ HP

 

The 500 H.O. uses the same base Engine as the Scrambler 500, but changed a little. so you know it definetly will outpower the older 500's like my '98 Sportsman. polaris claims 30% increas of power at the crank over the older version. so yes the H.O. is the more powerful atv. i like mine the way it is, but i might get one of the new H.O.'s anyway, they are nice.
