I have an 800 sportsman I have had about 1 month before buying I did some research and the top speed was suposed to be around 70-75 mph, acording to my speedo mine is topping out around 55, I have heard rumors of tranny problems do I need to be worried, If not are there an mods to help me get more top end?
I already have a K&N air filter. Thanks.

 

no sportsman will do that speed stock. yours should be around 65 mph. i hear there was some gear issues in 05 put polaris fixed the problem in 06

 

Wait until they put the KTM 950 V-twin motor in one and then trade yours in. [img]i/expressions/face-icon-small-wink.gif[/img]

 

I thought the magazines said the polaris 800 should run around 68-70 stock.

 

My brother-in-laws 06 800 runs 68mph on flat road with GPS.

 

What kind of engine mods. can I add to a 07 800X2 without voiding the warranty? I'm looking for at least 75 mph.

 

look for a differnt bike then. lol. j/k i dont beleave you could anything to to it to do that unless it involves replacing stock parts and would not be warranteed. just a guess.

 

If you are looking for a 75mph quad, buy a sports bike like the 700efi raptor or the can-am 800 renagage. BTW, why do you want a 4x4 utility quad that does 75mph?

 

I'd hate to be on the back of an ATV going that fast.

 

mine ran 75 by the speedo stock with a k@n
