does any one know the top speed of a sportsman 450??

 

i know it will at least 45 because thats as fast as my wife was behind me when i was at that speed. ii would guess at least 55 mph.

 

My 2004 Sportsman 400 tops out at 53MPH on flat pavement per the speedometer. The new 450 has a good chunk more power......I'd guess it will do 55/56MPH.

 

I have a friend that claims 58mph.

 

i can believe that my 500 will do 63 64mph on flat road at 7000 rpm... revv limiter lol

 

when we get the wifes 450 broke in ill let you know on hers how fast it will go.

 

My 500EFI will do 55mph into the wind on asphalt. That's taching at 6240rpm. Might squeeze a little more out of it without the wind, but I don't expect it would hit over 60.

 

I had my 04 400 Sportsman at 62 on flat pavement.
Clutching is very inconsistent within polaris machines, and its not unsusual to see one do 60 MPH and another of the same model only do 55. Deflection and alignment is not very good from the factory.
The 62 MPH speed was with a dynojet, k&N filter and heelclicker clutch kit. About 200 in mods.
It would also wheelie in High range while sitting (not standing and pulling on the bars).
With stock setup, anmd just correct alignment and deflection, and correct factory jetting, I could still hit 60 MPH.
I think 62 is about mechanically the limit for the 400 as it was really screaming.

 

that sounds about correct... the 400 and 500 do have the same clutch setup and same engine without the bore on the 400

 

we had the wifes new one up to 52 today w/ 30 milew on it so its not to bad for speed.
