I don't know about the Sportsman, but my Scrambler with the same 500 H.O. engine will do 65mph.

 

my rubicon will do about 58 , but the scrambler is more sportier than a sp 500

 

The Scrambler is a lot lighter, that is why it can go 65...Does the rubicon have a chain and sprocket, or is it shaft drive....the final drive will play a big part as to what the top end speed is...you either get low end power or top end speed. You can't have both. The Scrambler is chain driven so you can adjust the final drive to determin what you will get. A smaller front sprocket (fewer teeth) will giveyou more low end. The more teeth on a front sprocket the better top speed. The Sportsman does not have that option with a shaft drive. It is what it is...the rubicon might have a a higher gear ratio giving it better top end speed. that whould explain the faster speed than the Sportsman....my 2 cents

 

Stock 2009 500ho is 57mph

 

How about the 500 EFI? What is the top speed?

 

How about the 500 EFI? What is the top speed?

 

Top speed depends on alot of variables. Does the rider weigh 125 or 300 pounds? What type of surface are they on? Wind, any slope.. etc. It is not really fair to say x will go y m.p.h.

 

50 efi is prob still the same as the h.o. but correct me if im wrong

 

i think the 500 efi would probually be the same as the h.o., just gets there a little faster

 

When I had my 02 400 SP I had it up to 59 mph on level pave according to the speedo & I weighed about 250 at the time. It was completely stock.
