No. I did not mention the 700 but it will do 64-65 mph. There is no way a stock SP400 will do 60mph. Mabey on the speedo, but not by gps. I'm guessing 55 if he's lucky.

 

oh that could be his speedo was 60 on the tar. so the 500 is a good 5-7 mph faster?? is it quite a bit faster in a race?

 

500HO is much faster getting there and probably a good 5mph faster. Basically it will spank the 400 pretty good.

 

a grizzly 660 vs a 500 h.o. is not a fair comparison,
the grizzly will be slightly faster on top end and also quicker
through the powerband.

the comparison should be the grizzly 660 vs the
sp 700(683cc), then it would be a better comparison.
stock, the 660 would be a little quicker off the start
but after a couple hundred yards the 700 would pass
it as it has a little more top end.

now, with a good clutchkit the 700 would give it
a run for it's money at the start and beat the 660
worse at the end of a 200 yard sprint.

we're only talking a couple of mph difference in top end
between the two machines.

 

Snow ride is right,

There is no way a stock sp400 will do 60.

I have a non h.o. sp500 and it will only do
58...I have a 01 sp500 h.o. and it does 62-63 mph..
it's a good bit quicker than the non h.o. and has better
top end by 4-5 mph..

You're doing good to get 60 out of a non h.o. sp500,
it's on the same frame as a 400.. there is no way a 400
will do 60... more like 53-55.. the sp400 engine is not an h.o. engine.

your friends speedo could be reading 60, but it's probably
off a little.

I've ridden with several 500's and I never saw a stock
500 go over 60... (h.o. excluded). in fairness though,
I've only ridden with one 400 and it was no where near
60 on top end.

 

Snowride i would hate to break it to u but my infamous Grizzly will run about 68 mph.....[img]i/expressions/face-icon-small-smile.gif[/img]

 

What mods do you have or how steep is the hill your going down? The speedo on the Grizz is one of the worst of all the brands and at those high speeds, if you compare it to a GPS, you will see it's 5 mph off. That will bring you down to the range I posted. I did say TRUE speed.

 

my friend has a 500 Magnum and it will run 65-68 top end we flipped it one day and some how its since gained 5 mph top end. It will beat our neighbors 700 polaris and a 660 grizzley.

 

wtf is this talk about a magnum doing over 65? also i clocked my cousin on his non h.o. 500 and it does 58mph

 

when we flipped it the throttle got messed up. when we put it back on it gained 5-7 mph some how.
