went riding this past weekend and after just riding around, breaking it in, at end of day i had 15 hrs on it so when we got to power lines my buddy with polaris 500 h.o. desided to run me, wrong! i nailed it and let her roar and my grizz kicked his ***... i hit 67 before i had to hit brakes... end of lines. i think she would of gone a lil more if not... what a ride! by bye polaris!

 

About 300 miles per hour.. straight down, if you drop it out of an airplane, from 50k feet.

On a trail, fast enough that if you hit a big tree it's gonna really really hurt...

All speeds with 89 octane on pavement.

Best downhill speedometer- 69mph
Best flat speedometer- 66mph
Flat GPS- 60.0mph (speedometer read 65mph)

All stock everything. That is as honest as I can get. In other words, it won't do a true 65 on a gps on flat pavement like I've heard so often.

 

My two friends that have Grizzly 600 both there Speedometers are 7 MPH fast at top speed when you compare it too a GPS the 660 from what I heard is the same. Just a FYI

 

Ive only tried once to get mine up to top speed, I hit 58(speedo) before I had to let off. Man, thats fats enough for me!

 

Geeze if that's 'fast enough for you' why'd you buy one? There are other machines more suited for driving slow like the AC 500 ect.

 

58mph is fast enough. However, I like the fact that I can get there quickly! One of my main reasons for buying the BIG Griz is the power to turn the bigger mud tires I will eventually put on it.
