Well you can call it unlikely if you want but it happened. Call it rider, call it what you want. Fact of the matter is, it happened.

 

You don't have nothing to worry about...The Prairie 700 V-twin will beat a Grizzly fairly easily!!
700cc V-twin vs. 660cc big single= no contest, the V-twin with bigger displacement has more power.

 

Tell that to grizzly rider who says a stock grizz beat a modded 750Vtwin!!??

 

Either the BF 750 had serious problems or the guy is lieing!!!

 

I have a 06 BF750i and my father in law has a 06 grizzly and I can spank his a$$! Both are all stock except the Brute has ITP tires on it.

 

I love these V-Twin engines!! Now i wish Kawi would make an 800 V-Twin quad, and Arctic Cat would take that motor and use it!! I would love it.

 

Ignore the people who keep say bigger tires make a ATV go slower. Thats crap. The bigger the tire the more ground covered per revolution of the engines cycle. The small the tires, The more revolutions needed to maintain the same speed.

Top speed ****guessing**** is 55mph</end quote></div>


LOL My old 23hp Honda 450 Forman could do 50mph. My freinds 42hp 03 660 grizzly can hit 65mph without a doubt .

You might go faster but you will loose acceleration as the "torque" required to turn that bigger tires increases! Which is why any body who puts a lift and bigger tires on their 4x4 trucks re-gears to get that "Snap" back... On ATV's people put in clutch kits to get their "Snap" back. I rode with a guy who has 27" Mudlites on his Popo 500 and he rode around most of the day in LOW range to keep that "Snap" while I simply stayed in high range.

Also bigger tires will change the Speedo reading to be faster than actual speed for the same reason you stated.. I don't think you can re-calibrate ATV's to read actual speed once you go to a bigger tire. This is usually accomplished in trucks by changing the speedo gear on older rigs or re-calibrating the computer on modern rigs.

And to finish my $0.02 unless you are racing who cares if you don't win a drag race or your utility quad goes 2-3 mph slower than you buddies... 60 mph is more than fast enough on these Grizzly's... Unless you have it decked out with Ohlins, Works or ELka shocks like DV.... So check the testosterone at the door will ya?

 

I have to agree with Steve.

Larger tires will probably increase top speed (if there's enough HP avail.) because it will effectively change the overall gear ratio. But this will also reduce torque and acceleration, and torque in a utility ATV is what you want.

I too don't understand why people are concerned about whether one utility quad will be faster than a buddies utility quad. It's not about top speed. If it were, then you are probably riding the wrong type of ATV and need to consider a sport quad and do lots of mods to make it a drag quad.
