ok everybody i have owned both brute force and grizzly ,i bought both new,the grizzy have bad efi systems the power sterring just breaks axles to easy i broke a compresson ring on it after 500 miles its really a junky four wheeler,tha brute force i haue now is tha best i every owned ive never broke and axle and i have 32 silverbacks on it i had starter trouble but it was under warrent i have tha jets in tha carb full muzzy exhaust dinateck chip mine has 73 horse power i have never sliped a belt i pulled a 50 ft cotton wagon with mine in high range brute force is the only way 2 go and by tha way mine has stock axles with 32s silverbacks

 

I am no expert but my ac 450 does 55mph and i ran out of room. If the BF and grizzly have the space they should do at leatst 65mph stock no prob

 

I've had prairie and a brute was worst ATV I have ever owned EVER hands down most unreliable, hot running ,belt burning, tranny wrecking, diff leaking, shifter out of adjustment, water in the air breather, overpowered thing EVER! if you wanna go in a straight line fast get the brute..but that thing will eat more parts than gas..

Get the Grizzly those are good machines very tough and long lasting and more than enough power than anyone would ever need even in stock form.

 

WOW, I haven't heard too many complain about their brute forces. I never had a single problem with my bf750.

 

The Kawaski also has EFI 2011 Kawasaki Brute Force® 750 4x4i ATVs

The one thing the BF might be better at is high speed riding on faster fire and logging roads being that its a twin cylinder while the Grizzly is a single.

 

Maybe when he posted that 4 years ago they didn't have EFI.
