Comparing 2020 Kawasaki Brute Force 750 4x4i EPS Camo vs 2006 Yamaha Grizzly 660 Automatic 4x4 Ducks Unlimited Edition — Common Questions

Which has the most powerful engine?
The 2020 Kawasaki Brute Force 750 4x4i EPS Camo has the largest displacement at 749cc, making it the most powerful in this comparison. A larger engine generally means more torque for towing and off-road work.
Which is best for farm work and towing?
For heavy farm use the 2020 Kawasaki Brute Force 750 4x4i EPS Camo has the highest towing capacity at 567kg. For general farm duties any quad with 4WD and a towing rating above 400kg is suitable for light implements, spray rigs and game-reserve work.
Which has the better suspension?
Independent front suspension (A-Arm or IFS) absorbs bumps better than solid-axle designs and improves handling on uneven terrain. Check the Suspension category in the full table above to compare front and rear travel for each model.
Which is the easiest to ride?
CVT automatic transmission is easiest for beginners — there is no gear-changing or clutch to manage. A lower seat height also makes a quad more accessible for shorter riders. Check the Transmission and Seat Height rows in the table above.
