Comparing 2025 Big Boy Monster Utility 250 vs 2025 KAYO AYAY 70 vs 2025 Yamaha Wolverine RMAX4 1000 — Common Questions
Which has the most powerful engine?
The 2025 Yamaha Wolverine RMAX4 1000 has the largest displacement at 999cc, making it the most powerful in this comparison. A larger engine generally means more torque for towing and off-road work.
Which quad is the lightest?
The 2025 KAYO AYAY 70 is the lightest at 82kg (dry weight). A lighter quad is easier to manoeuvre on trails and simpler to recover if stuck.
Which is best for farm work and towing?
For heavy farm use the 2025 Yamaha Wolverine RMAX4 1000 has the highest towing capacity at 680kg. 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.
