Comparing 2006 Yamaha Bruin 350 Automatic 4X4 vs 2020 Yamaha Raptor 90 — Common Questions

Which has the most powerful engine?
The 2006 Yamaha Bruin 350 Automatic 4X4 has the largest displacement at 348cccc, 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 2006 Yamaha Bruin 350 Automatic 4X4 is the lightest at 243kg (dry weight). A lighter quad is easier to manoeuvre on trails and simpler to recover if stuck.
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.
