Comparing 2019 Suzuki KingQuad 400 FSi vs 2019 Yamaha Grizzly 90 — Common Questions

Which has the most powerful engine?
The 2019 Suzuki KingQuad 400 FSi has the largest displacement at 376cc, making it the most powerful in this comparison. A larger engine generally means more torque for towing and off-road work.
Which has the better suspension?
