the 700 is a much smoother ride, it doesnt vibrate your balls numb in 20 mins like the yfz's do
of course the power is completely different on them, one is much smaller and higher compression, the other is huge with low compression, the 450 makes good torque down low, but they wana stall if you lug them too much, the raptor can be lugged through anything in 2 gears too high and will just pull right through it, you have to ride them completely different, you have to rev the yfz alot higher to make power obviously, the raptor runs better/faster when u short shift and lug the motor , it takes some getting used to after riding a banshee, keep it a gear higher than you think you should be in and it runs the best, they are a bit tall, but oh well, cant have everything, my friends is widened out and handles good, id take one over a yfz just because of size and comfort, piped for piped they are pretty damn even but remeber the raptor has a much lower compression ratio and much more potential once u start modding them
