yfz because of the twin cam design
yfz450
Outlaw 525, by far.
I have both and I think it depends on the driver
That is something you will need to research on your own. The horsepower ratings are Honda 450R 42 hp and the YFZ 450 39 hp. But you are as aware as I am that hp ratings aren't the whole story, especially in the dirt. yamaha450-i don't care what people say a yfz450 is faster than a trx450...acceleration and top speed...a yfz is lighter (approx 100pounds) but a trx is said to last longer...honda is know for quality...but my yfz has been fine except for the water seal breaking...so as long as you service it properly I would go yfz
yfz is fater because has shooter gear through 1-4 but when you hit5 it is longer
a stock yfz450 goes about 75 mph
yfz450 nerf bars fit banshee
The top Speed of a Stock YFZ450 can be 92-93mph but if modified it can go up to 115 mph The top Speed of a Stock YFZ450x can be 95-97mph but if modified it can go up to 117 mph. The YZF450x is faster because it is lighter
yfz450 is a Yamaha sport 4 wheeler 450cc engine a very powerful machine
Stock straight off the line would prolly go 60-70 mph but if tuned it can go faster easily.
every where
