Welcome first off.
The only way you'll know is to go sit on one and if you can find a used one take it for a spin if the selling dealer will let you.
I'm 5' 11" and ride the Wolvy more like a sport quad than a mudder utility quad so I sit further forward and there are times where I'm gently bumping my knees on the back of the front fenders. So I can see where someone taller than me could feel a little more less comfortable.
But, this is my first quad and I'm only starting my thrid full year of riding. I'm still learning different riding techniques and such so take it for what its worth I guess.
