6.yamaha yfz 450
7.yamaha grizzly 700

i want something that i can go mudding with but also has some speed and can trade in for a faster bike like a outlaw but i wanna have something that can go fast a can go through mud also

 

You have a mixed list of top of the line sport quads, and utilities. That doesn't make even one bit of sense. If you are a mudder, I think you are (sucks for you!) stuck with a utility!

Of you list, the only ute I would even consider for half a second would be the Griz (last on your list).

 

If you mud you want 4wd and lots of ground clearance,
1.polaris scrambler <u>4wd but only 6" gc, no low range</u>
2.polaris sportsman 800 <u>4wd and lots of gc</u>
3.polaris predator 525 s <u>only 2wd</u>
4.can am renagade 800 <u>fast, 4wd and lots of gc</u>
5.yamaha raptor 700
6.yamaha yfz 450 <u>2wd and not much gc</u>
7.yamaha grizzly 700 <u>4wd and lots of gc</u>

probably the Renegade will suit you best! fastest! most expensive$$$
If you want lots of storage and racks then the Sportsman or Grizzly.
Sporty looking and 4wd and cheap the Scrambler!
