Ah I am going to get a new bike soon and cant really decide which one to get, how much speed difference between the 2? And I ride a lot of trails with my friends who all have 4x4 but they rarely ever go through mud so is extra power on the kfx worth losing 4x4 for?

 

If you're never going to use 4 wheel drive, and don't need the rack space I would def. get the kfx, but if you're s.o.l if you need to do any type of work w/ it

 

Since your friends all have 4x4, I'd say go with the BF so you guys can ride the same type of terrain. I'm sure there will be times you'll need 4x4.
Plus - you live in WV - you never know when the group will take a ride to Hatfield McCoy. I haven't been there, but it sounds like 4x2 quads don't stand a chance there.
