Whats the difference? Is there any?

 

pretty much just different colors

 

According to the idiot dealer here in town, "the Z has a little more torque and a little more horse power" At the time I was buying my KFX. The dealer was out of them but they had a ton of Z's laying around. The freakin jerk was trying to make a sale! What if I hadn't known the difference? I would have ended up with something I didn't want. Dealers Suck! Sorry, just venting.

To answer your question, scrambler420 is right, only color and the black cowl on the KFX.

 

that sucks, I hate salesmen

 

The green one has a little wing over the headlight. The headlight on the yellow and white ones glares off my goggles.

EVERYTHING else is the same.

 

plastic and headlights, thats it

 

you like green or yellow better???
