Has anyone been able to draw an conclusion about any of this on the KFX?

GNCC fronts vs Razr2 fronts?

Have you tried both on the KFX or past experience?

Forward vs Backwards

Have you tried both on the KFX or past experience?
Please indicate which tire or both...

What about 21" fronts vs 22" fronts?
Some folks seem to have an opinion on this too.

I did a bunch of image searching and came up with this picture of the Razr2...
And I think I see a directional arrow there...

And that is the direction I am referring to as "backwards"....

Yeah guys... I have to run my GNCC's as I have them pictured HERE... looking backwards

They ran well for me opposite of shown above in the mud... but I started feeling something I didn't like as conditions started to dry... and I was just trying to make sure I wasn't nutz...

I ran them opposite of above one too many times... just tooling around once more right before changing them back... And I figured out for sure I was for sure feeling what I thought seemed to be coming on... catching late and hard...

It was dry enough to 2-wheel me in an off-camber corner at little speed.
Skinned my elbow and knee good saving the quad from rolling over.

Lesson learned on my first set of fronts with angled side knobs.
Looking backwards = opposite proper tread pattern in ground contact...

I butchered this Can-Am pic to illustrate....................... (flipped this side tire around)
And angled them as turning

It's pretty easy to see this way why they don't track well the other way.............. (this side)
And why they hook late and hard ran the wrong way.
