Hey, honestly, which one would you get? The x4 or the x4r. I have money for either the x4r with the stock gpx or the sgr edition x4. If i got the x4r i could always upgrade the engine later, maybe.... if my dad will let me. But, is it that big of a difference or what. I like the zocchies on the x4r but the sgr x4 motor. Do the forks even compare, and would the regular x4 forks handle huge stuff?
