That is the R obviously, but still quite amazing! How suited is this for enduro?
What is the dry weight of a X?
My thoughts exactly 
Hilton Hayward suspension + flywheel weight + recluse is what I believe will sort it out.
250x is a no go for me: it's 12kg's heavier and costs quite a bit more 2nd hand. You can have an enduro prepped R for less than a 250x it seems
You have obviously never ridden a MX bike in an enduro. It does not matter what you do to the suspension it remains a MX bike due to frame geometry.
In Cape Town the majority of riding is done in soft sand which kills 250 4t's
I wonder how those guys on the WR converted YZ250's manage to stay competitive in enduro races?
If memory serves, Gray Dick was SA enduro champ on a YZ426. Jade Gudzeit was enduro champ on a YZ450F. Mahoney raced a YZ450F in the enduro class too.
And then there is the 2012 Roof winner on a YZ250F.

Their MX frames must have been replaced with KTM enduro steel frames... cant be the suspension!
As for thick sand, the 250 2T is not the right tool either. Even my 300 didn't come close to a 450 in thick sand.
KX250's bottom end left much to be desired as an RM would too. I'm sure you love your RM and yes RC won many SX titles on one but that was then and this is now. The 250 2T's would not clear many of the SX jumps in the AMA championship any more. They simply lack the grip and bottom/mid range, which is what I'm looking for
