2006 - 2008 is what it came off of. I don't know if it fits the '09 and up units
KA602 Model 46DR
This was put onto a bike I setup for a friend of mine as a very stock track bike.
That bike got transformed into something else and this sock is now extra.
I think it's had 3 or 4 track days on it, but hasn't been ridden in a long time so I think it should be refreshed.
These were $600 ish new.
$200 shipped to the continental US.
Others will need to be quoted
