New to me xtx, what ski is this?

[05rx1204]

Hello. Just bought a new to me 2010 nytro xtx. Loving it so far but looking to add snowtrackers to the skis. Looking at these skis they definitely aren't stock. They are yamaha skis and are 7 inches wide. Anyone able to identify these?

Appear to be the Yamaha powder ski available at that time.

yup, that is the old yamaha mtx ski. run them on everything they fit on as they are one of the best skis i have used to date.

i do add a 1/4" rubber shim to the back of mine to help fix the darting issue.
