I was planning on ordering the T-Motion kit and flex track for my 2012 after riding the Demo model last season. I was also considering ordering the bar controls as they suck on the 12. I made a last minute decision to upgrade my 12 to the 13 considering the marginal price difference after the upgrades and after the first ride on the 13 last weekend in 4-5 feet of blow over the head pow, I do not regret my decision one bit.
I have to say that the 2013 XM is the best "out of the box" sled I have ever ridden. All I did was put on a can, skid plate and scratchers and it is a dream machine for handling. My 12 was a 163X and my 13 is a 163X and the difference is incredible.
I got on 2009 XP last weekend while I let my buddy ride my 13 and couldn't even ride it.
Stoked!!! Can't wait to shred on the 13 154X!!
