2012 600 RMK Differences

[xcr800man]

Thinking about buying a new 600 RMK for a spare sled and for my kid to ride. I am wondering about the cooling system primarily. I know that the 155" 600's have the coil over suspension both Pro and Standard. The 144 uses a standard torsion spring like the Assault 144 switchback skid. I also know there are differences in the shocks, but the cooling is what i am most concerned with.

Do BOTH of the standard 600 RMKs both 144 and 155 have the additional cooler? I see nothing in the literature. I would love the PRO 155, but it simply isnt worth the additional money especially if the Pro is missing some cooling capacity in my application.

So what is it on the additional cooler???

Thanks in advance!

The 144 600 RMK as well as the non-Pro 155's all have the additional heat exchanger mounted to the front of the tunnel. So far 400 miles, no cooling issues. I set the scratchers down for hard snow conditions. This sled is the real deal and should be considered better than a second rate deal, back up, or for those with minimal experiance. The 2012 600 RMK engine can get the uninitiated into trouble quickly.

We had to rent one in our group on our last trip and it was a 600 144. was actually very surprised by how capable this sled was. I think the lightweight and solid chassis lend it self very well to the 600 motor. we were in the big horns at around 9k elevation. I think over 10k though it might be a little doggy. But under that its got plenty of power and float.
