I Picked up the used one. The guy had 4 snow bikes and was very knowledgeable. He had all the updates done to the camso to bring it to 2019 specs, ktm forks (he said the sherco or cat ones were no good), timbersled trio, stock ski, bar heater kit off radiator, gas can, tunnel pack, maybe 30-40 hrs on bike. In his review he said the sherco 450 does not have the top end that the ktms have but pulls down low good. Also he is running the cmx ski on all 3 of his other snow bikes which consisted of a new yeti 129, new timbersled aro 129 and a new 120 cmx all on 450 ktms. He had a pile of yeti skis in the corner with a disgusted look on his face. He said hands down cmx has the ski figured out.
