Bigger idler wheel on 2011 Assault 155"

Not many people have had time to get ahold of the sleds to build parts. BUT, i would think that it is the same as the 2010 sleds. It does have a new rear suspension but why would the change the wheels. On a side note, i don't see why you would ned bigger wheels unless you are going for hte bling factor. Imo they aren't worht it because of durability issues, and if one goes out when you are riding, who knows if the local shops will have hte corect wheele/bearings...
