The most obvious is the upgrade fork, RockShox Recon instead of Tora, followed by a full Easton wheelset. The 2011 also features a full SRAM drivetrain, mostly X7, with an X9 rear derailleur, instead of the 2010's Shimano mix. There are also Avid Elixir 5 hydraulic brakes instead of Shimano. Because of these significant differences, the price point is several hundred dollars higher than both the 2010 version of the Big Kahuna, and the 2011 standard Kahuna.
