The SV105 is the 2015 USDM release of the Alphas SV.  The reel shares many of the same features but differs slighty.  The reel weighs .2oz more, features 2 more bearings which are CRBB, and has different frame porting.  The biggest difference is the lack of a left handed power model.  The reel features the same color coding system, silver for the power speed, red for the hyper speed.
