Trio Knights Non Consecutive Sudoku 2013 - 1

In continuation of twisting up the Trio, I decided to take it a step further. Thought why not try it with a Knights Non-consecutive constraint. This has turned out better than yesterdays twist.

Rules of classic Sudoku apply. Cells which are at a Knights step from each other cannot contain consecutive digits. Grey cells can contain only the digits 1,2 and 3. Yellow cells can contain only the digits 4,5 and 6.
