I stopped by my dealer today to see if they were able to order the European spec front and rear signal lenses that are smoked clear with an amber bulb behind them. They were not able to order them. I got to looking at the clear lenses on the rear of a CBR1000R. They looked very similar. Out came the screw driver and sure enough they are a direct replacement for the NC. I order 2 sets. One set is available and they are back-ordered after that. I will have one set on Wed. So for those of you looking to get rid of the amber lenses here is your answer.
