I would figure the DL and the GSXR could easily be certified under the GW 'umbrella' no matter the market they are in. In the U.S., once a bike is certified, it lists several models that fall under the certification. There would not be any issue with these two bikes to be certified in the US provided they are based on the GW 250. Suzuki should take away the word 'concept' and introduce it worldwide to what I believe would be a receptive audience--certainly more receptive than the GW 250!
