Yes, but the difference is some extra "spoofer" plugs and the instructions to remove the charcoal canister and plumbing on the Euro4 version. If the 2017 and 2018 U.S. version does not have the Euro4 stuff, then the kit for the previous year might be the appropriate version.
From what I understand, though, RE does not make specific versions for different markets. The only exception, I think, is the dopey DOT headlight that they put on the U.S. version with the three "aiming" screws - in spite of the fact that the entire headlight bucket can be tilted!
