Suzuki has included SCEM coating in the published features of all models of V-Strom. Many people, including me, assumed such a coating would be applied directly to the aluminum casting and figured it had to be wrong because the engines obviously have iron or steel liners. The fact is there is no reason a plasma splatter coating like SCEM or Nikasil can't be applied to a liner. Ergo, I figured the coating had to be there and was applied to the liner.
On the other hand, I just now checked Suzukicycles.com and the reference to SCEM on the DL1000 includes weight saving in the SCEM treatment which makes no sense if it was applied to a liner. A look at the features pages of the 2011, 2012 and 2013 DL650 shows the SCEM reference is gone. Knowing Suzuki has published totally wrong information before, like some torque settings in service manuals and the accessory page info that the DL650 knuckle guard kit will also fit the DL1000, I'm going back to thinking the SCEM reference is just wrong.
