If your DL650A is an L4, it is, by definition, a 2014 model year bike. A means w/ABS and L4 means 2014. The service schedule changed on the 2015 model year on the L5. The schedule changed due to a corporate decision, not because of changes to the bike. If you want to service the bike to keep it in good condition, you can use the longer interval schedule. If you need to service the bike to support a warranty, you need to use the shorter interval schedule because Suzuki are not supporting a change until 2015/L5 models.
