Teninospyder, the VIN sticker on the left side of your Spyder's swing arm should have the manufacture date, MM/YYYY, on the top line in the right corner of the sticker. Your OP piqued my curiosity and I looked to verify that the mfg date on mine is 03/2014 and on the BRP safety recall lookup box results it shows mine listed as an RT S 1330 ACE SE6 C 14. If yours was manufactured earlier than 03/2014 it could be because in the history of the RTs the ACE engine was originally scheduled to be introduced in MY '13 but it was not quite ready and that's why the '13 RTs have the V-twin SE5 engine. If the mfg date of your Spyder is later than 03/14 I guess one has to chalk it up to horrible BRP manufacturing records.
