Though not formally listed as being compatible, this bag fit PERFECTLY my 2012 Z1. The ports and hoses matched the bag exactly so installation could not be any simpler. Unclip the four existing lines, pull the old bag, position the new one and reconnect. That easy!
I do have any issue with water being siphoned out - the bag loses about 25% of its capacity under a 7 degree list. This is an issue well described on various forums and not endemic to Tige or this bag. There is plenty of information out there on how to correct.
Regardless, the ease of install and the immediate increase in ballast load has produced an amazing wake which I couldn't be happier with. I'm just sorry I didn't do it earlier in the season.
