Poo's accessories site suxs for compatibilities - there's been some updates, but some are still missing. Their engineers just didn't seem to have the time to differentiate the Matryx trail bars and new switch console from RMK/Pro Taper bars/console, so they skipped most/all of the compatibility. Will get better this year.
The issue with many Axys bar bags is the collision with the relocated Matryx switch console - not as much of an issue with any of the RMK Pro Taper bars. I've not seen a collision with the 7S on any Poo pro taper bar bags. I ran an Axys pro taper bar bag they no longer offer that is similar to the 2882823 that they market now - just deeper, and with no front bag. Works perfectly with the 7S. No rub with the switch console, but you do need some muscle memory, since the switches cannot really be seen with the low Pro Tapers. There is lots of room for a front bag on any Matryx RMK sled - both visually and without collision with the 7S. With Skinz out of the game, the options are more limited. Didn't both Adams and Burandt run these Skinz bags with both front and rear compartments on their Matryxs?
