No they dont fit a axys. I tried already and would have kept it.
The rear post are about 4" to short. Thought about putting longer rear seat post on it but then the bag wont hit the tunnel.
The axys gas tanks are taller in the rear than a pro.
Honestly I dont know if you can get a seat that is more than 1" shorter than the one they put on the sled from the stock seat with the gas tank configuration.
