I have X-Fusion Enix 120mm on one of my bikes. It is their “Value” fork. For a $120 fork it feels amazing. It does not feel as good as Fox, but comes very close to some of my Marzocchi forks for much less $.
There is no over the counter service kits for these forks, so you have to call X-Fusion for one or send the fork in for service.
I have an X-Fusion on one of my spare bike and i have had no issues. From what i have read they are even getting better as they now are the only ones to have a one piece crown.
But i will say it is not as smooth as my Fox' forks or shocks.
