Don't think your going to go wrong with any of the higher end stuff, as long as you have support here in the US.
I mainly stick to Ohlins, as their stuff works, i am familiar with setting it up and capable of rebuilding the forks, & there is LOADS OF SUPPORT for their product, on & off the track.

2 people told me the nix30 ohlins no longer exists/isnt made for these forks and one dealer says ohlins actually doesn't do them its andreani Italy that does. otherwise id have gone that route but nobody can agree on anything and I haven't seen or heard anyone on here in the usa running them.

Did you look into Ktech? I’m pretty sure they have a cart for the bike.
