GNCC type suspension companies - Recommendation Needed

Factory Connection. Great customer service, if they don't get it right the first time, they will work with you to get it where it needs to be.

I always have great luck with Motoworx. Rob and Brian are great folks to work with and have a ton of experience.

GTR suspension. Awesome with ktm woods suspension. He is an A level racer who still rides a few times a week and really knows his stuff. He's located in central ct.

His name is Gilles Trepanier

I would go with someone semi-local that you can develop a good rep with. Sometimes it is easier to drive a little and get the service done than deal with shipping if you're ever in a pinch. Shipping times are usually shorter and cheaper too.

Chad Newton at Total Control in Burlington, NC
HDR (Heavy Duty Racing) in Stafford, VA
Full Travel Innovations in Thomasville, NC
MotoVations in Hickory, NC

All 4 shops have done suspension work on bikes that either I or my regular circle of riding buddies/fellow racers have used. All work IMO is comparable. Chad at Total Control did my bike simply because he is 40 minutes from my house and I was able to swing by and shoot the shit with him and go over what I needed in depth.
