You brought up some interesting topics that I need to think about. The price for the Matris is really hard to beat.I looked into it myself. They are definitely prices right. But I went with a well know/used brand because I know there are people that have proven success with them. I could only find a few people that carried matris fork cartridges or even had them. When shopping for fork parts keep in mind who is going to do the work. Are you going to do it yourself or have them installed? Also does the person doing the work have experience with your product and can they help with setup and service. I would say look into Traxxion AK-20s. They are a little more but there are tons of people that have them and easy to find help for. Contact Superbike Supply as them gave me a great price when I was looking for them.
i think that with the way suspension technology has advanced, we cant go wrong with any of the after market suspension brands....be it Ohlins, WP, Matris, Showa etc...nice to hear that somebody is willing to test these out
