Title: Matris F15k Cartridges - V7 850
Post by: YellowDuck on April 27, 2026, 08:13:11 AM
No question, just wanted to share my happiness with these fork cartridges.

I installed them over the winter (very straightforward job for someone who has any experience at all taking forks apart - no machining needed), and just recently got the weather needed to go try them out here in SW Ontario.

Mine came with 7 N/mm springs, and the forks are very compliant.  Matris's suggested preload setting gave me sag of exactly 1/3 of travel (so, they did the math right).  I also started with the suggested damper settings, and they were immediately such a clear improvement over the OEM forks!  I have fiddled with rebound quite a bit since, but am finding I like the suggested setting as much as any other, on the pretty rough roads I ride.  I always find compression harder to tune, but I will eventually monkey with that as well.

Honestly, the forks are so good now, it makes my rear suspension with Shock Factory 2Win shocks seem a bit basic.  Nothing against the 2Wins, I think they are great, but there is only so much you can hope for with a twin shock, linkage-less setup.  I had the same experience with YSS fully adjustables on my RE Interceptor - it's never going to be great with that geometry.

But the forks...if they were any better, I doubt I could tell the difference!

I was really focused on what my suspension upgrades could do for me on crappy, broken asphalt - mostly, reducing the harshness of the compression damping over sharp bumps, and the lack of control over extended bumpy sections.

The changes have improved both of those things, but as I ride the bike more, I am realizing that the benefits on relatively good asphalt are even greater.  On smooth pavement with lots of corners (like, switching from a medium speed left immediately into a medium speed right), the improvement over the stock setup is incredible.  Feels more or less like a sport bike. It's really a remarkable difference over the stock setup for that kind of spirited riding.

I take deliver of my V85 Strada next Friday.  I guess we will be back at square one on getting the suspension sorted on yet another bike.  Might wait a bit to start that project.  I already bought the MG Urban panniers (and associated hardware) for it, so $$'s getting a little tight!

A tip, set the new v85 up exactly as the owners book states. From there never go more than 1 turn or two clicks. They make a big difference. I raised my forks up 4 lines instead of the 1 it recommends but mostly because I'm short.

Is there a guide or manual I can use to set up my Matris cartridges? A previous owner installed and I love to tinker, but am ignorant.

A sheet would have come in the box with the recommended settings.  FWIW mine said 15 clicks rebound, 15 clicks compression, 6 turns preload, 130 mm air gap.

I've said what you have for over 15 years.  One need not be trying to qualify for Superbike to enjoy the benefits of proper suspension.  The results of a job done correctly are superlative and make a huge difference in everyday riding.

Thanks for that V, I'll have to pull out the owners manual and try to figure out where my suspension "should" be.  I got my v85 used and haven't messed with the suspension and don't know if the PO did either.

I had considered these, instead it went the cheaper route. Hyperpro springs and raised the fork tubes a 1/2".   For the most part its a good set up, but the Matris probably better with all is adjustability.
