V9 Suspension Thread

They work well. Had the first owner installed it there might not have been a owner #2 or #3. Next get a real set of rear shocks.

It has Matris (M18?) on the rear. I need to figure out how to adjust them because the bike is stiff in the rear. I think it was set up for someone heavier than me.

If they didn't come from me/GTM, the valving is likely overly firm. See the first post here to set the sag (critical first step), and there should be a small click adjuster top of the shock facing forward (as shown in your pic). Post another pic of the other side. If the forks are still stock, you'll want full soft (1 from full open) on the rebound. All I can be of help with.

Thanks!

I'll reread the first post. My adjusters are facing aft, and it seems like most people mount them with the piston down; does it matter?

EDIT to add: I might be missing something in the first thread. Please explain?

Maybe GTM will respond again, but that isn't an adjuster. Don't touch it. I was talking about the big nut on the bottom that needs a spanner wrench to adjust. You should have one in your tool kit. It only adjusts the spring preload. Back it off, towards the bottom 2 turns at a time or study up on "setting the sag" here. The less expensive shocks don't have rebound or dampening on them.
The fork kit should have the spring weight on the box. Make sure it's the right one for your weight. Otherwise GTM can probably get you the right springs. I'd also suggest you find an experienced man to install them.

Welcome. They are IFP. Either position works. You can see the purchase page below to show how Matris mounts them.
That IS the rebound adjuster. The blue ano w/hex on the other end is not. It’s for the gas fill. Do not touch that one. First post covers sag target. Re-read my words above.

Appreciate the help!

OK, I need the spanner wrench now. I thought I had one but if I do I must have put it somewhere where I'd be able to find it again.... I could also be thinking of the old Honda NC700 I had - pretty sure I had one for that bike.

Anyway, I didn't see one in the store, so are they of specific size?
 
Ran most of the preload out and still only getting a quarter inch of sag when I sit in it. It's still a bit rough so I'll run the nuts all way to the bottom and try that.

Morning
Has anyone got Hagon Nitros fitted to their V9?
My bike came to me with them fitted and I've struggled to dial them in for my weight.
I'm trying to work out if the PO was a short light weight individual with shocks sized to match
I'm looking for length an spring weight to start with please
Cheers👍
 
I've just realised that a fork oil change is needed on my 2017 V9 Roamer .
It's not done the mileage, but it's past the 4 years limit

I've never done this before, so am looking for a bit of guidance
I've read the manual, but the translation is a little confusing, and a search of this site hasn't helped me. Possibly because I'm not sure of the correct questions!!

So my questions to only change the oil are
1) How do I undo the top cap without mullering the surface of the "top bit" ..... sorry i don't know the correct phrase
2) Once the fork is off the bike, do I just up-end it to let the oil drain or is more disassembly needed?
3) No volume seems to be referred to in the manual. Do I just achieve the depth of 120 +/-1.5mm with the spring out.
Manual also says " with stem at end of stroke"
Does this mean fully compressed?

Also.
Specification is for 7.5 weight oil.
Is that OK for 14 stone 4 lb (200lb) in all my gear

Cheers and apologies for the clumsy wording.

Tris
 
You might have a plastic, black decorative cap on the top.
You need to get the proper socket. Might be a 28 or 32. I don't remember. Get a 1/2" drive.
You can do them one at a time with a jack if you don't have a center stand. You will need to loosen the clamping bolts, slide the fork up, then tighten one down to unscrew the cap. Turning the fork upside down works best, and working them to get it all out. Same with putting oil in. Much simpler if on a center stand so they can be collapsed together or better yet while still off the bike. I used a small carpenters square to take the measurement. I use 71/2 if the roads are bad and 10-15 if good.
 
Have you been in contact with Hagon to see if they can have the shock back so that it can be set up with you and your weight / pillion / luggage specifically in mind?
 
I have and they confirmed that I had the correct weight spring for me.

However I took a brave pill and wound on a couple of extra turns of preload and this seems to have sorted it out.
 
I emailed Sales@GTM….and got no response so maybe someone here knows the answer. At the beginning of this thread it is stated that stock KYBs are 347mm long. I’m assuming that is measured center of the eye to center of the eye. My Roamer measures 370mm. In GTM 2WS shock’s stock configuration what is that measurement? Assuming the 370mm measurement if I choose the -20mm length option how much lower will the rear of my bike sit?
Anyone lowered theirs? Any gotchas to be aware of?

What year is your V9? Courtesy of Google... The original shock absorbers for the Moto Guzzi V9 are 360 mm long. You have stock shocks? Post a photo.
~20 mm shorter shocks lower the seat around ~1" total. It is well covered on this Forum HERE.

My 2017 Roamer with stock factory supplied KYB shocks measure 370 eye to eye (center). I would not ask here unless I was exploring purchasing through you. I wasn’t DEMANDING anything. I just want information to make a proper choice. Wow! Delete away.

Very good, AS STATED, NOT AT YOU.
Many people write us demanding answers to their questions, again, as noted above.
It helps to state "Looking to purchase from you..." somewhere in the email.
