| OK. Thanks. So your rear spring looks to be a 110Nm. I’m 75kgs (closer to 85kgs in full gear) and mine came with a 95Nm rear spring (listed on my card as 95-130). | |

| Interesting.
I assume that "Rider Sag - 40mm" is for the fork? That seems like a lot. And the zero on the rebound seems a bit odd too.
For the rear, no Rider Sag number there? Just the static sag of 8mm. | |

| [You must be registered and logged in to see this image.]Hopefully have now worke dout how to upload a photo! All works very well for me, way way smoother ride if a tad on teh firm side but I guess thats better than saggy. I am on bumpy single lane local roads much of the time........

| Interesting observation re: the firmness. Assume that you may be talking about the rear (Wilbers)? I've had a similar experience. The valving on the Wilbers seems significantly better than the stock unit, and the ride generally reflects that. It still feels a bit firm on the sharp bumps though. However, I'm hesitant in turning down the high speed damping too much noting the very limited shock travel. | |

| Firm but not uncomfortably so, I guess seems more set up as a 'sporty' ride than a cruiser. I haven't changed a thing since the Wilbers was fitted and set up as the difference when I rode out of the suspension specialist was night and day improvement over the Matris. I guess I could make further adjustment but I am very happy where it is, feels superb on fast flowing smooth roads, just a bit firm on the bumpy old single lane roads around home. Suspension man was not complimentary about Matris and in fact would not work on one. I know that folks in this parish seem positive about Matris and perhaps I made an error buying the regular Matris shock (I think it was a no.46 or something) and instead should have gone for the R model with the hi and lo speed damping etc., but that would have been north of £1200 in the UK, the Matris I bought was I think £770 and the Wilbers about £900. All very expensive options but my GRiSO is my go to 'all rounder' bike so I thought worth investing in the suspension. I am now very pleased with the results but would not buy Matris ever again! | |

| I got Matris front fork cartridges not long after I had the Wilbers rear shock put in. Same suspension shop did both jobs. Appears that there wasn’t a Wilbers option for the front forks at the time. Anyway, the Matris front is good, albeit took a while to bed down. It is pretty good though. Heard that the Matris rear isn’t so good, as they come with a 135Nm spring whether you’re a 50kg legless midget or a 140kg man mountain. That can’t be good. | |

| Yes my 100kgs had the same spring as another forum member at 75kgs. Bit of a mis-description as Matris are advertised and marketed over here as 'bespoke' built to each order and rider size etc. At least the importer was fair and refunded me. I have K-tech springs and forks were stripped and re-assembled with fresh oil etc by suspension man. Feel very good, possibly a tad firm and suspension man said I could go down to 0.9 springs but I was worried about bottoming out - when I originally fitted the 0.95 springs I seemed to have very little travel left after an 'emergency' stop, although now he has fettled the forks they feel far more compliant and seem to have less travel (go figure) so I could probably get away with 0.9 without bottoming. GRiSO is no lightweight track special so I am at the point of just living with what I have got as it is really excellent across pretty much all road conditions. | |

| But ... you have a high speed compression clicker to play with! I would suggest ... find a section of road with the sharp jolt bumps ... ride over them 4-5 times with the stock Wilbers settings. Then turn 2 clicks softer (out) on your high speed comp, ride through the bumps 4-5 times. Any difference? Then go 2 more clicks softer on high speed comp, ride section again. I would keep going until you get it better and then it doesn't get better. So say at 6 clicks out you have an "ah ha" moment where it works much better, but 8 clicks and 10 clicks are no better. Then go with 6 clicks out (so, 6 additional clicks out, a total of 20 clicks out at that point). Then try it out on a road with dips and ups and downs and see if the rear is moving around too much (so a low speed comp test) (high speed comp will affect low speed comp). You might try going two clicks in (stiffer) on the low speed comp if you notice too much movement. And at any point you go just go back to the original settings, so nothing to mess up really. | |

| And that 40 mm of fork sag is bothering me too. I'd be very tempted to tighten up the fork preload to around 30 mm (many guys run 20mm-25mm, or 25mm-30mm). Sounds like you have a suspension person that did all this? Check with him maybe? I'd rather run 30mm sag and if the bike was too "lazy" turning in I would leave the pre-load at 30mm and raise the fork tubes up a few mm. You need the sag to keep the fork in a "good place" for working well ... you should not run way too much sag to change the chassis dynamics (lowering the front for quicker turning). Again, this is all free and easy to try out. | |

| Thanks 'usedtobefast'. Just back from a weekend blast to le mans with my son on his first 'big bike' a Kawasaki Versys 650. On smooth French D roads (amazing how much better their surface is than the rumble strip we have for roads in the UK) the GRiSO is pretty much faultless. On our UK rumble strip it then feels a tad firm but compliant - as I think I said earlier, a 'sporty' ride. In my view its all a compromise depending on what you spend most of your time riding on. I'll have a play with the Wilbers damping and see if a bit of fine tuning really optimises it. Lovely ride though down and back on the French D roads, very little traffic, excellent road surface and rolling along at between 60 - 90 mph GRiSO felt superb! So I think the suspension is in a good place and maybe some minor tweaking will make it even better. | |
