    Question Michael, curious if the top and bottom mounts completely clear the frame? This has been a problem on some of the multi-fit application shocks.

    Unrelated/related: Since Prog Susp is local to me, with a scheduled appointment, I stopped in a few years ago with a handful of twin shocks from various models. They gave me a tour, and told me how I could assemble shocks from their parts list, uninterested in anything I brought. They are focused on where the $ is (HD, rightfully so), and the few models that their owner or staff is interested in. I left really disappointed. Parts Unltd is a distributor only, not retail.

    I anyone wants to throw money at trying them (stepped spring preload adjuster only dirt bike shocks, with heavy duty springs for riders over 200 lbs is the spec stated above) for $255/set, I can get them as parts to assemble from my distributor, and can put them on the online Store. Post below or best to email me direct; Info at GuzziTech.com

    On a side note and posted above already, I recently added a nicely made purpose built-to-order (length also) twin shock line for $399; https://gtmotocycles.com/collections/suspension/products/gtm-s2w-ifp-twin-shocks

    I saw an article somewhere on here that dropping your forks was a good thing to do, well tried it at the weekend and the difference is massive. The handling of my V7iii Carbon was okay but didn't inspire that much confidence (could be the standard tyres) but after lowering by 15mm, amazing.

    Only six screws and away you go; so if you're only ever going to do 1 thing to your V7, do this, you won't regret it (and it doesn't cost a thing? :) Before and after below.

    I kept the relationship with the headlight the same as there's not a massive clearance between the clutch cable and the speedo and I didn't want to cut some new spacers, but I might have to make some for the top now...

    I dropped mine about 12mm but haven't ridden it since.

    I'd like to do the same to my 2013 Special, is the frame geometry the same as the 17?

    Hi, Todd just seeing your question from a few months ago. I have no clearance issues with these shocks. I saw quite a few V7s in Seattle with this setup, presumably because Moto I was recommending and installing them.

    Disappointing to hear your experience with Progressive! Michael

    The Progressive shock I installed in my Victory sure doesn't ride like an offroad shock, it's great.
    Totally different though- monoshock amidships, on a much heavier and more powerful bike. Its from the 485 series.

    Hey Todd,

    I purchased a Matris fork cartridge kit from you around 2/24/2018. It took forever for me to install because life intervened and I moved from Falls Church, Virginia, to the Asheville, North Carolina area. Since the move in 2018, I've had very little time to ride and now that I've managed to get some miles in, I've discovered the bottom screw - the damper securing screw, the one that holds the cartridge in place in the slider and that you have to remove the front axel to reach - has loosened up and is leaking. When I originally took the OEM fork internals out I found the screw to be incredibly tight. I had to use a breaker bar to take the screw out. I guess when I reassembled I was worried about stripping the alloy Matris so I reckon I didn't tighten it enough.

    Questions - Do you have a suggested torque value for the 8 mm screw that fixes the Matris cartridge to the slider? Should I use a crush washer?

    My sig was MRLost back then but I had to change ISPs when I moved so I've changed my login.

    Thanks mucho.

    Th parts and service manuals give no hint about the recommended torque. When I installed a Matris cartridge set on my V7II, I used a rattle gun to tighten these screws, because the cartridges rotated when I tried tightening the screws with a torque wrench. I couldn't find a way to prevent the cartridges from rotating, hence the advantage of a rattle gun. I was aiming for 50 Nm but it probably ended up with more torque. I also used new copper crush washers. No leaks or loosening over the next 2+ years and 13,000 mi. Hope this helps.

    Guys, this isn’t my Inbox... I don’t catch every post here, and I hover around 1000 emails/day, so be patient on a reply. At some point soon, I am not going to be able reply to questions here outside of Ask the Wrench sections or direct email.
    I don’t have a torque value, but I’ll ask Matris. I also use an impact like sib, as I’ve done on every set of forks since I was a kid racing.

    Email me on any login issues; Todd at GuzziTech.com

    Thanks sib - that's just what I needed to know. 50 Nm is a fairly high so I won't sweat running up the torque level. If I encounter the issue you mention - that the cartridge spins with the screw as the torque level rises - I can buy an air impact wrench. Always have wanted an excuse to buy an air wrench.

    No prob Todd ... sib provided the info I needed.

    I've merged your post with this thread. Start from the beginning and skim down. You will find your answer most likely... then click on the Store tab above for our selections. For tight budgets, and depending on what you weigh, fork springs and our GTM S2W option; https://gtmotocycles.com/products/gtm-s2w-ifp-twin-shocks

    I purchased the GT V7 "Hybrid" Fork Kit with the Mupo emulators, Matris preload adjusters and RT springs and the RT IFP Twin shocks for my Stornello last year and here are my thoughts on the installation and riding. I'm 220 pounds and ride a Stornello.

    The easy one is to talk about the shocks. The OEM shocks were quickly replaced with the Progressive shocks at I Moto's suggestion but the improvement was slight and I was looking for a bit more height. Todd suggested the RT IFP with an extra 20 mm. Installation was straight forward and the improvement significant. The higher rear end meant that the geometry changed slightly and the bike turns in quicker. That is handy both on the street and the trail and I think was an improvement. No regrets! For the light dual-sport riding I do on the Stornello (no jumps!) means that I like the damping on the light side and I progressively dialed it all the way off over a couple months of riding.

    The fork kit was selected as the OEM damping rod system created a harsh response at high compression rates; exactly what my commute on the freeway was giving me and in off pavement riding ! had to keep the speed way down to avoid sharp responses. The harshness was bad enough I decided I couldn't tour until I fixed it. Todd suggested the Hybrid Forks kit which included the Mupo emulators and Matris preload adjusters and RT springs and spacers. However, the damping seemed to increase. After reading up on how emulators work and what others did, and recognizing that I don't have the tools to take apart the forks, I took the forks out of the bike and headed over to Hamlin Cycles. I emailed Mupo for instructions without success, but as RT has a similar looking emulator Jim decided to follow the instructions for that. Although the emulators are described as drop in, we were looking for less damping so he drilled out the damping rod holes to 5/16 and added another pair of holes. We put the Mupo emulators in with the acorn nut up as that was the way shown in a Mupo ad. After reassembling the forks he poured in 15w fork oil and set the air gap at 140 mm. I raced home, reinstalled the forks and headed down the street. What a huge improvement!

    Now, two weeks later and after a couple others have ridden the bike I'm thinking it might still be a bit too much damping. The bike is still firmly planted in turns but the high speed compression is a bit hard. I will try increasing the air gap and may go to 10w fork oil when I change it this winter. I'm off for a two-week trip to Gaspe and it will get a good workout.

    Update: July 2020. The Gaspe trip was great with a mix of paved and unpaved roads, a few km of trails, snow, sunshine and heavy rain. To the point of this post, some of the roads were rough and the Stornello's revised suspension was, to my taste, still too rough on compression, although much improved. When I got home I syphoned out as much of the 15w fork oil as I could and replaced it with some 7.5 I had lying around. A small but noticeable improvement. A couple weeks ago I decided it was time to change out the fork oil and I replaced it with 5w and set the airgap at 160 mm, still more improvement, although the front end feels more small movements, probably due to the lower viscosity reducing the rebound damping.

    I think this is about as far as I can go, other than increasing the air gap a bit more. It works pretty well and is a huge improvement over stock. In hindsight, I should have figured that the non-adjustable Mupo's were designed for street riding and I'm looking for a dual-sport setup with softer damping. The Race Tech emulators with their adjustable damping would probably have been a better choice for me as I could have dialed off some damping.

    One day after I replaced the fork oil I did hear back from Mupo with instructions. Luckily my guesses were basically correct, although for the V7II they recommend 10w and 135 mm.

    Here's a pic of my V7 Mk III with a pair of Hagons. 3 pre-load settings, 9 damping control adjustments. Different bike. It's on rails. No po-going, no spine compression. Bliss. New tyres too. Metzler Klassics: So far-so wonderful.

    Hi, I'm looking to lower the rear on my v7 11 2016. I don't seem to be able to find out what length the standard shocks are and to what extent I can safely lower the bike without causing excessive stress to the transmission.

    The rare suspension is pretty harsh over bumps, which way do you adjust the lower adjustment ring on the shock to soften the ride, up or down?

    Thanks

    Attempting to install a Matris kit today on my '13 with Kaifa forks... I noticed that the bushing and oil regulator do not seat into the stock springs... it looks like it's intended to though, can anyone confirm?
