Are the dimensions of the rear shock on both the 1100 and 1200 the same? Just want to fit a shocktube and have seen one advertised for an 1100.

Same unit I believe.

just gets interesting when you put an ohins from ans rsv mille in. They are not expensive used. Only have to look for right version, because there are a few different types, they changed the link ratio somewhere. I know someone who did it.

For a shock sock it will not matter, you need a 7" minimum or an 8" better, the 8 will have just a little room.

Heres how to measure for the R&G offering, but as previous posters have mentioned the standard units are the same on all [You must be registered and logged in to see this link.]

I would try this site, get in touch with them, they seem to be the manufacturer. They should be able to point you in the direction of a distributor.

Traxxion Dynamics has been selling socks for years, these eliminate leakers from the seal head about 99% I have never had a covered shock leak at the shaft.  now there is one issue with all carc bikes nothing over 84mm  od will pass through the swing arm clearence hole without rubbing. this is a big issue with aftermarket shocks and re-springing.  use Ohlins springs only on the stock sachs 1091 or 1093 series and up to 1100lb rates they will fit through the swing arm

built right the stock sachs with the right valving and spring will match any twin adjustable shock on the mkt.

Anyone happen to know the shock length eye to eye, and stroke?

the stock stroke length is goofy short at 23mm, (this is measured from the body to the top of the bump stop at full ext.)  You can extend this safely and comfortably to ~28-33mm.  which raises the rear end just over 1"  The key is you have to keep the top of the bump stop in the same place as on the stocker.  so In My case I like to take Gsxr '09 1k shocks that are the correct 5-7mm longer than the stock GRiSO shock, but have a stroke length that is 3x the GRiSO and limit their stroke with the external bump stop.  That short stroke length really hurts the shocks ability to control the rear end.   Working on a good link to alter the rate curve... but that may take a while to run the fea and test.  The stock sachs I have in front of me is 320mm (without spring) 321mm with spring, and a stelvio is 328-334mm (measured a few and there is a variation).  the stelvio matris shock drops right in the GRiSO and gives more stroke and about 1-1.2 " lift to the rear of the GRiSO.  I did not check to see if it topped out in the correct spot or not.   The extra stroke comes from a longer shaft and shorter body combo, with bump stop to match.  The penske vdp, or regressive / linear piston seem to be a good match for the linkage in these bikes.  Without being able to as of yet modify the linkage a progressive wound spring would be a good bandaid like the old elf swingarm hondas had but there is nothing close I have found yet.  Swift made noise like they would wind me some samples but I have not come up with numbers for them yet

ps 1091 ohlins springs will probably need a spacer for the stock sachs body, the 1093 do not these work well as they keep the id consistant, unlike hypercoil that drift fat on the id and thus then on the od at rates over 750lb. these both fit showa, kyb, and penske bodies as well as the stock sachs. You can pull a head off a double adj sachs and screw it on to the body of the stocker and have high and low speed compression if you want. The Penske is probably the most versatile option for the Crowd...it offers a range of tune ability that is able to get the feel you want, stroke you want etc. by picking parts no other maker is as open to selling you guts to make up what you need. The factory valving works ok for a spring of about 750lbs. which is ok for a 170-190lb ish rider (800lb is better). that kind of tells you how bad it was for the whimpy 485lb stock spring. Most folks running the rebound at 30-40 clicks out means it was doing about nothing. and with the low speed set at the usual1/2 turn open it is doing way too much. If you ride 2 up much go for a 850-950lb spring. The match for this in the forks is about 1.2kg/mm

@ Uzidzit:

Totally intrigued by the notion of raising the rear ride height. Always felt like I'm following the front wheel around on the GRiSO and it essentially causes me to ride with my jewels hard up against the tank all the time.

Would you kindly post some annotated pics or something like that for the bump stop mods on the Matris Stelvio shock and home-brew GSXR shock. Xtra stroke and raised ride height would seem to be a win-win scenario.

Thanks!

Will do some pics of the Penske install tomorrow evening I just did the cannister bracket, no more riding around with it zip tied to the passenger peg,  cheers  probably take at least a year to actually finish the bracket though, as my priority is getting youse guys some bar raisers done first...it is actually very easy to do the long stroke shock. getting the fully extended length right is the trick, after that limiting the compression stroke is easy peasy will show in pic
