Bought myself a Stelvio shock to increase travel and comfort for both myself and her indoors, might also try some 1inch extended footrests.
It's funny first few times rode the GRiSO never noticed the bumps though did notice the ride was a bit on the harsh side.
Too busy buzzing enjoying the bike to notice.
Last time out with the missus we both noticed the potholes and rough roads big time.
Buying the Stelvio shock was just the excuse I needed to service the swing arm bearings, especially after discovering the Pivot Block Bush & Bolt Head on the swing arm was seized in two places.
Ended up replacing a slowly becoming f*cked shaft drive UJ (unknown to me prior)
Fit seals to the gearchange linkage ball joints.
Do Petes 290 loctite fix on the bevel box.
I guess you could do the grease job in around 3 hours but the rest takes some doing if your impatient.
Aquiring the shock takes some patience as they don't come up too often, if they do they are scruffy as and expensive, that and have import duty fees.
£250 inc duty, vat, shipping and a new spring is pretty expensive these days compared to a basic monoshock from Hagon.
Am thinking maybe should have probably gone that way
Looking at £330 delivered though possibly £400 for my weight plus a pillion.
Could cost you another £40 for spring compressors for the Stelvio or pay someone £20 to remove and replace the spring for you.
There's a few vids on youtube using cheap amazon rachet straps.
Watched a few idiots but you get the idea.

My purchased Stelvio Shock with softer 9kg spring[You must be registered and logged in to see this image.]
Removed spring with Ratchet Straps and cleaned shock some.[You must be registered and logged in to see this image.]
Fitted a new 12kg spring, 2.25 inch internal diameter and 7 inch long -(am 6ft 2inch 17 stone 107 kilos, Yellow spring on later NTX model is 11.09kg good for 15 stone riders)- to tidied shock plus stuff you will need. Rags to protect new spring from ratchets, a screwdriver to un-lock the ratchets-
gloves to protect your hands. Get more use of those two cheap straps than new £40 spring compressors.[You must be registered and logged in to see this image.]
Aint nothing sexy about the Stelvio shock, it sure is some fugly plain looking item.
Cheap and Practical, heard good things about Sachs valving in these shocks.
You can have some fancy expensive shock don't mean its going to perform any better than the original.
The difference in length of the shock is marginally not a lot 25mm, its a combination of slightly longer shock and reduced length of hydraulic body giving more travel.
Stelvio shock only has compression via the big knob which is a damn sight easier than the GRiSO shock's lock rings, and Rebound via a screw at the base same as the GRiSO stock shock.
GRiSO shock has precison tuning on remote "yea like that makes a difference to the bigger man" on that short travel shock.
Remove all the compression by turning knob counter clockwise and adjust the Rebound screw two and three quarters in from any direction. This will effectively set it in the middle.
Will require two people unless have a chock stand for front wheel.
You could do this naked though its advised to have all your bike clobber on.
For compression measure from two fixed points at the back of the bike then tilt bike onto stand and measure, place back onto stand and measure, then sit on bike feet up hands on bars and just lean/support with arm against a wall and measure.
Compression should have the bike sitting with you on it about 1inch and a quarter to 1inch and half of sag. Aim for just over 1inch and a quarter.
Includes from free length and bike weight.
This sets you into the shocks travel, it can then travel down and up without topping out.
With the rebound screw ride as is a mile stretch of road with a few bumps and rough surfaces, then adjust screw half a quarter soft, shock is marked S/H.
Ride same stretch of road see if like/ Adjust shock back and try hard see if like.
After is personal choice are no rules with rebound or precision damping, precision damping is really for race, factory "dot" default for road/street/hooligan should suffice.
Setting sag is only rule, think I've managed all that maybe once on one bike ever and that was a mountain bike
