Hello all, I have my new 2006 Griso V1100 since last september and I noticed that suspension settings are on the hard side. I revised this forum and found very useful tips to adjust settings and I did partially, because I have a couple of doubts I would like to solve here.
This settings are in a topic posted and threaded in 2008:

Front
compression: 1/4 T (stock: 1 T)
rebound: 2 1/4 T (stock: 1.5 T)
preload: 5th mark (stock: 4th)
sag: 37mm (stock: 35mm)

Rear
compression: 1/4 T (stock: 1.5 T)
rebound: 40 clicks (stock: 17)
sag: 25mm

Can anybody clear up for me what "sag" means and how and where is it measured? I revised my owners manual and workshop manuals and did not find a clue.
 
Excellent, last night I began to read and a new world opened...I am begining to understand how motorcycle suspensions work.
Thanks, GT-Rx
 
Hello guys,

Just to thank the forum for the suspension settings and advises for the Griso.

I changed the original settings as posted before and I got a much soft and confortable ride in my everyday city conmuting here in Mexico City. I have to tell that streets here are not fine and lots of bumps are found all around, so new settings are perfect!

Happy New Year to everybody!
 
Glad the settings are working well. It is amazing how many folks don't take time to do proper adjustments and they end up missing out on greatly improved riding. My area dealer, Moto Nexus, is inviting a local suspension shop to do a clinic for folks. This is an inexpensive task that you can often have done at local tracks by vendors too.

Safe travels

Bob

i only understand the basics sag,compression,rebound ,but it works wonders for me being a light weigh rider.Really is an amazing subject :) :) :)
 
Im a pretty light rider (about 155 lbs) but it seems, even to me, that the front forks are a little under sprung. im down to a little less than 1/4 turn compression on my front, and it nearly bottoms when i hit a driveway at 10 mph.

Yes, i could go slower into the driveway, but the point is, it seems to me like it needs some stiffer springs.

have you got your sag set correct because if not its pointless trying to set it up.
I have upgraded to 15w oil which i find works for me once you get use to it and i did not have to take fork legs out i cheated and drained oil from compression nut its simple to do and took half an hour
 
Setting your sag will tell you if your springs are too soft or not. If your suspension bottoms it could be the springs are too soft but it also could be a lack of dampening.
When you set your sag you end up with a certain amount of sag with the rider on board (race sag) and also a certain amount of sag without the rider on board (free sag). If the bike does not have enough free sag (or none at all) when the race sag is correct then it means the springs are too soft. There is a little room in the numbers for personal taste but the general rule is the same.
Also worth pointing out is the preload adjustment that is used for setting the sag does not make the spring stiffer or softer unless you have aftermarket progressive springs. It only sets ride height/sag. If your ride height is too low then among other things the suspension may be more likely to bottom. This is not because the spring is softer but rather there is less travel available before it bottoms.

nice one,i dont mention ride height because in the past its been a nightmare to get some people to understand,and trying to tell them you cant change a springs stiffness is impossible.Wish i could explain things in your style,trouble is i can barely read and wirte :) :)
