Rear shock absorber settings
« on: June 26, 2020, 09:18:35 pm »
Manual states nothing about settings for rear shock absorber.
Does some one have a general PSI range for say ‘sporty and stiff’ to soft and cushy?
I am familiar with measuring sag and adjustments.

Probably best to go by sag.  You can tweak from there.  I'm sure there will be an abundance of opinions to follow.......and mine is worth what you paid for it! ;)

For normal riding,
I liked about 40 PSI.
For Sporty, I went up to 50 PSI..
At those pressures, Sag will still be a more than 35mm, but closer at 50.
I think I used 2 on the damper adjustment.

On the front, the springs are too soft to get near 35mm regardless of how much preload you add.

At the rear, I've gone to a C-14 shock and cranked in a lot of preload.
I stiffened the front by shortening the front spring 4" {added a 4" spacer} and added an Emulator to give more adjustability.

Ride safe, Ted

I used the middle setting on the damping, and 20-25 psi air.
I was a svelte 210 at the time.

Loaded for a trip about 40 psi.

As Ted said, the OEM suspension on the C-10 is 'soft' by today's standard.
I eventually did similar upgrades as Ted.  Straight rate springs and emulators
up front with a C-14 rear shock. 

The factory set up delivers a very comfortable ride.  The upgrades will
sacrifice some of that comfort for performance/stability.

Appreciate the input. Will any year Concours14 rear shock fit the 2006 ZG1000?

Any year C-14 shock will fit with some simple modifications, but it will raise the rear about 1 1/2".
Many install a lowering Rocker or Lowering Link to make it level again.

Others have installed a ZZR-1200 rear shock as they also fit, require the same simple mods, and do not raise the rear of the bike.
Bike will be only slightly taller than stock.

Ride safe, Ted

I adjusted the SAG on mine a few hours ago, and came up with these numbers:

Traseira (Rear)
L1:  15-1/4”
L2:  12-13/16” ;  13-1/2” ; 13-1/4” ; 13-3/4”
L3:  12-1/2”     ;  13-1/4” ; 13-1/16” ; 13-1/2”
Final: 1-5/8” (1.625 ; 41.275mm) @ 50 psi and damper on 4.

Dianteira (Front)
L1: 3-11/16”
L2: 1-9/16” ; 1-13/16” ; 2
L3: 1-3/4”   ; 1-3/4” ; 1-3/4”
Final: 1-13/16” (1.8125 ; 46.0375mm) @ 3/4 turn from fully “closed”.

I am a “strong” guy with just 270 lbs. And a Givi trunk...

As y’all can see and imagine, it improve handling and stability a lot.

HPazzoto;    Is the L1 on the front taken with the wheel off the ground?
                        Seems to be a unusually small number.
                  Do you have all your preload cranked in, in the front?
                        A C-10's front springs are weak. With your weight, you will need all the preload you can get.
                        Your front sag of 46mm is almost 1/2 your available sag. That leaves little travel to absorb bumps.

Target sag for both ends should be 35-40 mm..

Ride safe, Ted

Hi Ted. Yes, both wheels off ground for L1. On the front I measured from lower triple clamp to top of fork cover...

And on the front it’s almost all cranked in: I fully screwed in and backed out only 3/4 of a turn. When adjusting I felt a huge drag on the front fork, and also looking at L2 and L3, I can tell it needs service. Same goes for the rear shock...

I’ve looked here in the forum and at the end of the year I’ll service/mod both suspensions. The rear ZZR1200 shock seems like a good option, and for the front a different spring rate with emulator...

For now I’ll just enjoy it the way it is and try to avoid potholes as much as I can, while the weather is still good for riding...

Some say the ZZR shock has soft springs too.
I'm unsure. Think you'll be ok with just cranking up the preload.
  I'm using a C-14 shock and a lowering Rocker. {As I already had the Rocker and a C-14 shock}

On the front, I was too tight to buy aftermarket spring.
I just removed 4" {of the tightly wound coils} from a stock spring, and dropped in a 4" PVC spacer.
Stiffens it up nicely. Costs nothing.

Ride safe, Ted
