Is this the correct one to upgrade my thou?
It looks similar to the one's with electronics on it but the seller says it does not have wiring on it. I'm not sure, maybe the wires are cut off, or maybe it's the right one.
-
Does it have any damping adjusters on it?
-
The pictures are all i have for now, but it doesn't look like it.
-
I can also get a brand new 2020 r6 shock, but for that one i also dont know if it will fit. Don't know the specs yet.
-
whay not get a hagon or something ?, must it be a bmw one
-
No it doesn't have to be an R6 or bmw shock, it's just that there's a lot of info to find about them. Not familliar with the brand you said.
-

If it hasn't got the adjusters shown it's of no use to you
-
I've asked the seller and unfortunately it's not the one i need.
Thank's for the help.
i'll probably go for the R6 shock. It's for free and alot newer but not looking forward to search for the correct dogbones. Rather have it a bit higher in the rear than lower.

You can order dog bones by length from this site (https://www.sfpartsltd.co.uk/jack-up-kits-available-for-various-models.html) if you're not 100% certain on the length you need at £15 a set you could order a few sizes and return the ones you don't want to keep under distance selling regs (as long as they are in "as new" condition). Maybe grandmother egg sucking lesson but shorter dog bones equals more height at the rear.
-
From memory, I think 130mm dogbones bring the R6 shock close to standard rear ride height, 127mm or even 125mm would raise the back-end. I have the opposite problem - am borderline short-of-leg, so have 135mm dogbones fitted to mine for a very slight drop
-
That website is a great advice, thank you.
This saturday i'm picking up the r6 shock, i know i have to drill out a hole to 12mm but i also need custom bushes? Do you know what size and shape they must be?
I'm from the Netherlands by the way but i'm sure i can find a guy here that can make them.
-
If you bore the shock's top mount out to 12mm, you just need a washer either side of the shock to take up the slack.
Alternatively, you could fit top-hat spacers like the ones shown here: https://foc-u.co.uk/index.php?topic=8167.25 (Post numbers 41 & 45 from 'D. Curzon'). These were however the spacer dimensions for fitting the shock to a Fazer 600. For the Fazer 1000, the wider part of the spacers should only be 3mm depth instead of 5mm. Currently running a pair of these on my own bike with R6 shock fitted.
-
This is the one i picked up today.
It's a near new 2017 R6 shock.
Also found some dogbones with the holes at 125mm center to center.
Do you know if i have to grind the top of the shock a bit on this one and do you know what the differece in hight will be with this 5mm shorter dogbones?
This guy i picked up this shock has alot of them and also has a lot of the s1000rr shocks.
-
The dogbones are oem ones from a yamaha bt1100
-
The shock
-
The 2006-07 2cO version (with separate compression adjusters at the top of the shock) won't fit the FZS1000, but the 2008 onwards 13s version with combined compression adjusters does fit. That shock looks like the same overall design as the 13s version with combined compression adjusters, it's just the the spring preload mechanism that is different.
-
Just fitted the shock, it was really easy to do.
Drilled out the top to 12mm and with two 2mm spacers it fits perfect.
With the oem dogbones from a Yamaha bt1100 the rear is just 1.5cm higher so the rearwheel wont touch the ground when the bike is on the centrestand.
Haven't tried to ride it yet but am already a happy man.
-
Well done, you should find the bike handles much better now, let us know how you get on.
-
I will, i hope it doesn't run so wide anymore.

Have you dropped the yoke down the forks? If not try doing that so you have about 10 - 12mm of fork leg showing above the yoke, that should also help.
-
Thank's for the advice, does that help because the wheelbase gets shorter or because there's more pressure on the front?

It puts more weight on the front which has the effect of quickening up the steering making the bike much more flickable and predictable through corners.
I found a 25mm ride height jack-up kit and dropping the yoke down the forks gave really good results. As an experiment I tried a 50mm jack-up kit with the yoke dropped but this put too much weight on the front and made the handling worse, so I now have the 50mm kit and the yoke at the stock position which works just as well as the 25mm rise and the yoke dropped. As dropping the bike down the forks is free and doesn't take a lot of effort to do or put back to stock it's definitely worth trying just to see how you get on, don't go too far though as you may hit the mud guard under sharp braking, 10 - 15mm should be fine and make a noticeable difference to handling.

It changes the rake and trail on the forks.

This is correct, and it also does affect wheelbase, learned something new today :D This tutorial was also helpful - https://lifeatlean.com/teach-me-suspension-simple-geometry/ (https://lifeatlean.com/teach-me-suspension-simple-geometry/)
