2021 Z900
Z900 newbie

I am 165 lbs.
No pillion rider

I find the stock suspension rather stiff.

What are my options.

Thanks a bunch!

You are near the ideal weight for the suspension. I assume you did the obvious...adjust the spring preload and damping? (front and rear)

Did yours come with an owners manual? I ask because the info on how to adjust is there. Feel free to post your sag.

2020 and 2021 are little stiffer than 2017-2019, at least rear shock spring is stiffer, but the forks also have different springs so maybe they are also stiffer.
Im 94kg (207lbs) without gear and with stock fork preload, rider sag is 37mm.
Rear shock sag i had to adjust. With 6 (or 7?) visible threads (stock is 2 visible threads), rider sag is 44mm (still have free sag, 8-10mm).

Hey I have a noob question. When you are saying there are 7 visible threads. You are counting down from the front of the bike or "top" of the shock down to the locking collar correct?

I am 66kg-145lbs without gears. Stock settings were totally out on my 2020. I had to remove all preload on fork and shock (only one thread left) and close the rebound, especially on the rear. Still a bit firm,  but it's ok from a sporty bike like my z900. Closing the rebound removed the pogo stick feel.

This photo is just after a track day, with some big compression. As you can see, I am far from bottoming out the fork, but I don't feel stress on my arms any more, unlike the first time where I couldn't reach more than half the travel.


Stock suspension are OK for me, but I don't have any room for tweaking. They are definitively made for riders between 75-90kg, 165-198lbs.
