Sachs shock & Marzocchi forks service vs upgrade

I've never gotten my suspension serviced, but thinking of getting it done on Sachs shock and Marzocchi forks on my 2015 F3 800 (nearing 10,000 km).

A local suspension specialist who is always present at my trackdays told me that I should upgrade the springs in my fork and think of changing the Sachs shock to something 'better'. Is that Sachs shock a bad model??

Is that worth considering? Or is simply servicing the suspension and getting fresh oils in there enough?

Note that for my riding experience, I feel like the bike's suspension is great. But I'm no expert and maybe I'm missing something that I am unaware of??

First thing i would ask is does the bikes suspension give you the feedback and confidence you need to ride at the pace you want safely at the track? if so maybe just a freshening up and spring swap for your weight is fine.

For many of us, a change to the fork springs and valve stack is pretty common (or cartridge kit), and depending on the model and use of the bike, you mentioned track riding, the shock might need a spring and revalving if not replacing.
Sachs and Marzochi are, bottom of the barrel suspension components to be honest.

First of all, I don't think that's true. My Sachs and Marzochi work fantastic. But to not start a fight and keeping inline with the topic, bottom line is....if your not happy with the setup change it!

Unless you have oodles of money why not try what JDGun said and change out the internals first. Have your suspension friend order you the correct parts based on your goals and also have him set it up for you.

If that doesn't accomplish what you are looking for then look into replacing.

You may be right, they may not be the bottom of the barrel ... but you can see the bottom from where they are LOL Some stock low cost showa/kyb stuff is simply terrible.

Well setup stock suspension can be better than expensive high quality stuff that is setup wrong.

With a few upgrade pieces most stock suspension can be made very good and can be setup to work well for the rider.

Look at FG and Andreani for parts/kits specific to your F3's stock components. All joking aside the stock suspension can be made to work quite well. Best of Luck, Cheers

The Sachs shock is junk. Period. There's no point in throwing money at it. The forks can be "made to work" and the ceiling is much higher than the shock. That being said I have a Penske shock for sale .

It really is about what works for the rider and their intended purpose. hey if your just riding to Starbucks, and zipping along highways with some on ramps, sure the stock stuff is good enough, with maybe just new springs.

Just wanted to add, I had commented about the Sachs shock on a Dave Moss video on youtube (the one where he was testing a JRI shock on his F3 800), and he quickly replied saying the following:
"I rebuilt my Sachs shock (revalve and respring) and it performs extremely well."

All that to say, I think I will try that route (at Race Tech) as its only a $300 affair. I use the bike on the track only but I am nowhere near the fast guys (working on it working on it...) but jesus @dudman, your K-Tech must be trick but sadly out of my budget for now.

Check out Dave Moss, suspension guru, on Youtube. He either has a F3 675 or 800. He swears by the stock suspension and says its one of the best in the business. Don't listen to others when they say it's crap. They either a) have more money than sense or b) looking for an excuse to justify their bad riding. Perhaps get the suspension serviced and get it setup for your weight with riding gear. The suspension has FAR more potential than 99% of riders... especially on the street.
