Sorry for waking up an old thread but there was no point starting a new one.

so If I weigh about 175-180 pounds with all my gear, the rear preload should be set around 5 or 6 I would think? I have no idea what mine is set to but feels like it was set for a heavy guy.

So I got CBR500RA 2016 model recently. Factory settings for the motorbike is 3 front 3 rear. I'm around 160lbs with gear on.

Measuring sag with these values showed me that my sag is 20mm front and 35+ back (cant remember exact value now).
According to internet, both front and rear sags should be around 30mm, then I go on from there and adjust if I feel the need for it.
I've turned the rear one notch (to four), and that gave me 31mm rear sag which is OK.
However, on the front I only can turn the bolts to 4.5 notches which gives me around 27-30mm front sag.

Now the question.

Front fork settings don't make much sense to me. I consider myself average weight for EU riders (~155 lbs), and if bikes default setting put me at 20mm sag, why is that? People say the bikes suspension was set up for Asian riders, which are usually not fatasses compared to rest of the world, so logically I should've MORE sag, not LESS than recommended? It feels weird that I have to turn the bolts all the way up to even come close to recommended sag for street riding. What people that weight less than me do in this case?

did you turn the front adjuster in (down) or out (up)?

Sorry that nobody saw your post and responded. Probably too late now, but I'd think you'd be around setting 4. Best to check sag properly, though, as noted at the top of this thread.

I'm currently rocking the front adjuster all the way out (softest). Zip tie method shown this is the correct settings. I need to re-measure front sag anyway, since the forks have broken in, and also wanna see if handling feels better if I turn the adjusters in a bit.

this is another common misconception about suspension.... in particular front forks - using a 'thicker' or higher weight fork oil does not make your suspension harder. only slower. the fork oil has to pass through small valves within the fork which control the damping. thicker oil simply takes longer to get through the holes. so although it might feel like its firmer (when bouncing it up and down stationary in the garage) the reality is with the heaver/thicker oil it is slower to react to bumps, and slower to extend back to its original length ready for the next bump because the oil cant get through the holes in the valves quick enough.

the only real way to make the suspension harder, is to change to a firmer spring

Did you measure the full extended length of the fork with the weight lifted off it? and then with you sat on the bike (off the sidestand, both feet on the pegs, leaning forward to the bars) and fully dressed in all your riding gear and helmet.... ?

You have to set the rear measure front adjust front, re measure rear adjust then re check front having to much sag in rear lifts front making front tire light causing wobble at high speed. This is why you keep going back and forth until the whole bike is right try 5 on the rear and recheck adjust front and test ride I believe I read on Honda somewhere the bike is set up for a 150lbs rider on US models.
