Suggest Fork Settings for 180lb rider

Last week I replaced the fork seals, bushings, and oil, and I was wondering if anyone can give me some basic suspension settings for my weight. I did a careful job on the fork work, and I followed the directions in the how-to section closely, and I made sure I used Honda's SS8 10W fork oil, and set the level to 135mm.

After doing the work I reset the the fork dials to their previous places;

preload 7 turns clockwise
rebound 3 1/4 turns clockwise
compression 12 clicks clockwise.

I took a ride and put a zip-tie on the fork tube and noticed that without any hard breaking or crazy bumps by the end of the ride it was within 1/2 inch from bottoming out. This seems like too much travel to me, but what do you guys think? I am 180lb before gear, could you guys suggest moderately aggressive settings for my weight? I do track days a few times a year.

Set your sag with preload, ride and recheck suspension travel used. Add compression damping to make the fork more resistant to compression.

google rc51 sportrider settings for a comp/rb setting comparison.

FWIW a good set up uses nearly all travel without bottoming out.

There is no specific "setting" for 180lbs, but your preload setting will be different based on your weight.

Like KW said, set your sag first (with gear on and forks warmed up)...then adjust from there.

2015 Grom (under construction)

Thanks for the Sportrider chart information. I will start there. Question; when measuring the suspension settings, do I measure from fully CW (soft) or CCW (hard), for all three adjusters?

You should always start with fully closed and work your way out (for compression and rebound). Sag settings will be based on your weight (recommend with gear and suspension warmed up)...and adjust based on mm.

I just went for a ride after using the Sportrider settings and the bike felt much better, and there was much less front end dive. Thanks guys!

Rebound Damping to 2 turns from fully CW
Compression damping 8 clicks from fully CW
Pre-load 7 turns from full soft

Now the dimples on the Rebound Damping Screws face each other, where as before they were totally off in different directions, so possibly measuring from fully CCW like I originally did will not result in they being the same for both forks. Either way the bike feels way better now.

Rebound and compression settings, always start from full closed - clockwise - then count the clicks as you go softer - counterclockwise.

This is a David Moss video. For setting sag and rebound.

What is your sag?
