Bottoming out??

Am I bottoming out? Dedicated track bike with stock suspension (2011 S1000RR). I didn't hear or feel anything so I'm not sure?

Close, but not bottomed out yet, I've gotten the zip tie on my forks down to about the 1 centimeter (cm) mark while track riding before they bottomed out. Front end start wiggling around in the bumpy braking zones when I noticed the front forks bottoming out.

Garage
Extend your forks completely and measure from the bottom of the fork tube to the top of the seal. Then check against the listed Max fork travel in the manual. That'll let you know where bottom is.

Zip-tie in front fork should be banned, because it causes much more problems than bottoming out...

No. You should be using about 80% of your shock, leaving 20% remaining.....

Because reaction to zip-tie-position is usually something random like this:

I believe that came from Dave Moss (not random). It's certainly not a hard fast rule, but it's a quick way to see that you are in the approximate range of suspension function.

Sometimes Dave Moss gives good info, sometimes bad info. That 80% vs 20% is really bad info.
