All you will need is two T handles, a flat head screwdriver, and the information provided in this video. Take command of your bikes performance by way of truly understanding your high and low speed adjustments settings.

Suspension Compression and Rebound Adjustment

What's up out there? It's JT, here at the Rockstar Energy Racing Shop in Corona, California. Today, we're going to talk about compression and rebound adjustment on your rear shock.

What is compression adjustment?

How stiff overall the shock is.

What is rebound adjustment?

How fast or slow your shock decompresses.

Tools for Adjustment

The tools you'll need for this adjustment:

  • Flat-blade screw driver
  • 14T-handle for some shocks
  • On other shocks you'll need a 17T-handle for your high-speed adjustment

Your compression is broken down into two adjustments:

  • Low-speed adjustment
  • High-speed adjustments

Both of your adjustments are located on the top of the shock near the reservoir. Your low-speed adjustment will affect how stiff your shock is on the face of the jump. Your low-speed adjuster is the flat-blade screw in the center:

Your high-speed adjustment is the 14mm nut on the outside.

Your high-speed adjustment would affect how stiff your stiff your shock is on harder hits, say in breaking bumps.

Low Speed Adjustment

A good starting point on your low speed adjustment is around 12-clicks. To do that, we'll turn our adjuster clockwise, all the way in. Once you feel resistance, you've hit 0. You don't want to force it past any resistance or you will damage the shock body.

We'll count from 0 all the way back out to 12. Back out the adjuster counterclockwise starting from 1, and we'll count to 12 clicks.

High Speed Adjustment

Unlike your low-speed adjustment, your high-speed adjuster doesn't have clicks, so you adjust in turns. To adjust the high-speed, we'll turn the adjuster clockwise until it seats, and we'll back it out; around 2 to 3 turns.

The first step to adjusting the high-speed is to turn our adjuster clockwise, all the way in until you feel resistance. Again, remember not to damage the adjuster. Once you feel resistance, you're at 0. We'll back our adjuster all the way out to 2 turns. We'll count in half-turns. Half, one, half, two.

Now our high-speed adjustment is set in the center, along with our low-speed adjustment. Once we are happy with our settings, we can move on to our rebounder adjuster at the bottom of the shock.

Rebound Adjuster

Your rebound adjuster is located underneath the swing arm on the right side of the motorcycle. To adjust our rebound, we're going to grab a flat-blade screwdriver and go around the bottom of the right side of the bike.

It's the low-speed compression adjuster; we are going to turn it till it bottoms clockwise, until we feel resistance, then count out counterclockwise to 12. Keep in mind that all your adjustments are set to a starting point. Once you get out on the track, you can fine-tune it.

Rear too stiff:

  • Soften by going counter clockwise on your high/low speed adjusters counter-clockwise

Rear too soft:

  • Stiffen by turning your high/low speed adjusters clockwise.
