How to Raise & Lower the Yamaha R6 Rear Shocks

Updated April 17, 2017

Raising or lowering the rear shock of your R6, also known as adjusting the bike's "sag," is a very important part of setting the bike up for your weight and riding style. The rear shock is made to be adjustable because not every rider uses the bike in the same way, and motorcycle riders come in all shapes and sizes. Setting the rear shock to your weight and style will result in a responsive yet comfortable motorcycle that is a joy to ride for hours at a time.

Take your R6 for a test ride around the block or up and down the street. Take a few tight, quick corners and accelerate a few times quickly from a standstill. Pay attention to how the rear suspension behaves, how far the bike sinks when accelerating and taking corners, and then decide whether to make the shock absorber stiffer for more responsiveness, or softer for more cushion.

Set the R6 on its kickstand and examine the rear section of the bike. Below the tail section, between the seat and the rear wheel, you should see what appears to be a large spring. This is the rear shock. The adjuster for the shock is at the top just beneath the tail. You adjust it using a spanner wrench, either clockwise for softer or counterclockwise for stiffer.

Twist the adjuster of the shock using a spanner wrench in the appropriate direction until it clicks once. Take the bike out on another test ride to feel the difference this adjustment makes to the ride. Return home and make more adjustments if necessary, repeating this adjust-and-ride procedure until the rear suspension action is as stiff or as soft as you like.
