Rear Shock Adjustment

Notes

The Official Manual section on Rear Shock Adjustment illustrates how to measure preload and check sag.

Compression

The official manual's description here is adequate and this can be done readily by hand on the right side of the bike at the top of the shock.

Rebound

The adjustment knob is at the bottom of the shock facing rear, as described in the manual, and can be worked by hand or with a wrench with a careful reach into that area.

Spring Preload

The official manual illustrates the collar and procedure for spring preload adjustment, but does not recommend a specific tool, and there are clearance issues in that area for tools.

The adjuster sleeve diameter is 58mm (2.3").

A Stockton spanner wrench was found to be suitable for the job if modified as follows (per 2017 DSR Showa rear shock spanner wrench):

• Grind the nose of the wrench to fit the notches.
• Bend the wrench a couple of degrees to clear the Sevcon motor controller fins.

Obviously, a better solution is still worth seeking.

A small suspension wrench / ER collet spanner size 30/32 can be use even with the lack of clearance
