Home \ VF1000F Project Page \ Adjustable Rear Ride Height

This modification is performed on the stock VF1000 shock.  What is shown is a VF1000F/R unit, but is applicable to all VF's.  A kit for this modification will be available soon.  See the Performance Parts Page for more information.

The benefits of this are:
  1. Ability to adjust the rear ride height for added clearance and/or sharper handling
  2. Looks cool!

The following parts will need to be modified or added:

Here are the steps needed to perform this modification:

Step 1 - Remove rear shock from bike.  You do not need to worry about cleaning it, as shown.

Step 2 - Cut the shock tube 20mm above the lower clevis.

Step 3 - Remove the excess tube material from the lower clevis.  I chose to mill the clevis surface flat, but careful grinding will work.

Step 4 - Drill a Ø16.05mm (Ø.632in) hole in the center of the clevis.

Step 5 - Insert an M16 x 60mm long socket head cap screw into the hole drilled.  Secure using a thin hex nut.  This will serve as the adjustment device.

Step 6 -  Grind the head of the M16 screw down approximately 12mm (.472in).  You will grind until the the head is down to the bottom of the hex.  This is for clearance with the lower swingarm pivot.  Machine an insert for the new lower clevis to thread into (see below for drawings).

Step 7 -  Assemble and weld the insert to the shock tube (weld not shown).  Thread the new lower clevis into the shock.  This is the new adjustable shock assembly.  A second thin hex nut should be used to maintain height setting (as shown).
Step 8 -  To adjust the height after the shock is installed, the lower clevis will need to be disconnected from the swingarm pivot.  The above dimensions will allow the shock to have the stock ride height at the minimum adjustment.  The maximum ride height increase should be limited to 2.5in or instability may occur.  Don't worry, 2.5in makes a big difference!

More details (and hopefully more pictures) to come, check back soon!!
