                       Installation Instructions
             Fits: 1995-up KTM 400/620/625/640 Adventurer, Duke, LC4, SM, & 03-up SXC.
                                  Lowers Rear 1.75-2.0" (Depending on model)

        **Will not work on any of the 900cc + models with the linkless rear suspension. :-(

1)  Raise the motorcycle with a bike stand, milk crate, etc., so the rear wheel is just
     slightly off the ground.  Remove the 19 mm nut from the left end of the rear link 
     mounting bolt (rocker end) and push that mounting bolt out the right side.  (Raise
     up on the swingarm slightly to allow it to slide out easily.)  Next remove both (left
     & right) 18 mm nuts off the front link mounting bolt. (frame end) *You can keep
     that bolt from turning by holding it with the 6 mm nut that is on the outer ends.
     After removing both the 18 mm nuts, you can remove both links off the mounting 
     bolt ends and you should be ready to install the longer KoubaLinks. 

 2)  Install the new links in the reverse order of the removal by installing the small 
      end of both links on each side of the the front mounting bolt and install both 19
      mm nuts. When installing the KoubaLinks, the engraving is to the outside and 
      readable from the right side, the left link engraving will read upside down and 
      backwards.  Both links are identical.  Next, lower the swing arm down until the 
      holes in the links line up with the hole in the rear rocker mount, push the 
      mounting bolt in from the right side and install the 18 mm nut. Torque all three 
      18 mm nuts to approximately 35 ft-lbs.

3)   These links fit all of the above model KTM's, and will lower the rear of the 
      Adventurer and LC4 1.75 inches, or 2 inches for all other models. (*The bottom 
      of the spring on the 625SXC/SMC will contact the swingarm tunnel when fully
      extended and you may need to file the spring or the tunnel approx. .040" for 
      clearance. The rear ride height can be changed by tightening or loosening the 
      spring preload, but recommend the KTM recommended sag for your model if you
      prefer the above lowering amounts.  You may want to check the rear sag after you
      install these links, as some bikes have had the rear spring preload backed off 
      beyond the specs. in an attempt to lower the rear.  Sag: = (amount of vertical 
      movement of the rear axle FROM no weight to bike weight PLUS rider weight in 
      full riding  gear standing on the pegs.) This sag adjustment can be changed by
      turning the two large nuts on top of the rear spring.  (More preload = less sag, and
      less preload = more sag. Turning the spring preload nuts clockwise will increase 
      the preload and visa versa. The easiest way we have found to change the preload
      adjustment is to loosen the top jam nut, lube the threads on the shock, and turn
      the spring and all by grasping the spring body and turning spring, nut, and all. 
      *The spring & nut will turn easier if  the rear wheel is off the ground. 

4)  The front fork tubes can be slid up in the triple clamps approx. 1 inch until the top 
     of the fork caps are even with the underside of the stock handlebars.  Only slide
     the fork tubes up until the rider is comfortable with the way the bike rides and
     turns. If the front pushes or will not turn quick enough we recommend lessening 
     the rear sag over sliding the fork tubes up farther than the 1 inch.  Disclaimer: 
     Lowering the rear more than the front and visa versa can change the bikes 
     geometry and could affect the handling, so be careful out there.
