 Installation Instructions
Fits: 2010-12 Suzuki RMZ250/450 & 2017-up RMX450.
KoubaLink PN: RMX2 & RMX3. 
Replaces stock link PN: 62600-28890
RMX2 lowers the rear 3/4" &  RMX3 lowers the rear 1 5/8".

*The 2013-18 RMZ250 &  2013-17 RMZ450 requires us to drill out the fork end eyes to 14 mm. 
This link replaces Suzuki's stock link PN. 62601-28830 
        Please remind us if your bike is one of these models.  :-) 

* For installed pictures on a 2010 RMX450Z scroll to the bottom of this page. 

     RMX-2 Link Shown Above 
1) Raise the motorcycle with a bike stand, milk crate, etc., so the rear wheel is just slightly off the ground.  Remove the two 17 mm nuts  that hold the stock H link to the rocker and the engine cradle. *If you have the Pro-Moto Billet side stand or the RMX model, the side stand/mount with the left foot peg must be removed before the front link mounting bolt with the chain roller can be removed.  Push the bolts out the left side/front mounting bolt first.  *The swing arm may need to be raised slightly to allow the first bolt to slide out freely.
2) The new links come with only the bearings and seals, so install the center sleeve & both step washers (flat side out) from your old OEM link into the new KoubaLink. Install the new link on the bike (rear mounting bolt first) by pushing the mounting bolt in from the left side.  You will have to raise the swing arm to align the front mounting holes and then push the mounting bolt with the chain idler in from the left side. Be sure the grease fitting on the link is facing down.  *Left link engraving will be upside down and back wards, right side will be readable left to right.  Pump some grease into the fitting now as sometimes tightening the mounting bolt nuts can seal the bearings too tight to allow the air to escape.

3) Install the washers and 17 mm nuts on the mounting bolts and torque to 35 lbs-ft. 

4) For the best performance, set the race sag (amount of vertical movement of the rear axle FROM no weight to bike weight plus rider weight) at 3.5" with the RMX2 link and 3.10 with the RMX3 link, rider in full riding gear, standing on the pegs. Loosen the triple clamp pinch bolts and slide the fork tubes up 1/8th" to 3/8th" depending on how quickly you would like it to turn with the RMX2 link and until they almost touch the underside of the stock handle bars with the RMX3 link. Do not over torque the triple clamp bolts.  (14 ft. lbs. lower, 17 ft. lbs. upper)   If the link is used for lowering purposes ONLY, rear race sag can be set at 100 mm/3.9 inches.  The RMX2 link will lower the rear 3/4" and the RMX3 link will lower the rear 1 5/8th inches.  The easiest way we have found to adjust the rear spring preload is use a long punch to loosen the top jam nut from the right side, grasp the spring at the bottom from the left side and turn the spring and the preload nut at the same time.  **You may have to put some lube on the shock threads to allow the nut to turn freely.  Turning the spring/nut "clockwise" increases the preload and decreases the sag.  **Do not forget to tighten the jam nut with the punch after setting the sag.

5) For additional lowering of the front, the bars can be spaced up by installing a washer of 1/4" max thickness on top of the flanged washer above the top rubber mounts.  This will allow the forks to be slid up farther but is not recommended unless you require the quicker steering as sliding the fork tubes up farther could allow the tire to hit the fender when the forks near bottoming.  *Disclaimer:  Raising or lowering the rear more than the front can change the geometry and could affect the handling, so be careful out there.
