Subject: 2009 Honda CRF450R

Which linkage would you recommended for me I am 5’ 11” and intermediate advanced rider the 7/8th or the 1.6”?  and which linkage is similar to the pro circuit linkage?

***************************************************************************************************************

Nick,
The CRF9-2 is closest to the Pro Ckt. link and would be recommended for supercross/motocross.  It drops the rear about 3/8th inch farther but will work about the same if you use 3.5" of rear race sag rather than the 3.9" that Pro Ckt. recommends with their link.  The CRF9-3 link is more for the max lowering with the plushest ride, but keep in mind the 09 CRF450R is on the fine edge of supercross design and has too much trail for most other types of riding without going to more triple clamp and/or front axle offset to reduce the trail. Here is the URL to a couple articles for more info. http://www.tootechracing.com/Too%20Tech%20Hidden%20aspects%20of%20trail.htm http://www.tootechracing.com/too_tech_review.htm
Thanks for your inquiry and please let us know if we can help with anything.

                   Installation Instructions

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 and flat washers (front bolt nut is on the right, the rear bolt nut is on the left) that hold the stock “H” link to the rocker and the engine cradle. *If you have the Pro-Moto Billet side stand 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 front mounting bolt out the left side first, then push the rear mounting bolt out the right side.  *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 right 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 90 degree grease fitting on the link is facing down and the engine breather hose is centered inside the clevis in front of the link's cross tube.  *Left link engraving will be upside down and back wards, right side will be readable left to right.  Grease the fitting now as sometimes tightening the mounting bolt nuts can seal the bearings too tight to allow the air to escape when pumping the grease in.

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" (CRF9-2 link) and 3.25” (CRF9-3 link) with rider in full riding gear, standing on the pegs.  If the link is used for lowering purposes ONLY, rear race sag can be set at 108 mm/4.25 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) Loosen the triple clamp pinch bolts and slide the fork tubes up until there is 1/2” showing above the top triple clamp including the thickness of the fork cap with the CRF9-2 link and 1” showing above with the CRF9-3 link.  *Do not over torque the triple clamp bolts.  (14 ft. lbs. lower, 17 ft. lbs. upper)  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.
