                               2000-up Honda CR125/250

*This link will lower the rear 1.0" on the 00-01 model, and approx. 1.5" on the 02-up models when using the Honda recommended race sag. (See chart below.) The CRF250/450 also uses this link,  therefore the CRF3 engraving. 
 

1. Raise the motorcycle with a bike stand, milk crate, etc., so the rear wheel is just slightly off the ground. Remove the two 19mm socket sized nuts that hold the "H" link to the rocker and the engine cradle and push the front link mounting bolt out the left side. The lower chain roller comes out with the front bolt. Then remove the rear mounting bolt. The swingarm may need to be raised slightly to allow the rear bolt head to clear the chain.

2. When installing the Kouba Links, (engraving to the outside/bearing end to the front) be sure the 90 degree grease fitting is facing down and should be centered between the link side plates. Engraving will be readable on the right side. (Left side engraving will be up side down and backwards.) 

3. Remove the center sleeve from the OEM link and install it into the new link.  Be sure you put the 2 step washers from the OEM link on the ends inside the seals after installing the center sleeve. Line up the rear link mounting holes with the hole in the rocker and push the rear mounting bolt in from the left side.  (You may have to raise the swingarm for the bolt head to clear the chain.)  Next, line up the bearing end of the link inside the front mounting brackets and push the mounting bolt, with the chain roller on the end, in from the left side.  (You will have to raise the swingarm to line up these mounting holes.)  Replace both the 19mm socket sized nuts and and torque them to 65 lb-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 3.10 inches with rider in full riding gear, standing on the pegs. Slide the fork tubes up until they barely clear the bottom of the stock bars, or no more than 3/8 inch showing below the standard line. If the links are for lowering purposes ONLY, sag can be set at 3.90", and will lower the rear of the bike 1.0" to 1.5" depending on the year model. The easiest way we have found to adjust the rear spring preload is to use a long punch to loosen the top jam nut from the right side and grasp the spring at the bottom and turn the spring and the nut at the same time. 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. The front forks can be slid up in the triple clamps approx. .375 inches until they contact the handlebars for lowering of the front. **IMPORTANT!  Top triple clamp bolt torque = 17 lb-ft.  Bottom triple clamp bolt torque = 14 lb-ft.  Disclaimer: Lowering the rear more than the front will change the geometry and could affect handling so be careful out there.

Chart below shows rear lowering amounts for the CR/CRF lowering links: (All amounts are measured straite up from the center of the rear axle with the axle/chain adjusters in the forward part of the adjustment range or as they came from Honda.)

*(CRF4 lowering links are "only" recommended for the 2005-up CRF450"X" as they can cause rubbing and geometry problems on other models.)

***** None of these links will fit the 1999 and earlier CR250 as the fork holes are a different size and who know what else.
