OK. Over the weekend I decided to attempt lowering of the new 2013 CRF250L. This is my wife's new bike and with an inseam of 27" her feet were about 2" off the ground. I had to do something or she wasn't going to ride it. The stock seat height is 34.75". so I lowered the forks all the way and rechecked finding 34.5" was the new seat height. This wasn't going to cut it so I looked for another way to do it. Then I saw this As you can see. This is the bottom of the shock and there is ruffly 2.25" between the bottom of the shock and the mounting bolt. This is a greater distance than any other bike I have seen. All we have to do is move the bolt hole up and you lower the bike. However with that said there is a magic number for this movement. I wanted to maintain the ability to return the bike to stock height therefore I would have to keep the stock mounting location. I also wanted to maintain the same distance from my new bolt hole to the edge of the next hole. so there was enough "meat" left on the shock so there wasn't a bending or tearing issue. That magic number was determined after some careful measuring and will be reviled latter. Lets start the breakdown. First put the bike up on a stand so the rear wheel is off of the ground. Next put a strap on the rear wheel over the fender so that the strap is snug enough to hold the weight of the rear assembly. Next remove the seat. Do this by removing the two long allen bolts on the back of the seat. Now remove the side panels. There is one allen per side. This will give you access to the rear shock upper mount bolt. To access it you will have to take the rear brake fluid reservoir. Don't turn it over just take it loose and push it lower under the mount. In this picture you see the reservoir and the upper shock mount. Next disconnect the lower wish bone linkage. Now disconnect the lower shock mount seen in this picture. Now using the strap over the rear fender and connected to the rear wheel raise the rear wheel about five inches. Next remove this upper rear shock mount bolt. When you take this loose you will have to have an open ended box wrench on the nut. Put some grease on the surface of the wrench. This will capture the lock nut and washer. Do this for install as well. When this bolt is removed the rear shock can be dropped out the bottom. Now for the easy part. The Magic Number 1-7/16" You need to center your hole on this measurement taken from the bottom of the shock. Now drill this hole to match the existing hole size. Be sure you file off all burrs. When done you should have this. Now you you can reassemble in reverse order. Be sure you use blue Locktight where used from the factory. Which are the side panel bolts. The result of your labor will be the following You get the tire raised three inches and still maintains 8.25" tire to fender clearance so you will not bottom the tire out on the fender at full compression. Whit this mod along with lowering the forks the static seat height is now 32.75" This is still a bit much for my wife with the 27" inseam. She can kind of get the balls of her feet on the ground. But it will have to work. I will be switching out the springs for lighter ones once they are available. Next you will have to lower your kickstand. I took 1.5" off of mine. I would recommend 1.75" however. It just don't the the BMW lean I have become accustom to. This is also a good time to enlarge the foot as well. Now just give it some paint. The finished product of your labors.
