OK, so I replied to another Thumpertalk member in a pm message what my recommendations were for XL600R suspension upgrades and though it a good idea for us to get everyone's thoughts and hopefully some pictures on the topic. What follows is my experience and advice, please contribute, elaborate criticize, critique, and otherwise add to the greater knowledge for all us XL600R owners. As a lead in, I have mentioned in other posts using XR600R and XR650L suspension parts on an XL600R to upgrade or improve the handling, feel, ground clearance, and coolness factor, and yes, a lot of it does work (works real good too). So with respect to using the XR600R and XR650L suspension parts on your XL600R, the mods are a sure way to improve your XL. Fortunately Honda uses the same size steering tubes and bearings for all of their larger dirt bikes, so an XL600R, XR600R, XR650L, and XR650R all use the same bearings and the head tubes in their frames are the same length, This means that you can use whatever front end you want. However, there are a couple hitches - first, the older XR600R and all XL600Rs used a smaller diameter axle, so if you go with an older XR600R set of forks, (I have a set for my XL), then you can simply use your original XL600R front wheel. If you go for an XR650L or later XR600R set of forks (I don't know what year the axle size changed, but I expect it was around the same time the XR650L was released in 1993), then you will gave to get a larger diameter front axle and wheel. Another thing to keep in mind is that there are two different diameter front brake rotors, so if you get one of the newer bikes, you will need the right caliper bracket to mount the caliper to the fork. You will also need an XR600R or XR650L front brake hose (either will do) as the XL600R brake hose is not only too short, but it also has that funky steel line that crosses under the lower tripple clamp that won't work on the XR triple clamps. The older XR600R with the smaller diameter axle, and the newer XR600R and XR650L all have the same diameter fork tubes, so they all work with the XR650L triple clamps, which you will want to use because they come with a place to mount the speedometer and headlight bracket. Also, you will have to rig up some kind of an adapter bracket to go between the XR650L speedometer bracket and the XL600R speedometer because they mount differently. I used an old aluminum road sign and cut out an adapter plate with a grinder and drilled some holes in it - it works great and was free.
