    DLC is Diamond Like Coating. USD is just short for upside down. The lower triple is stock 05-06 CBR600rr. 204mm c-c spacing and 30mm offset with 53mm clamps. Superbike forks [916, 996, 848, 1098] are 53mm lower and 53mm upper. I went with this lower since it needed no work to fit the frame. The upper (02 on Monster), however needs to be bored from 50mm to 53mm. The c-c spacing is 205mm but there is enough meat to move the centers in to 204mm. The offset is also 30mm. I figure the 0.5mm (each side) difference can be taken up in the axle easily enough. The right leg floats enough to adjust it. The calipers will have enough space in them as well. I'll upload more pics once I get the replacement lower triple. I'll get it tonight but I'll have to press out the race and put in the roller bearing tomorrow at work.

    One other thing I had to do was design a bushing to fit the top of the Honda stem and clamped inside the Ducati top triple clamp. I'll upload pics of this later too.

      The front end plan sounds good, the 1098 forks are good quality (although in stock form setup on the stiffer side, especially in compression damping and spring rate), and it is definitely worth it to work with these forks. The right way to compensate for the difference in fork spacing between the CBR and Monster is to remove 0.5mm from the fixed side bushing on the front wheel and let the axle protrude 0.5mm on the floating side - this way the wheel is still centered.

        This sounds likeep a really solid build. Cool stuff.

          Yup, that's what I'll do. Thanks JanM. Now that I have a lathe, it will be easy. In my younger days, I would have taken it to the belt sander. Hopefully I can dial the forks down enough to still be compliant with my weight of 160. I'll have to weigh myself fully geared tho.

          You're right but I did see both references. Wasn't sure which one was correct. Thanks Eric! It will be better when I get the chain roller! Parts are trickling in...

            Well, folks, I F'd up! The CBR lower has more offset than the Duc part. I should have taken BTT's idea of adapting the Monster lower with the Honda stem. I guess now I have no choice. I hate it when I read the wrong information on the internet and count on it before buying parts. Crap! I could have sworn both parts have the same offset! I just went measured them. The Duc top is definitely 30mm. The Honda is about 2mm more. Can someone confirm the offset? I know a few of you have 05-06 triples. It looks to be 32.5mm.

                Depends on year - some are 30mm and some 32.5mm (off top of my head, don't quote me). Think early (05/06) is the 32.5 and the later are the 30mm.

                Can you overbore the top triple and make an offset bushing?

                WW

                (PS - I believe I have one of these triples that I'm not going to use right away - hard anodized in black - switchable insert for either offset).

                  It would have to be 53mm and 204mm c-c spacing. But, you just gave me an idea with that triple. Since the Duc top has a large 40mm opening, I just need an insert like yours! Is it an eccentric shape or do you have two inserts? Can you make me one please! 40mm OD with a 2.5mm offset; 25mm tall. Let me what you think.

                  This way, I don't have to change the bottom. On top of making the insert for the Duc bottom, I still have to shim the 54mm opening and compensate for the 205mm c-c spacing.

                    My triple design is an eccentric shape, so single insert that flips 180 degrees to be used with either style front end. A simple insert for you can be done...let's take this to PM's.

                        Motor bolt.....250mm ....you mean the stock front engine mount? 10mm diameter? If I haven't purged it already.....I should have one......if not it went to 69Falcon's.

                          I've got a bunch of the front motor bolts from installing frame sliders. PM your address and I'll drop one in the mail to you.

                          When you say rubber chain slider, do you mean the one that bolts onto the backside of the kickstand? That is available through Hord or any of the online parts suppliers like Ron Ayers. If you mean the slider that bolts to both the top and bottom of the swingarm (on edit: not subframe), they are no longer available. However, you have a couple of options there. I know wildwhl was looking to make those, or you can go the route I did for the race bike and get a hunk of delrin from McMaster Carr and make your own.

                            I've PM'd BTT about his bolt. If he doesn't have it, I'll let you know. 250mm is the length according to the parts diagram.

                            I threw mine out hoping for a better option. I didn't know at the time they are NLA. But, it's the rubber slider on the swingarm not subframe. I would think Delrin will be better and much easier to keep clean. I'll ask WW about it.

                                frinesi2 is more likely to come up with a swingarm slider (I've placed my version or work on it way down the priority list). Also, I'm 99% certain the chain slider that attaches to the lower frame, above the kickstand is NLA.
