What if any ae you doing that have run the XB forks in tuber triples doing about the diffrenece in the spread of the triples between the XB and tuber? I don't want to have to push the tubes through the upper triple an inch or so. | ||

i know phelan ran them in tuber triples. part of the issue is the adjusters stick up too far. | ||
| Blks1l |
Thanks, I actually got his front end, but he had the tubes pushed up though the upper triple. It was for an S2 which had the clip ons mounted up there. I don't want to do that , because I didn't want to lower it that much. | ||

I had the xb forks in my tuber triples and the only real way to make them work is making the stick out the top which I did not like. There is a guy on buellxb.com I think his user nam is ophawk or something like that that made a lower spacer and it seamed to work well. Dont remember what he usef for a stem.... | ||
| Blks1l |
Thanks Purpony I hadn't thought about that, I might to have to look into a sportster stem and see what kind of dimensions they have. | ||
| Purpony |
looks like i was wrong... he used XB triples, but since the XB stem is longer, he used the spacer to make the neck longer.  I used the XB triples as well but i did a little counterboring to them and used an X1 stem..... Now this has me thinking..... what if you where to use an XB stem with Tuber triples and a spacer???? Never though of that, and i gave my XB stem away... so i cant even measure it now, lol | ||

what a simple solution, what thickness is that spacer ? | ||
| Blks1l |
I am definitely going to look into that. Thanks | ||
| Purpony |
i forget off the top of my head, i had it all figured out at one time. The problem i was running into was the spacer needs to hold the bearing, I designed one up on my RP machine and made a plastic prototype, but to be there was not enough meat on the spacer to hold the bearing.... before i could really look into it further i just pressed the stems out and swapped them. was much quicker and easier. | ||
| Guell |
yep, thats what i plan on doing is just swapping out the stems. | ||
| Purpony |
when you swap out the stems though, my X1 stem in the XB triples was to short. Thats because the X1 lower has a counterbore, and the XB does not. I counterbored my XB lower and then pressed in the X1 stem and it bolts on like factory now. Also, the XB upper is held on with a nut, the X1 with a bolt. I bolt head it to large to fit into the XB upper, i may of been able to find an allen bolt to fit, but instead opened up the upper some to, which allows the X1 bolt to work.... XB lower triple (bottom side) after i counterbored it  XB upper triple (top side) after i opened the existing counterbore to accept an X1 bolt  (Message edited by purpony on January 19, 2011) | ||

So when you use the XB triples with the tuber stem, there is enough offset to pickup on the proper mounting points on the fork tubes? I see that the XB bottom triple does drop down but it doesn't look like that much. I thought I have read that the XB triples pull the forks back further then the tubers, and will reduce the turning radius is this true? Also thought I read that there is some type of interference with the top triple, and frame. Thanks | ||

there is just enough space between the upper and lower XB triple with the X1 stem to work. If the XB forks where not tapered like they are, there wouldnt been any of these issues, lol. The XB triples do play with the front geometry some. I have never ridden my bike yet with the XB triples, but others have already do it and say the effect is pretty minimal. It is also true that you loose turning radius in a tight turn. My issue is the top triple now hits the tank before it reaches full lock... not the end of the work, just means it will take some more time to turn it around in the garage. I am planning on making a couple standoff fork stops so i prevent it from hitting the tank all the time. | ||
| Blks1l |
What exactly hits the tank, is it the handlebar clamp portion? If you had the R type with the handlebars mounted on the front of the triple would there still be interference? | ||
| Purpony |
the upper triple itself hits the tank | ||

Here is explanation of the spacer! http://www.buellxb.com/Buell-XB-Forum/Buell-X1-M2- S3/help-xb-wheel-conversion | ||

The pinch bolts on XB triples are on inside, while they on tuber triples are on the outside. From my understanding, that's the main reason for the interference. | ||

How about an X1 lower with stem and an XB upper? Would that combination work? | ||
| Purpony |
Wow... old post! No, can not combine Tuber and XB triple parts. The offsets are different. Thats why you lose steering radius when you run XB triples on a tuber. I ended up designing and machining my own billet triple. I'm now running 1125 forks so my triple tree has the correct 1125 spacing with the oem tuber offset. Works great! |
