let's keep try to keep it simple and easy as possible to make...half the beauty of the gl swap is it's bolt on simplicity and affordability...some kinda $500 custom top triple on an $80 frontend kinda defeats the purpose imo.
If it works good, it looks good...

I would need to know all of the dimensions, the look, what kind of material you guys would like, etc... in order to give a good estimate. if you guys can find some pictures of pre-existing triple trees that you all like the look of an post them on here, then I can have a better idea of what you guys want. some rough estimates on dimensions would be good as well ( i.e. offset, for diameter, steering stem hole in the triple diameter, thickness, ignition location if it is needed, gauge cluster mounting location if needed)

Here is a top tree that Cycle X offers for a CB750. Something like this would be good for me. I would prefer that the front of it stay straight across to accommodate provisions to mount the ignition switch and gauge bracket.

yup...that right there is about what I was thinking...seems like something like that would be pretty easy to drill/tap yourself for whatever gauge mounts/etc you need

I am currently in contact with member gsnorcal (Dave). He has agreed to help us design and machine some of these. As soon as I hear some cost figures and turn around time I will update this thread. Please PM me ASAP if you are seriously interested in a GL1000 top tree. The more we get the cheaper it will be.

That would be easy to replicate. If you all would like to have them made, just let me know how many are ready to purchase and I will get an estimate out to you guys.

Tagging along. 

Just throwing this out there, what about the lower triple and stem too?  Maybe tap the bottom triple for dual brake lines?

 I think it would be really cheesy to take someone elses design, and make something similar.. Worse yet if they are still selling it.
 If I made some they would A, not be the cheapest thing out there, and B, probably look CLEANER than anything else...
 Its easy to build just a triple tree, a bit harder to do a really nice triple tree...

I wasn't recommending to steal the design.  That was just an example and I knew where to grab it from.  :)

I just PM'd you.  I think you may want to thicken/bolster the design to 2-allen bolts per pinch like the Joker tree.  The tree provides better stiffness and presumably more front end stability.

 I was not referring to the Joker tree, it was showing a pic of another vendors product, and saying lets make it like that..

 
 Pesonally I think it would look pretty clean to run a slitless clamping arrangment, it would be more than strong enough for a top tree on a street bike..

 You bore the holes for the forktubes with say 1 1/2 thou clearance. There is a hole in the triple tree from the side.. say 5/8 dia that is drilled into the 35mm bore, but only about 35% intersects the 35mm bore. Then you use a 3pce clamping element in the 5/8 bore. It consist of 2 5/8 pces notched to match the 35mm radius. An allen bolt puls these 2 together, inside the 5/8 bore, binding the 35mm tube solidly.
 Take a search for Goldammer G-force fork, that is what holds them together. There is a few other ways to do it wthout the slit.
 So you can end up with a tree with 3 holes for thetobes and stem..3 side holes for clamping.. that do not BREAK THROUGH the other side...+ clean triple trees that we like..

Slitless?  Sounds like the quill clamp on Bridgeport mill or the tailstock quill lock on a lathe.  That could likely do the job.   Good idea 754!

 That is another method, but not cheap, at least one more that I think a local guy has a patent on..

 the type I am talking about is probably  as cheap to do as slitting and all the tapping..

Mec, I'm sorry to ask this of you, but have nobody I can ask to translate to English. What is the adjuster for on the fork leg clamps?

Thanks for any help, and your work amazes me.

The GDS -crown - the tensioning system for highest requirements

The triple clamp with radial clamping system offers significant advantages over all of the marketed products. In this market segment has not yet applied the method Gabelrohrklemmung make the crown from the House of GDS - Motorsport for optimal and stable solution.

Important advantage over other products: No matter what you're switching fork diameter, the GDS triple clamps you can let the bike. Only the clamping rings are exchanged on the right diameter.

Different size tension rings (all still available Upside down fork-diameter) are present.

    
The use of the fork tube gentle yoke, with the possibility of truly fixed voltage without distortion , ensures optimum driving behavior. This technology is supreme driving pleasure is guaranteed - regardless of whether on dirt or asphalt.

New activities include the triple clamps for the "youngster" in the sport. Thus accounting for most 80cc motocross kids (with upside down forks) as well as available to do all the "big"  GDS triple clamps.

In early 2004, the completion of the development and production stage of the GDS triple clamps more and more a reality, mainly the fact that talented racers longed for a development that is tough and uncompromising demands.

If you already setup your fork several times have changed and you still are not satisfied, keep in mind that the series crown may not be as accurate as it should be. We have seen on many measurements (various brands and types of on-u.Offroad), that the tolerances were enormous. By rapid mass-production series triple clamps were partially processed so that forks just do not curse ended and could not play to their full potential. For more expensive forks, which are often equipped with very thin-walled tubes fork (weight), there is the tension to the clamped side yokes. Our precision CNC machining and radial clamping pliers, we conclude from this shortcoming.

Here you see an original fork bridge (built 2007 MC 250 four-stroke with 20 Hours,). Based on the print image you can see how stable the front forks, despite 2.3 kpm torque (the manual says). The upper bridge is stuck the fork in the lower bridge, it can not be stabilized by clamping the unilateral really, because a 360 ° Power is not given.

 



 

 

Here you can see exactly how our radial clamping system is set up:

Green arrows: the direction of tightening     

Red arrows: conical ferrules tighten the fork tubes evenly (360)

 

 

( 1 ) The GDS -yoke is made ​​of high quality all-aluminum CNC-machined. ( 2 ) High quality plastic conical rings radially clamp to clamp the fork tubes without you (as with conventional triple clamps which clamp only on the screw side and push the fork tubes oval). This improves the starting torque of the stanchions. ( 3 ) Made of high quality CNC machined Vollalu clamps give the conical rings with the necessary support. These are with a special key (included here) tightened. ( 4 ) steering stops adjusted to any Motoradtype.

 Special tool for assembly of GDS triple clamps (included here)



 

The GDS have anodized fork bridge you can in the following colors:

STANDARD COLOUR: Anodised Alufärbig (icon photo)

 

OPTIONAL COLORS (extra charge):

Gold, bronze, royal blue, steel blue, red, titanium, orange, black, green. The rings are anodized alufärbig, please request for special requests.

Example photo of the  GDS triple clamps, optional colors: no rings


 

 

As years of engineering companies, we draw important and experienced knowledge, technology and know-how that we can use to 100% in motorsport. Thus we are able to take care of ourselves too much with the interests of our customers.

We work with several teams in the on-u.Offroadsektor closely together, as the crown by the excellent, sophisticated system in almost all areas of motorcycle racing ideal conditions and better results, both the result and in the maintenance achieved. Of course, flows and our whole experience and expertise in our new Street Fighter crown.

_no loose screws
_kostengünstige production
_no bracing of pipes
_genaue fit the bridge
_High life
_extrem fixed Matreial
_schönes design
_rennerprobt
_Simple assembly
_no wear of the screw heads

GDS triple clamps SETUP (offset):

Are you (a motorcycle steers by itself or will not turn easily, etc.) with your original setup Crown unhappy, we offer you completely customized to your desires to drill holes (setup) of the steering tube (thorn). We know the problem with adjustable (eccentric) Clamps setups that can be twisted easily (dropping, etc). So we offer this solution is not to. You have the possibility to order the offset on your own particular level. For the workshop, we offer the GDS -fork bridge as a "blank" on. Of course, all the parts you need here including special keys.

The graphic and key rings without


 Closely associated with various drivers and teams are always there with suggestions that may lead to improvements. So we were able to design changes, partly by design changes, partly by suggestions driver, a much longer service life and lower weight recorded, compared to conventional triple clamps.



Due to the many positive feedback for an end to innovation of our products and our company's development is not in sight.



DELIVERY:

the GDS -crown consists of: upper and lower fork bridge with all the associated clamping elements with the special wrench (to fit to your fork tube diameter) adjustable steering column (spine) of high-strength aluminum steering stops, handlebar mount (arm mounts) in position and height for Motocross , Supermoto, Street Fighter to remodel and all the normal link on your bike. Super athletes use their existing rail links.

The product range also includes niche areas such as caliper adapter and steering stops, enrich our product line and fill in the motorcycle market.

We are constantly working on this page, you should have any questions, you not afraid to ask us. The GDS team will help you in solving your love problems.

 Man those got to be pricey, nicely made.. I remember a chopper company using that setup around 15 years ago.

My buddy that makes the custom front end did some testing, I think the slitless we call camlocks(i desribed the cocept above)  held better than a single bolt triple tre on their application. The other type they developed, is stronger than that.

 If I do run slits, I usually run them within the tree, like Ceriani does, much cleaner than to the outside.

 Dontrefer to them as 80 dollar forks, look at them as an improvment, and when you change out a part, strive for better function, if possible...

totally agreed 754 but the cool thing is that the gl swap is an improvement but you can do for $80...these fancy triples are gonna cost a lot more than I can afford

Thank you Tweakin for the translation!

Has anyone used a 1" flat or slab top tree for the GL front end conversion? It would seem to me that because there is a 2cm difference between the steering tube clamp height and the fork tube clamp height on the stock Gl top tree that this difference should be maintained if I want the ends of the fork tubes to protrude above the top tree. Am I not thinking straight?
