History and product up-date on KTM/Caponord 19/17 tubeless wheels
a brief history,,,,
the notion of having genuine tubeless wheels/rims has intriqued many over the years as evidenced by the variety of ways that riders and manufacturers have adapted to achieve that end,,,,we could break their efforts down into four main genres,,
Group A...those that try to seal traditional wire/spoked wheels,, it is the older of the groups ,,,,the methodologies/techniques utilized by these questors has ranged from a variety of sealants and application techniques with and without vacuum assistance ...everything from numerous layers of electrical tape,,,silicone sealants ,,,low and hi-end exotic epoxies,,,special single and double sided adhesive rubber bands and carpet tape,,,sealants protected with nylon strapping tape and/or kevlar/carbon fiber impregnated strips,,,rim bands glued on with rubber cement,,gorilla glue,,,,large O-rings on the outer bead corners ,,,,often unwittingly performed on rims never intended for tubeless tires....some techniques work better than others, some hardly at all,,,alot has to do with the care in applying and cleanliness of the sealing area not to mention only sealing rims designed for tubeless application,,,,and YES i know major manufacturers that routinely seal ANYthing.....most of these technigues are price conscious,,,,and others will run you several hundred dollars for the sealing kits,,,,
the biggest drawback is that at excessive speeds above our national mandates circa 75-84MPH,,,one moves into the territory where centrifugal force has a tendency to want to sling off the sealants,,hey it's basic physics....and what happens if a spoke breaks,,,,these are the main advantages that the next goup has over this one..
Group B,,,those that provide the motorcycle public with wheels /rims specifically made to use tubeless tires on them,,,that quest has burdgeoned in the last 30 years,,,,,some examples are Honda's Comstar wheels in the '70-80s,,numerous cast and forged wheels of every description,,,,,
and in the last 15 years,BMW,Aprillia/caponord,Moto Guzzi and a few trials bike Mfgs have offered wire wheels assembled with specially designed tubeless rims whose spokes attach from the outside edges of the rim in a x-lace pattern to the hub,,,commonly referred to as tubeless x-laced wheels...BWOE the techniques differ only in where the nipple is located,,,BMW with the oldest patent runs the spoke thru the rim's edge to the opposite side of the hub where the nipple is anchored and adjusted,,,the others reverse this process,,,their nipples are in the rims edge,,,,the trials folks have rims with a special rib running down the center of the rim,,the spokes thread thru and are adjusted in the hub ala BMW,,,,,
these wheel assemblies range in price from $250-1300...most are in the $350-450 range,,,,he BMWx-laced wheels are all circa $950-1300each the caponards/moto-guzzi not much less....hit something and bend them and you will need a specialist to repair them,,,Yes,,they can be straightened more often than not,,,,
Group C,,, is what i call the new hybrid technology,,,where a variety of mechanical techniques are utilized to seal the nipple in the rim...the Alpina company,,spoke and nipple suppliers to the bicycle/mc kingdom for 80 some years,,have bought practically every patent on the planet that deals with any notions surrounding sealing a traditional wire wheel in this manner....
some years ago i designed a special sealing and locking nipple waiting for the ''right time '',,,although different than anything alpina has,,,the ''idea'' of mine bangs into the ''idea'' of what they own from what i have gathered in speaking with them,,,,,we'll see if we can collaborate,,,you will see this technology spread in the next few years....several mainstream manufacturers have already bit into their apple,,,
Group D,,,is largely composed of folks that cross-pollinate existing tubeless rims from certain brands /models and make them work on other brands/models,,,BWOE the numerous transformations available for the BMW GS/HP-2 crowd,,,,converting these models from touring to mega-moto to off-road to....even better offroad/competition...Baja-1000/Paris-Dakar specials.....or..
from brand to brand ala taking the 19/17 36hole tubeless Aprilia Caponord rims and x-lacing them to oem KTM or aftermarket RAD hubs on the LC-4/8 Adventure models,,,voila,,,now a KTM adv rider has all the benefits of genuine tubeless tire specific rims,,,,their merits have been posted too numerously already,,,
that's it for today,,,,will post phase two of what it took to create these and the lessons learned along the way,,,:thumb

These wheels look like exactly what I want!! I want a second set of wheels for my 06 KTM 625SMC.
1. Do you know if the front brake calipher on the SMC would clear the spokes, as the SMC has a 320 mm front rotor?
2. If so, how much to build a set and ship to Calgary, Alberta?

What are the problems with Caponard and BMW x-laced wheels???
what are the problems with caponord or bmw tubeless x-laced wheels
as cut n pasted from this thread 'ask woody about your wheels''
<hr style="color: rgb(87, 87, 87);" size="1"> <!-- / icon and title --> <!-- message --> [quote=DakarBlues]Hi Woody,
is the CapoNord rim set free of any problem when set up for LC8 hub?
we have had no problems attributable to the building/lacing of these rims to any LC-4 or LC-8 hub....i sleep better when i lace the rear wheel with the billet hub from RAD...i had RAD build this hub with extra beef in the areas where spokes go through the sprocket side lugs,,,there's considerably more stress placed on those lugs when the spokes have to cross all the way over to other side of a wide rim,,,specing that hub with 6061-T6 over the oem casting didn't hurt either.
An inmate some time ago told of problems with the wheel consistently falling out of true every so often.
we have built 50 sets of these wheels since the prototype set was built for that particular inmate,,,not one person has reported any problems with his/her wheels,,nor has anyone sent one back for re-truing,,,what we have ascertained is that the Caponord rims as well as all of Bmw's rims that were built by Behr have a QC problem..all my dilemmas arrive in the area where the rim is butt welded together and the associated hand grinding to very loose tolerances,,,the Caponord rims are slightly worse than the BMWs.....
this is the region that i was being slammed for...the rim width internally as well as externally routinely varies between 1-3mm/.040-.120'',,if you make one side perfect well then the other side will be out of wack,,,it was in dealing with this customer's flak that we found the cause of the readings,,now we just split the reading so that territory looks like an hour glass centered on the rim...amazingly i nor anyone else can tell that there is this quirk in the rim,,we have on occasion put the finished wheel in the lathe and machined a bit of the protrusions just to ease my eyeballs.
Is the BMW rim having the same problem?
yes,,,the rim also has unusual divots that vary between.015-.080'':cry,,anything over.030'' we recommend filling with JB weld and machining to less than .010'' circa $30-50 depending how big,,,,FYI some of these divots are close to 3-4'' long,,,we always use the inside bead to do our measurement laterally and longtitudinaly...using the outside is a joke
Is the BMW rim free of that problem?
not yet,,,however i've learned to work with it and routinely get both the Caponords and BMWs coaxed into circa +/- .010'' run-out....i've been told it's damn difficult to make chicken soup out of chicken-shit ,,truth be told i've transformed many a clunker into a very useful unit again,,,hey!!isn't that why spices and perfume were invented???:wink:
Is it possible to anodize the BMW wheel orange or Blue?
we can do most anything to anything you've got...:super
My bike is a 2004 Adventure S (Go!!!!!!!)
well ya have good taste in your bikes at least:thumb
I really like the CapoNord piece of art!
it's grown on me too,,,be forewarned we routinely get complaints from customers that get mesmerized with our product and BWOE place them on their coffee tables in the living room ,,develop drooling attacks,,eye fixation problems accompanied by an occasional un-expected woodie ....we are getting kind of concerned over here to the point of recently discussing these symptoms with our insurance agent....those of you who have experienced these symptoms please chime in and offer your advice...
That's what i love about this forum..the camaraderie and willingness to help each other out...:beer
625SMC KTM with Caponord genuine tubeless rims and 320 mm disc ..DoAble!!
2,, circa $2500 with billet hubs $1700 using your wheels/hubs,,,S&H circa $100-200 depending on speed
Woody, what width is that front and rear rim? Cheers
EDIT: Just found answer here!! See some of us can actually use the search thingy!
