They aren't "crash" bars per se, but in a zero to no speed tip, with both front & rear bars, the fairing & bags will be untouched. DAMHIK  ;)

While I cannot answer your question about the caliper adapters, I maybe can offer a little insight to your parenthetical question...
The listserve is ANOTHER form of forum via email that is hosted at MicahPeak (sp?) which ALSO operates under the heading "Concours Owners Group."  It dates back to a time when TRS-80s roamed the earth and club organization was minimal and it has been kept "in business" lo these many years by donations from within the group of folks who use it.  It is populated by a few COG members and a number of former COG members.  Some of these members refuse to come out of the cave to utilize the resources available to them on the rest of the WWW (like here).  Within the group there are sub-groups (cliques) such as "Faithful COGgers," a few "Chatty Morons" ( http://www.chattymorons.org/ ) and the COG bashing ToS or "Table of Shame"-ers.  It's just ONE more venue where Concours riders and former Concours riders can come together to talk about oil, tires, and OTP.  In fact, IIRC, the listserve was pretty much the birthplace and strongest supporter of OtP.  And it was in that venue that I was introduced to and began to support OtP.  There are a few familiar persons from the internet forums, a number of other nice folks you'll never meet here, and then there are others who are less than nice.  I reckon it's kinda like any other place you put a buncha folks together... a mixed bag.

The list may go days without a post or it may have a hundred in a day.  When it has a lot, then there are folks lining up to unsubscribe.  I mean why would I sign up for an email list that might send me... GULP... email? LOL

It is NOT COG sanctioned, endorsed, operated, funded, or backed in any way though it carries the same name and is directly related to and even predates the ZG/GTR Fanatics forum and Concours.org site.
All of that said.  http://micapeak.com/mailman/listinfo/cog
Despite any claims to COG affiliation, there is none except that the aforementioned contingent of COG members still subscribe, not wanting to lose touch with those who cannot come play here for reasons real or imagined.

EDIT TO ADD:
Dear Moderators, if this is too harsh, not accurate, or otherwise improper, please feel free to tidy it up, correct it, or eradicate it as you see fit. I realize the TRS-80 comment may be over the top. ;) Thanks.

My impression after reading Rick Halls article linked to under the About COG, Online Evolution is that the Listserv was started by a COG member to aid in COG communications before any forums started. 

BTW I still have not found anyplace to get the adapters.

Back to the brake adapters..

I recall COG member zrxmopar was making them off and on, and last I remember was off due to moving, etc. Not sure if he ever got back on again.

Back a while ago I recall reading on the Fanatics Forum that there was a guy in Australia making them. He was/is a GTR owner down under. I have no idea how they compared to zrxmopar or what calipers they supported. A place to start would be to search around in the forum and see if we can find the guy.

Thats ok. My point was to chase down the AUS guy. Found this link in the Sell,Swap,Trade section of the GTR/AUS forum. Even seems to have some recent discussion.  Here is the place to start. If zrxmopar ever starts making the again I would be happy to push his product. The 6-pots on my Connie are my absolute favorite mod. there are other great mods, I enjoy sending SISF money every once in a while. But the brakes are the Fav.

Anyways, this is the place to start.

IIRC the Australia version adapters are only for the '93 and earlier, fine for those of that vintage.

I'm keeping an ear here, because I sure would like to get some for the '94 and up  :)

Yeah, I asked him about them about 6 months ago and he stated he only had them for the pre 94's.
I'm a hoping someone can come out with the 94's and up............

There's a guy who makes some nice caliper adapters for the V-Strom.  Here's his website:

http://www.svracingparts.com/

The only reason I bring this up is that the calipers and mounting between the V-Strom and C10 look very similar.  If it hasn't already been done, it might be worth the effort for someone who has both the Strom and C10 to check the fit between the two (and, of course, report back the findings  ;D)

Hmmm, Rich Desmond, Sonic Springs fame used to compete SV's for quite a while. I'll have to see if he knows these guys, might be able to get some intel.   I'm out to Bikeweek, I'll ping him but may not hear anything until I get back.

I did some digging, and found out that the SV/ V-strom calipers have the same bolt spacing as the C10 calipers.  This means that the V-strom calipers will bolt on to the C10.  I don't know whether they will line up with the rotors properly or not, but it would not surprise me if they did.  If they do line up properly, then there is a good that the Strom adapters will work.  The only issue would be that the Strom has a 310 mm rotor, and the C10 has a 300 mm rotor, though this difference should be accounted for in the fork mounting tabs.  I no longer have the stock front end on my bike, and I sold the original forks, so I can't readily do any comparisons, otherwise I would buy a cheap used V-strom caliper and try it out myself.  Again, it seems like it would be worth the effort for someone with access to both bikes to do a quick check to see if the calipers line up properly.  If that's successful then...   ;)

Vic,

I found another company selling adapters on eBay for the SV/ V-strom.  Their adapters are for Brembo calipers, but their ad states that they will fit a ZR7, as well as the V-strom and SV650.  The ZR7 uses the same calipers as the V-strom and has 300 mm rotors, like the C10, so that is another piece in the puzzle to indicate that if the V-strom caliper fits the C10, then the adapters will likely work on the C10, too.  Hopefully, that's the case.   :)

I had an email exchange with the guy who makes the V-strom adapters.  The upshot is that he seemed interested in developing something for the Concours, but the project wouldn't happen till fall at the earliest.  His company is busy with other projects right now, plus it is no doubt a small operation, plus they aren't very familiar with the Concours, plus there are always other priorities that pop up in a small business, so we'll have to see if that really happens.  Based on our exchange, the only way right now to find out if the adapters fit is to buy them.  The adapters are sold for the particular bikes they've designed them for, so fitment issues are on the buyer for anything else they might be used for, which is reasonable.

In other news, I've contacted a COG member who has a bike with the same calipers as the V-strom, in addition to a C10, and he is going to swap a caliper to see if it lines up correctly on the C10.  He is very busy right now, but hopes to be able to do that in late April/ early May.  If it fits, it would be another step toward knowing whether the V-strom adapters work. 

Stay tuned.

It turns out that the V-strom calipers are a direct fit to the later C10.  This means the V-strom caliper adapters will most likely work with the C10, but it will take someone trying them to be sure.  I no longer have the stock C10 front end otherwise I would try them myself.  Here's the link again,

http://www.svracingparts.com/products/#ecwid:category=465963&mode=product&product=1632834

You can use your choice of Nissin or Tokico calipers, the choice is made when you place the item in the cart.  The correct 4 piston calipers are listed on the product page.  So is anyone willing to give them a try?

Just to be clear, these are not an upgrade to a larger rotor like a 320mm.
This is to simply adapt a 4 pot  caliper.

The short answer is you are correct, they would not allow larger rotors.  They would only work with the stock rotors. 

Here is some more info I have.  The adapters in question were designed for the DL and SV.  The DL uses 310 mm rotors, and the SV650 uses 290 mm rotors.  Both use the same basic caliper that is a bolt-on to the C10, which uses a 300 mm rotor.  To allow the same caliper to be used on three different size rotors, the caliper mounting lugs on the fork are in different locations relative to the axes of the fork and axle.  This is why I'm confident the adapters for the DL/ SV will allow the 4 pots to be mounted to the C10 and have the caliper be located properly relative to the rim of the rotor, because regardless of the size of the rotor, the mounting lugs account for the rotor size of the given bike.  I even went so far as to make a CAD sketch to convince myself that an adapter made for any of the bikes would align properly on any of the others.

One difference between the three bikes is the thickness of the caliper mounting lugs.  This is important for this application because these caliper adapters mount to the outside of the caliper lugs in a similar manner to Shaun's adapters.  This means that unless the lugs on the SV or DL are the same thickness as the C10, spacers would be needed to align the caliper properly left-to-right.  This could be done using washers or a specially made spacer.  The spacer thickness would be the difference in lug thickness between whichever bike the adapters were designed for and the C10.  Another issue is that I've been told that the unpainted wear area on the C10's 300 mm rotors is slightly narrower than the pads on the 4 pot calipers.  This means the pads would probably wear some of the paint away from the rotor near the inner edge of the rotor wear surface, and that the first set of pads might take longer than usual to bed.  This would apply to any adapters meant to be used with the C10's rotors, including Shaun's, although some of Shaun's adapters were designed so that the pad hung out past the outside edge of the rotor slightly, presumably to account for the narrower wear area.

Bought the adapters from SVR page and Tokico calipers from GXR 600, well they fit but mounting lugs are thicker on Connie so I must make adapters, now I look for DL650 to measure the difference. Keep you posted when I am done.

What year Connie? I'm wondering if the SVR adapters will only work on 94 and after.

Mine is 2000, stock front end. I am just afraid if the caliper will seat right because there is difference in diameter of disk 300 to 310 from DL but with rough fitment so far neither rim of the disc nor top of the caliper are touching but it can be still uneven wear pattern on brake pads. I am going to play with washers to obtain correct alignment and than ask my friend to make spacers, I also need longer screws that those provided with kit to make up for difference in thickness of the mounting tabs. I will keep you posted
Wow one more thing you need longer brake hoses as caliper is sitting lower than stock. I got mine calipers from GXR with steel braided hoses so I will utilize them.
