kamlooper Posted August 20, 2011 Share Posted August 20, 2011 decided to switch to metal valve stems rt1100,shorter than originals easer access,nice with rubber gasket both sides,they fit right in,$5.00 each from local tire shop. photo bucket Link to comment
BerndM Posted August 20, 2011 Share Posted August 20, 2011 I've thought about doing the same thing with my next set of tires. Seems odd that the front wheel (05 RT) has a factory installed metal stem IN THE SPOKE pointing off the side. This is GREAT! Makes filling and checking very easy. Why they didn't do this in the rear is beyond me. The metal stem I will install in the rear will be a 90 degree angled one, for easy access. Link to comment
cruisin Posted August 20, 2011 Share Posted August 20, 2011 the guy who changes my tires, started carrying them and installs the chrome plated ones in straight and 90* for 5.00. I am letting him switch all of mine over to the 90* as each tire gets replaced. Link to comment
TomBarnhart Posted August 20, 2011 Share Posted August 20, 2011 What diameter size are the stems for a R1200R??? Ready to change tires and want to get them before mounting the new rubber. Link to comment
cruisin Posted August 20, 2011 Share Posted August 20, 2011 I'm thinkin' all car and motorcycle stems are the same size. I'm sure some with more knowledge than myself will chime in if that's incorrect. Link to comment

Nope,several different size valve stems are made. Make sure you get the correct size for whatever your application. JR356 Link to comment
cruisin Posted August 20, 2011 Share Posted August 20, 2011 see what'd I tell ya. I guess that applies to diameter as well as length? Link to comment
Tech1 Posted August 20, 2011 Share Posted August 20, 2011 I put in one of these (silver) with my Tiregard TPMS. Works great, aimed to the left (muffler side on the RT). Very easy to get to and trust it more than the standard rubber stem with the weight of the TPMS sender. It seems a little lightweight for the TPMS, I am watching the threads close, but no problem so far. Biggest problem is that I dropped and broke the lcd monitor! I will probably order a new one during the off season. Link to comment

kinchy Posted August 23, 2011 Share Posted August 23, 2011 Had them on my tires, (sold at the dealer) although I can't support it with any scientific fact the weight of the stem extension after a 4K miles caused the rubber to tear (supporting the extension at the base) and enough loss of air to shut me down 70 miles from home. Tire repair kit (although used as a wrap) worked fine. Maybe it was unrelated.. but it's never happened again since I removed them. Link to comment

topdal46 Posted August 27, 2011 Share Posted August 27, 2011 I had the rubber valve stems on my R1100RT, riding along one day, rear tire went soft/flat on the freeway. Lucky I was close to home, valve stem was broken/cut. All the air escaped. I replaced the stems on the bike with Metal. no problem since Link to comment

BMW MODEL SPECIFIC ISSUES: EXCEPTION: 1999-2007+ BMW K1200LT, All R1150RT: NO, OR NOT WITHOUT MODIFICATION. BMW created the front wheels for the K1200LT and R1150RT with a very narrow surround around the hole and recessed that surround. To fit our valves to these wheels, you would have to dremel (grind back/cut-off) the flanges on the valve body as shown the examples below: - pictures of the K1200 issue: K1200LT Stem Area, and Valve Compared to Stem Area. - the modified valve, dremelled back to fit, shown on an 2004 R1150RT (pics coutesy of Perry DeWitt): Front Valve front view, rear view, side view. EXCEPTION: BMW R1200GS (Tubeless Street Wheels), certain other R-series with cast-lip wheels (modification required): NO, OR NOT WITHOUT MODIFICATION. BMW's center-line ridge on the wheels makes the space for the valve too narrow to fit without modification of the valve body, which can easily be dremelled back to compensate. Please view this R1200GS (cast wheels) modification image by Jim Von Baden for an example of the modification (tool: dremel, cut-off wheel. Time: 3 minutes). Note: Does fit OEM R1150GS wheels - Picture (credit: Jeffrey Hagen). EXCEPTION: BMW Wheels with TPM (Tire Pressure Monitors) integrated: NO. - These will NOT work, you MUST use the BMW-TPM specific valves. They will fit K1200/K1300 that are NOT using the TPM system: Photo of mounting on '08 K1200GT non-TPS wheel (pic & fitment info courtesy Erik Miner) This from the above THESE link in the FITMENT: section. I have one on my 03 RT. Link to comment
macx Posted August 28, 2011 Share Posted August 28, 2011 Yes, by all means, a link or a name or vendor or whatever! I just got new tires but will likely need another set by next spring. Been looking for something like that. Link to comment
RedMac Posted August 30, 2011 Share Posted August 30, 2011 Then, there are also THESE I've been meaning to order some, but haven't yet. They look great. I was impressed reading their web site. However, so far they aren't impressing me just based on the attempt I had to get customer service from them. Their web site only lets you order two valves. However on the RT, you only need to replace the rear valve. I emailed them about ordering just a single one, never heard back. Nada.. nothing.. no reply. If they can't even answer a PRE-sale question, I would think their POST-sale support is even worse. Link to comment

The reply is, "You can't buy just one, buy TWO and keep the other for a spare in case the stock *metal* valve on the front wheel breaks". I doubt that will happen... I don't need 2, I just need one. Why should I have to pay for a second when I only need one? Sorry.. I won't be buying. While I can understand the need to simplify the sales and shipping process, the reply denotes a lack of understanding of "customer service", instead the attitude is "My way or the highway". Too bad too, it does look like a nice product. Link to comment

bobbybob Posted September 5, 2011 Share Posted September 5, 2011 Armando, My R12GS uses 10mm and I read somewhere that BMW's all take the 10mm. I hope that is correct! Link to comment
Dirtmerchant Posted September 5, 2011 Share Posted September 5, 2011 I bought a set of these in Silver about two months ago, used one, the other is still in the box... I'll do $22 shipped to you in the ConUS Looks like a factory part :deal Ariete Racing Valve Stems Aluminum 90 degree valve stem with caps Air valve will not open at high speed Made in Italy Weight 12g Sold as pair Link to comment
bobbybob Posted September 5, 2011 Share Posted September 5, 2011 I personally don't like the above stems because the nut that secures it is *inside* the wheel, so that if the stem becomes loose thru whatever reason, you will have to demount the tire to re-tighten it. I mounted some with the external nut and had them nice and tight at first. A few weeks later while adding air, I accidentally rotated the stem some because it was no longer "nice and tight". I guess the rubber washer flattened out a little and the tension decreased. It was easy to re-tighten it being external. If the nut had been inside, then my moving the valve back straight again would probably have loosened the underside nut even more. Thats why I said above "they are better". YMMV. Link to comment
drswift Posted September 7, 2011 Share Posted September 7, 2011 I've used these for 4 years on two bikes with no problems, just a little more balance weight. They are cheap enough to use new ones with every tire change. Patchboy 90 degree valve stems Link to comment
randy Posted September 28, 2011 Share Posted September 28, 2011 I have also used the patch boy valve stems. Very nice units, and they have worked great for me. However as noted on some BMW rims with the "center lip" grinding was necessary. Link to comment
Selden Posted September 28, 2011 Share Posted September 28, 2011 I'm probably being overly cautious, but given the reported fragility of the R1100 3-spoke wheels, I'm loathe to file away any of that center reinforcing rib. Paranoid? Link to comment
randy Posted September 28, 2011 Share Posted September 28, 2011 well I am guessing less that a 1/16th is needed, also you can file the actual valve stem. basically just file the two sides just lightly and that works. of course then the valve stem is not as nice looking a little steel wool, some primmer and a couple coats of matching paint and it looks great.

Norm 88 Posted September 29, 2011 Share Posted September 29, 2011 I am using the Ariete Valve Stems,on My 1200 RT, they have an O Ring on the top and inside of the Rim. The thread's are on the inside of the Rim...The threads' have a locker sealent on them no problems' in 40,000 mi.Still good and tite.... Link to comment
