I was having a real hard time spending over $200 for a new sensor and decided to do some digging and found KTM uses the same brand TPMS sensors as BMW, Schrader. So I bought a "KTM" TPMS sensor from Rocky Mountain ATV for $59.25 and what do you know it works perfect, KTM part # 61412033000. I can't remember exactly how I found the sensor on Rocky Mountain ATV, their part search doesn't seem to find it, so find it by going to go to OEM parts>KTM>2019>Super Duke GT>Rear Wheel>#35, here's a link OEM Parts for Motorcycles, Dirt Bikes, ATVs, and UTVs | Rocky Mountain ATV/MC Of course you can source the sensor from any KTM parts seller but Rocky Mountain was the cheapest I could find and have free shipping over $75. KTM's full MSRP is only $77.96 so it's a deal no matter where you get it.

This is the new style smaller sensor so you will need a different bolt if your bike has the older large style as my 2016 did, I didn't do this so had to improvise a little and fabricate the correct size bolt. I'm not sure but I believe the bolt you will need is BMW part # 36318359961, $9.30 So if you want to keep a little more cash in your wallet and don't mind the TPMS sensor having a KTM logo give it a go. Here's a couple of pictures, the last picture is what I believe but have not verified is the correct bolt. Oh I almost forgot the new sensor comes with a sticker with the ID code so no wake up tool needed!

@mmroadster , Thank for the post. Couple of questions. If these aren't made in China then where? You write your '16 has old style TPMS; I wasn't aware there had been a change; can anyone verify when? Best I can tell is the sensors for ALL the 'standard' wheels is the still the same. But the sensor for the forged wheels is different. I can say the bolt p/n you reference is the same one that has been/is used since the K1600 first came out (standard wheels).

In summation, best I can tell there different sensors/mounting bolts for standard and forged wheels.

FWIW, you can search for Schrader TPM sensor fitments here: Schrader TPMS Solutions

Searching on the K1600 suggests that there are three variants: 2011-01/2017-12 Bolt In; 2011-01/2017-12 Valve Mounted; 2018-01/2020-12. While the OE Ref# is different for all three, they all resolve to the same "Aftermarket Sensor", part# 3141M.

Another FWIW, is that the "Aftermarket Sensor" for the KTM 1290 SUPER DUKE is listed as part# 3142M. Before anyone asks, no I don't know what the difference is!

A google search for "schrader 3141M" turns up multiple supply options, all around the €55 - €60 price range.

Hey Gunnert the sensors are made in Italy.

As far as new vs old style I'm not sure when the change was made, I found this thread when researching that shows the new style sensor and mounting options with part numbers. Winkelventile der Speichenfelgen der R1250GS an R1200GS LC Speichenfelgen nachrüsten? I've included translated screen shots of the relevant posts.

I then took the part numbers and continued to research and found that part number 36318567683 aka 8567683 was superseded by 36319832032 aka 9832032

Then going to the Schrader website, Schrader TPMS: Code:9832032 - Schrader Motorcycle Gen 2 BMW (stem or b shows that part number as the Gen 2 BMW sensor.

So I can't be 100% sure that bikes are actually coming off the assembly line with the new sensors but I think it's fairly safe to say that they will be and all future replacements will be using the Gen 2 sensor.

st13phil the Schrader website is what got me thinking again about a KTM sensor. I emailed Schrader asking the difference between the 3141M and 3142M but I didn't receive a response, my guess is the only difference is a KTM vs BMW logo. When I still had my K1300GT I picked up a used KTM sensor to try when the sensor in my rear tire started acting up but traded in the bike before I installed it. Thankfully I kept it and before ordering the new KTM sensor I tried successfully to sync it with the K16GT.

Just an update, the KTM branded sensor I put on the rear wheel last year is still working great. The original BMW sensor on the front wheel is giving out this year so I ordered another KTM branded sensor. The best price I could find this year was through www.ktmpowerhouseparts.com $69.99 with free shipping. I also ordered, as mentioned in the first post, what I believe is the correct screw for $14.74

from A&S Cycles.

KTM sensor on the 2015.

My TPMS sensor, or the bolt rather, does not have a schrader valve. As shown above, mine is different. Mine mounts like the one in this video.

The stock bolt (I bought a new one from MAX BMW) as shown in that video has a larger diameter than the inside diameter of the KTM sensor. I've not yet dismounted my tire but after I do I'll determine whether to mill a little off of the bolt or mill some from the sensor. My opinion at the moment is to mill the bolt, but I'll know when I get more time. I've been extremely busy with work and my bike has taken a back burner for now and into the next few weeks.

I opened up the sensor diameter. Did not want the bolt shearing when tighting it or trying to remove it sometime down the road.

I can't remember what the heck I did before the invention of tire pressure sensors. All of my other vehicles are so old they don't have them. I get scared every time I start to drive or ride one.

I'm a little confused about what you guys are saying, I just received my new sensor and bolt and they seem fit together perfectly. I have not installed them yet but I can't foresee a problem.

The shank (unthreaded part) of the bolt would not go completely through the hole. I had to use a dremel with a very fine cone-shape grinding wheel and ever so slightly enlarged it. Bolt when through perfectly. I just installed it. Bike cleared the red line but not reading the pressure at the moment. I hooked up my GS911 and it is relearning the rear sensor as I type this. Will know more shortly.

Edit: Using the GS911 (it recognized the sensor immediately), I had to manually enter the sensor ID number, then do the "learn" function. It took about 2 seconds for each. BOOM! It worked!

As a side note, I'm currently using the new style sensor in the front wheel (like the one pictured here), and the longer old style sensor on the rear wheel. After a very warm 4 day ride this weekend I noticed that the new sensor compensated for the heat build up better. I started the days at 41.6 on the front and it never went higher than 41.7. The rear would start at 42.1 and got as high as 44.1 during the day. I know that the rear tire works harder and builds up more heat, but this was interesting. The results were same running on straight roads or charging through the hills of SE Ohio.

How sure are you that these are NOT Chinese?

It's my guess that they're made in China for Schrader, just like my reliable iPhone that was made in China.

Your odds of guessing correct....

The packaging is marked made in IT, which I believe is Italy. The first sensor I bought was in a box, now they ship in a bag.

A quick question to Siri about country abbreviations, led to abbreviations.yourdictionary.com which lists country abbreviations by continent. Italy is indeed IT or ITA depending of 2-letter or 3-letter. I don't know about Italian manufacturing. Some of their cars

, others

.

Which bike shows the 10ths digit on the TPMS? I have never seen anything other than whole digits on either of my GTLs.

I agree, my only reason for stating these are not made in China is because many people have had Chinese ones show up DOA.
