New type of TPMS transponder

[CrashGordon]

I've been having the low battery issue for on my TPMS (both front and rear) for a while now so I had them changed under warranty when I had it in recently. When I picked up the bike, the service manager handed me my Murph's 90 degree valve stems and told me that they would not fit on the new transponders. That was news to me. Having to go back to straight valve stems is a royal pain in the arse. Please tell me someone has or is working on 90 degree valve stems for the new transponders!

I carry a air chuck with me , cheap , no problem.

[VirginiaJim]

Didn't we have a thread on that?

[CrashGordon]

I saw a thread talking about Kawi switching to the new transponders, but I didn't see a mention that the valve stems wouldn't interchange. Perhaps I missed that. I'm just really bummed that I lost my 90 degree stems and would like to get them back by next tire change.

[VirginiaJim]

For Sale section?  Yet another reason not to go with the new ones...

[CrashGordon]

Sorry, I guess I haven't made my question clear. Has anyone heard if there are 90 degree stems available for the new transponders? And unless everyone is already aware, your old 90 degree stems from Murph's will no longer fit. I wasn't even aware that Kawi was changing to a different brand until they were installed. I've been away from the forum--i had an accident about a month ago and the bike has been under repair during that time. I had the transponders changed because it was a convenient time and my old ones were malfunctioning almost every ride--even in warmer temps.  I thought someone with more insight than me might be aware of something in the works or knows of a source for compatible 90 degree stems.

[VirginiaJim]

I don't think we've an answer for that, unfortunately.  Do you have dimensions of the new one?

[gPink]

Did you keep the old ones?

[Rembrant]

Did you keep the old ones?

Good question! I'd spend $20 on having new batteries installed in the old ones, and then sell the new ones on Ebay...lol. That solves the problem and earns money at the same time;).

[CrashGordon]

I do not have the old ones. Not sure if Kawi would have replaced under warranty without keeping them. I do not have the tools nor the space to do this kind of work on my own, so pulling my own tires off and replacing batteries was not an option.

Just hope someone resourceful is working on replacement stems. If so, you're about to have a market since all new bikes are coming with the new transponders.

The new transponders don't have a removable valve stem. They mount by pulling through from the inside. The old ones mounted by screwing the stem into the transponder from the outside. I don't think you are going to be able to put 90's on the new ones.

[B.D.F.]

Yeah, what he said.

The other unfortunate thing is that these new sensors are potted, meaning the entire sensor if filled with liquid epoxy and it makes changing the battery close to impossible, unlike the original sensors.

That said, I have high hopes that these sensors will work better than the originals. These are also coming from an entirely different company; the originals were made by LDL in France, the new ones are made by Schrader (sp?) in the US although I am sure in the end all were / are made offshore.

Do you know the Schrader part number?

[B.D.F.]

No but I do not believe it is a part you can get from Schrader (sp?) anyway. It is almost certainly proprietary, unique to Kawasaki, and only sold to Kawasaki per contractual agreement. Again, I do not know this to be the case but this is the way these things are usually done and all manufacturers typically use this method to assure they are the only source for 'their' parts.

A possible solution to the OP's problem  is a 90 degree screw-on extender, assuming the new stems accept a standard threaded cap.

HA!!
Stop worrying about these things!!!At least that is what i do!!!
try this stuff:

and if you like then you can still fix the tyre sensors the next tyre change......!!!

That sounds very similar to the ones on my Nissan. The batteries are good for about six years and then the whole unit has to be replaced. And you probably won't get the old ones back if they are replaced under warranty

That's silly. Why would we want to carry a TPMS device when one is built in to our moto?

Well, they have a mountable display model too.  For the cost of replacing one Concours sensor, you can have a whole monitoring system that requires no more tire removal and no more future costs outside of easily replaceable lithium batteries.

I wish we had an option to throw away our current sensors and have something that would feed the data from these types of sensors to the existing Concours computer so we can use the built-in display.
