TPMS out, 90deg valve stem in
« on: February 02, 2019, 12:22:36 am »
2016 C14

Some time ago I read a post(s) regarding replacing the TPMS sensors with Honda Goldwing 90deg valve stems
I intend to replace mine eventually and send my sensors to Harry Martin for his continued research
Pictured are 11.3mm MotoD's

Do these later model TPMS's and the Kaw inner wheel make a standard valve replacement difficult?
Other than 8.3mm or 11.3mm through rim?
Anybody out there with some input?
Thanks

This is what a Colorado Kaw dealer uses for TPMS replacement valve stems, $8.00 each (pic shows a 4-pak)
According to the spec's, it fits a .453" through-hole in the rim assuming the stepped o-rings fit in and around the rim through-hole
I read in the other forum that this elbow style tends to flex, to temporarily leak at the orings, when you push on the air chuck when filling a tire
I don't know! It sure would be nice to hear from someone who did this replacement
The Moto D looks quite stout, lower profile
And it looks kinda' cool

From the website:

Size: 11.3mm (0.453in): Fits all Suzuki, Yamaha, Kawasaki, and Honda Motorcycles with an 11.3mm valve stem opening (except Honda GL1500, GL1800, BMW R1150RT 02-04, BMW R1200GS 04-12, BMW K1200LT 99-08 , BMW K1100RS/K1100LT 93-96). Fits KTM RC 390 (2015+).

So the question is, what is the valve stem opening on a 2016 C14?

It seems to me I had read that these will fit one of the TPMS styles we have, but not the other.  I'm thinking it was the early type TPMS, but not the new version.  Hopefully someone else will come along with something actually useful, unlike my post.   :D

I'm guessing the 11.3mm,, as well
Could the tapered, conical seal be an issue, unique to this later model TPMS and the later model rims?
The older TPMS doesn't have that style seal and it appears to be 8.3mm
Hmmm!

Would guess the larger of the two...used to be that the smaller diameter hole was on most European bikes...and the larger diameter hole was on everything else...DAMHIK...let's just say a late night filing session got the larger diameter valves into my 1986 BMW K100RT rims... :beerchug:...

That tapered seal is interesting, though...

But, the fact is...on any C-14...I don't know...

well, seeing that the only Kaw OEM sensor in those pics, is the "old style" one,
and combined with the fact the rims themselves have not changed, other than Paint/color, and also the new style potted units are used to replace old style ones..

I would have to say the "flat washer type seals" will accomplish the task.

Here is my old 2008 C14 front rim (in silver) I forgot I had it sitting around
It's a .453 (11.5mm) through-hole, c'bore .75 (19mm) resulting in a .156 (4mm) wall
It accepted the "old TPMS", pictured with the spring in previous post

Then here's an internet pic of a 2016 C14 rear (in black)
A different inner wheel cross section but with a similar through-hole, counterbore and outer rim  feature, it appears
It accepts the newer "Kaw TPMS" as pictured

The two TPMS designs are different

So far, I don't see why a 11.3mm wouldn't work but I sure would like to find the old post where someone experienced something different

 :rotflmao: :truce: ;) ;) ;)

as I noted, the physical dimensions are the same, it just throws you off doing a comparo of front and back rim innerds... the sensors are interchangeable... dimensionally  those "tapered" seals were "squishable", and I don't think they really are Kaw seals... nor were those sensors actual new style KAW OEM ones..
maybe they are, but unless there is a "K" and the p/n molded in the plastic I'd say no...I see both in your second photo, but the 433mh on the tag... well it ain't right.

when searching the net, or ebay...

somebody post a picture of the new style, with the real seal.... please..

And they even offer an installment plan!
That Amazon listing has been that way for a while

Thanks for your input Rich

Thanks Bud
I can't disagree with your photo, a I did find that one, and a few others when I was looking..

Back to JDSCO's original question now, the 2 different "valve stems" he wanted to use in place of a TPS unit, will work, using the gaskets Murph has...
the "hat shaped/stepped" flat style.
