Is there a 90 degree valve stem option for the NT?

[basketcase]

Several years back I put these on my GL1800. It made checking and managing tire pressures much easier.

Is there such an option for the NT?

If the link doesn't work, browse to Amazon and search Showchrome 90 degree valve stem. Thanks!

Those should work nicely on the NT wheels.

If you've got (or want to have) a Tire Pressure Monitoring System, you probably need to have an external mounted sensor. These are what I'm using now. They let me mount the sensor on the top of the stem and then check and adjust pressure from the "T".

You do need to have access to the inside of the wheel to get the stem securely mounted.

Back in about '02, I was riding a Kawasaki Concours and had one of these (https://www.amazon.com/dp/B0BJF2JQVB/ref=syn_sd_onsite_desktop_0?ie=UTF8&pd_rd_plhdr=t&th=1) that I had bought from a BMW store in Denver. I had just pulled onto the Interstate and was up to about 75mph when I felt a little twitch. The next thing I knew I was in a tankslapper and thought I was probably going down. I pulled in the clutch and didn't touch the brakes and finally came to a stop. the centrifugal force of that little brass 90-degree extension had torn the rubber valve stem nearly completely off. Don't use a 90-degree stem with a stock rubber stem.

Honda first fitted a 90-degree stem to the CX500T (Turbo) and to counter any worries about centrifugal force applying undue force to the rubber seal, the wheel had a support tab that kept the stem at 90-deg. Those angle stems used a rubber seat identical to normal (straight) stems so having the upper portion at a 90-deg angle would apply some force against the rubber seal at the rim.

I've seen Gold Wings where owners have fitted absurdly long, chrome 90-degree stems which seems worrisome and they reminded me of long stems used on semi-truck rims!

Thanks to all for the feedback. I have the ones at the link in my op on my GL1800 and have not had problems. I'll wait and do then when the tires are next renewed.

I have something similar on all three of my bikes and have never had a problem. They are called "12 mm" but the real size as measured is a bit smaller.

I recently completed the MSF Advanced rider course and the instructors there had couple of these to inflate tires that work great with regular stems, if you're already a Ryobi one tool user it's a cheap option. The digital PSI gauge is very accurate from what I can see, matches up to another gauge I have that I know is accurate. I'm sure the other battery toolmakers have them too. I bought one right after the class.

RYOBI introduces the 18V ONE+ Cordless High Pressure Inflator with Digital Gauge (Tool Only). The Cordless Power Inflator is the perfect tool for tires and small inflatables ranging from 0 PSI to 150 PSI. It features an easy to read digital gauge that provides pin point accuracy. The cordless...

I have used stems similar to Dirtflyers with success. I think mine came from Soundrider.

You can get the shorty stems that are identical to the OEM Honda stems at any auto parts store, part# TR412. Change the stems with every new tire install. I just carried a bicycle style pencil gauge with me. Didnt want to deal with the bent stems. A standard Milton 90 degree air chuck works fine.

Keep it simple and ride on!

+1...
The latter is kinda mandatory anyway...

The chuck on EC style tire fillers on the gas stations are a bit easier to use on motorcycle wheels...



But since I like to measure cold tires in the morning, I got me this thing (electronic ones will fail soon; heat, humidity, vibrations, low batteries give wrong values...):



and now we're also equipped with those:

Use a metal angled stem. They won't flex and break, and they age better than the rubber ones.

"...they age better than the rubber ones..."

I've been using the short-angled stems for eons and have never had one fail. Periodically, I'll change the Shrader Valve but the stem stays in place. They use a flanged vinyl seal that seems thin but works nicely because it has a machined surface on each side - one on the rim and one on the valve.

I've bought the shorty, alum stems from three different on-line stores and they always look identical. My guess is that there is a giant factory in China churning these out by the millions then sending them to different retailers.

The 1990 Pacific Coast had 90 degree valves.
