TPMS recommendations

I strongly suggest changing to bolt-through metal valve stems or at least using compression tubes with rubber stems if the bike is capable of highway speeds.

90° rubber valve stems failed on my front tire at 80mph.not instantly flat, but scary, as the lower the pressure becomes, the harder it is to turn the bike. I believe it was caused by the back and fore movement when either checking or adding air into the tire. Rubber fatigue I guess. I immediately purchased a TPMS and tee valve stems and used them ever since. Probably the most sensible addition to my bike I've ever made.

This. The L-shape allows the stem to flex especially with added weight on the end. I noticed that on a 'Wing there was an additional support for the end of the L-shaped stem. Centrifugal forces an unsupported end of the stem to the rim at speed. When rotation slows down the stem returns to its normal position.

Short vertical stems won't have nearly as much flex with wheel rotation. Metal stems have none.
 
I received my new 90 degree stems today from Kurvey Girl and was wondering what orientation is best to install these in since I’ll be installing TPMS sensors onto them.

If I can I like to point them to the right so the stem is more accessible with the bike on the side stand.

Ditto. I'm generally not going to put the bike on the center stand to air up. It also allows for most any kind of air chuck to be used without extraordinary contortions of the hose.
 
I was just making sure that with the extra force of the sensors that it wouldn't be a problem pointing them outward without unbalancing things.
 
I like my Fobo2. It's within a pound of my Longacre gauge. Nice to glance at the phone screen while riding for a peace of mind.

My " Sykik Rider SRTP-300 " TPMS brand has worked for me . I don't have 90° stems though on the ST .

It's easy to make compression tubes to prevent the rubber valve stem from bending. The 5 - 7 gram sensor weighs 200-280 grams at 60 mph. The valve stem is bending over every ride at speed. Just find some plastic tubing larger ID than the base of the valve and smaller ID than the sensor and cut it to length from wheel to bottom of sensor when mounted. The cap off a Sharpie marker is just about right.
 
One bike has had the Fobo2's in use for 2 or 3 seasons now. It's a nice refined product and software design. As it should be for the price. The other bike has the $30 Chinese equivalent. It works,,, not well,,, and being spoiled for the Fobo's make's it seem like a $150 worth of frustration comes included. But they do work. I bought hogshead metal t-stems for both bikes. Once you have tpms it's unlikely you will do without it,,, imho,,, cheers, CAt'
 
At some point the FOBO 2s started including short metal straight valve stems. Not quite as convenient for every style of air chuck but still viable if someone doesn't want to bother with the "90º" stems.

I use Hawkshead TPMS on all four of my ST1100s.
They have given me great service and work well.
Their caps are some of the smallest in the industry and take button batteries that are easy to change.

Uncle Phil link gives 404 code "page not found" help me out.
 
Now that I visit the above it looks like they might not sell the ones that we have any longer. (Moto Track Cruiser 2)

SYKIK SRTP300 units have given me great service on multiple bikes. It mounts to the bike and does not use a phone. About $50 on Amazon. Several times my SYKIK alerted me to slow leaks when on a long ride when the tire would have gotten over heated from low pressure.

Based on your recommendation and that of a few other contributors to this thread,
I ordered and have now received the SYKIK brand TPMS system,
model SRTP – 300.

It's going to rain here all week, so I think I'll put the two sensors on my front tires on my cage for a few days to learn how the system works. Then I'll switch them over to the motorcycle.

I notice that the instructions say you have to ride for 5-10 minutes before you will get a reading on the display up on your handlebar/instrument cluster.

So, to prevent a situation where I begin a trip on a bike that only has 5 to 10 pounds of air in a tire without me noticing it until I get out on the public street I'll start thumping my tires with a hammer in my garage or my own driveway before I leave.
That should tell me approximately what my tire pressure is, give or take 10 pounds in either direction.

If I rode 10 miles away from home with one of my tires as low as 25 pounds, and then my TPMS system warned me about that, and I turned around and came back home, that wouldn't be a big deal.

I want to buy some T- valve or double headed valve stems to be installed in my tires the next time I do a tire change
(or potentially take one off for a patch to be installed inside.)

I currently have short straight metal valve stems in my ST 1300 wheels.

So, what's a good metal T - valve that I can buy and have on hand for the next tire change?

In this thread we've had one recommendation for something sold by WingStuff --a T valve that has one valve sticking straight up towards the wheel hub and the other coming out at 90° angle on one side. It's made to fit either the .453 inch or the .625" (11.3 mm ) holes in wheels. They cost $20 each before tax and shipping, so that's a pretty big price to pay just for a set of air valves.

Are there any other options that people know of for a dual headed, all-metal motorcycle wheel Schrader air valve?
 
Apparently the product being sold by
Wingstuff is also sold by several other online retailers, and it's from the company Hawkshead.
All of the websites that show a picture of it show an identical product.

But prices vary -- some are only $12 each.
