Hi Jerry,
Thank you for your question about buying a single angled valve stem to install on your 2020 Harley Tri-Glide trike, so that you can install an external TPMS sensor.
The simple answer is,
yes we can sell you a single valve stem. You will need to call us at 623-444-5022 to order a single valve stem.
But we want to share that
we do not recommend installing an external TPMS sensor to any valve stem, especially an angled valve stem.
- First the TPMS sensor will open the schrader valve, and the air pressure is being held by a gasket inside the sensor.
- Next the valve stem will be supporting the weight and force load of the added sensor applied. While the sensor seems light at around 9g, but at 60mph a normal motorcycle tire is spinning at around 850rpm.
- At 60mph, the force applied by the sensor on the valve stem is the equivalent of 3.25lbs.
- Up the speed to 100mph, and the sensor will apply a force of 8.8lbs.
- And while we know you are not planning on going 140mph, but at 140mph, the sensor force applied jumps to 17.5lbs.
Also, you should consider that no OEM motorcycle manufacturer, to our knowledge, installs TPMS sensors on the external end of the valve stems.
Again, thank you for your question, and we hope you understand the logic behind
our recommendation not to install an external TPMS sensor on any valve stems.
- It is your choice if you wish to install a TMPS sensor on the end of a valve stem. But understand this is not a recommended usage and that we strongly recommend against it when using one of our Angled Valve Stems.
