Harley-Davidson TPMS: fits the valve, not the badge Touring models on cast wheels take a valve-stem cap sensor directly. Spoked wheels with inner tubes are the exception, and on a heavy motorcycle the reading lag matters more, not less.
Ask about your model See the sensorWhat this means on a Harley-Davidson
On a cast wheel, the sensor is a cap on the valve: no receiver, no wiring, and a phone reads the pressure. On a spoked wheel with a tube, the sensor is measuring the tube - the reading moves slowly and a small leak takes longer to show. For a heavy touring bike that is a safety argument for using a wheel-mounted sensor instead, and worth saying plainly.
Two practical notes: the rear valve on some models is awkward to reach with a pump once the cap is fitted, and the rider should be shown how to read and remove it before the bike leaves.
The sensor, in numbers
| Item | Value |
|---|---|
| Radio | 2.4 GHz BLE 5.1 - no receiver, no wiring |
| Pressure range | 0–500 kPa gauge (0–600 kPa absolute) |
| Accuracy | ±2 kPa |
| Battery | CR1632, about 1.5 years at the default reporting interval |
| Sealing | IP67 |
| Body | diameter 21 mm × 16 mm, 20 g (sensor body, without the tee) |
| What it needs | a phone (iOS or Android) - the phone is the gauge |
Which valve you are dealing with
Fitment is a valve question first, a vehicle question second. Three cases cover almost every two-wheeler:
- Rubber snap-in valve on a tubeless wheel - the most common case. The sensor is a valve-stem cap: it screws onto the existing stem and nothing on the wheel changes.
- Metal clamp-in valve - common on larger or performance wheels. It also takes the cap sensor; check that the cap has clearance inside the rim.
- Tube-type wheel - a spoked wheel with an inner tube. A cap sensor reads the tube, not the air in the tyre directly, so readings react more slowly; the honest answer is that the wheel wants a different mounting, and it is worth asking before ordering.
What to check before ordering
- Rim clearance - with the sensor on the valve, does it clear the brake caliper and the fork at full travel?
- Valve condition - a cracked or bent stem leaks; replace it first, then fit.
- Wheel balance - 20 g on one side matters at sustained speed on a light motorcycle; on a scooter it usually does not.
- Pressure range - our range is 0–500 kPa gauge. Most two-wheeler tyres run well below that; the ceiling matters for air-shaft and industrial use, not for road tyres.
What the rider sees
Pressure and temperature per wheel on the phone, with the sensor's own battery state. The point is not a dashboard: it is seeing a slow leak before it becomes a roadside stop, and a temperature rise on a long climb before it becomes a tyre.
