Best TPMS for Motorcycles: How to Judge One There is no single answer to which motorcycle TPMS is best. The six criteria that actually separate systems, a scorecard to fill in, and who each design suits.

The question behind the question

"Which TPMS should I put on my motorcycle?" is usually asked as if there were one answer. There is not. A track-day rider, a long-distance tourer, a scooter commuter and a distributor building a private-label range all need different things from the same category of product, and the system that serves one of them well can be actively wrong for another.

What follows is not a ranking. It is the set of criteria that actually changes outcomes after the box is opened, written so that you can score any candidate — ours included — against your own use case. Our own sensor is described at the end, under the criteria where we think it fits and the ones where it does not.

Criterion 1 — How it mounts, and who can fit it

There are two mounting styles and they are not interchangeable.

A valve-stem replacement sensor screws onto the valve in place of the original cap-and-core assembly. Fitting takes minutes, needs no tyre removal, and can be done by a shop or by the rider. It is the style that makes a two-wheeler TPMS viable as an accessory rather than a workshop job.

An internal sensor sits inside the tyre, fixed to the rim, and the valve is replaced with a dedicated one. It is better protected and cannot be removed by a passer-by, but every tyre change becomes a TPMS job and the wheel has to be rebalanced.

The question to ask is not which is better in the abstract. It is: who will fit this, and what happens at the next tyre change? If the answer is "the rider, on a driveway", you want the valve-stem style.

Criterion 2 — The battery, and the service life behind it

This is the criterion most often skipped and most often regretted.

Ask three things. What cell is it? A standard, buyable cell is better than a proprietary pack. Can the user replace it? A sealed sensor is a sensor with a disposal date. Does the sensor have to be re-paired after a battery change? This is the one that hurts. A sensor that forgets its identity when the cell is swapped turns a two-minute job into a support call, on every wheel, for the life of the product.

Our BPU100 answers these with a CR1632 coin cell, replaceable by the user, and pairing that survives the swap. We consider that line more commercially important than any radio figure in the datasheet.

Criterion 3 — The app, and what happens when a reading is missing

With a Bluetooth system, the app is half the product. Two questions expose most of the risk.

Which platforms, and is that fixed or per project? An Android-only app is fine for some markets and a blocker in others where iOS dominates.

What does it show when a sensor drops out? Every radio link misses packets. An app that holds the last reading on screen and stops updating is worse than useless, because the rider cannot tell a healthy tyre from a dead sensor. Ask a supplier to describe the behaviour explicitly. If the answer is vague, that is information about the product.

Also worth deciding early: who controls the alarm thresholds. In an OEM or brand programme, the answer determines whose customer experience it is.

Criterion 4 — Sealing and the temperature range

A sensor lives on a valve stem in ambient air, in rain, in road spray, in sun, in frost, and near a brake disc that gets very hot. The specification should say what the sensor is rated for and how that was established.

Look for a stated operating temperature range, a storage range, and a humidity condition. Then ask what testing stands behind them. This is where suppliers become evasive, and it is worth pushing: a range without a test method is a slogan.

Our published figures are −20 °C to +80 °C operating, −40 °C to +85 °C storage, and 5–95% relative humidity, non-condensing. We run water-immersion and powered-ageing steps in-house. We do not publish vibration, thermal-cycling, EMC or drop-test data, and we will say that plainly rather than imply a test report that does not exist.

Criterion 5 — Wheel-position marking

Small detail, large effect. If both sensors look identical and are not marked, the fitter has a fifty per cent chance of getting front and rear the wrong way round, and the rider then sees a rear alarm on the front wheel. It is a support ticket that never needed to exist.

Ask whether the sensor is laser-marked by position — L.F, R.F, L.R, R.R — and whether the marking work is part of the standard build or a special order. On a four-wheel ATV or a three-wheeler this matters even more than on a bike.

Criterion 6 — Private label, and how deep customisation goes

If you are a distributor or a brand rather than a rider, the product you buy is not the sensor. It is the sensor plus marking, packaging, documentation, app branding and support.

Get the layers separated in writing: marking only; marking and packaging; the addition of your part numbers; the app carrying your identity; changes to the BLE service or data format so the sensor feeds your own software. Each layer is a different level of effort, and the difference between "we can put your logo on it" and "we can change the protocol" is the difference between a purchase and a programme. The private-label page sets out how we split those layers, and the ODM overview covers the engineering side.

A scorecard you can fill in

Criterion	What to record	Our BPU100
Mounting	Valve-stem or internal	Valve-stem replacement
Cell	Type and availability	CR1632, standard
User-replaceable battery	Yes / no	Yes
Re-pairing after swap	Required / not required	Not required
App platforms	Android / iOS	Android available; iOS per project
Missing-reading behaviour	Described / vague	Covered in the app spec
Operating range	Published figure	−20 °C to +80 °C
Storage range	Published figure	−40 °C to +85 °C
Humidity	Published condition	5–95%, non-condensing
Position marking	Standard / optional	Laser marked by position
Private label layers	List	Marking, packaging, app, protocol
Wheel counts supported	List	Two, three and four

Score your own requirements first, then score the candidates. The column that matters is the one where a candidate scores badly against a requirement you actually have.

Which design ours suits

We built a Bluetooth sensor for two-, three- and four-wheel vehicles, with a replaceable CR1632 and pairing that survives a battery change. It suits a rider or a dealer who wants a no-harness fitment and is happy to use a phone; a distributor who wants a private-label accessory rather than a display kit; and an OEM that wants the sensor to feed its own app.

It is a poor fit for a rider who wants a permanent dash readout with no phone in the loop, for a machine where the sensor and the display are far apart, and for anyone who needs published vibration or thermal-cycle qualification before they can buy. In those cases the honest recommendation is a different architecture.

Where we stand

We make the sensor in Shenzhen. Capacity is 30,000 sensor units a month, and more than 10,000 sets a month go into the Chinese two-wheeler aftermarket. Eight in-house test steps — pressure calibration on every unit, water immersion, RF range, protocol verification, powered ageing, battery current, appearance and dimensions, and a full wheel-position system test — run before anything ships. Certification is handled per market and per project, and we will set out the current position in writing.

If you want the scorecard above filled in against a specific vehicle and market, send us the vehicle, the wheel count and the market and we will answer in those terms. The full sensor specification is on the BPU100 product page.
