KEMIMOTO Motorcycle TPMS 2-Pack Tire Pressure & Temperature Sensors — Wireless 5.2, ±2 PSI Accuracy

The KEMIMOTO Motorcycle TPMS 2-Pack is a wireless tire pressure and temperature monitoring system that delivers real-time alerts, ±2 PSI accuracy, and up to two years of battery life for motorcycles, ATVs, and dirt bikes.

Riders who want fast, reliable tire condition feedback without complicated installs will appreciate this compact 2-pack. The sensors screw onto standard American-style valve stems and use Wireless 5.2 technology and a Freescale chip for stable data transmission to smartphones, headsets, and smartwatches. Designed for road and off-road use, these sensors report pressure and temperature changes while conserving battery life.

How quickly do the sensors start sending accurate readings?

The sensors begin updating when the vehicle is moving above approximately 20 km/h (≈12.4 mph) for about 20 seconds, then transmit continuous measurements. Accuracy is tested to within ±2 PSI and ±2°C, so you get actionable information when it matters most.

• Activates after ~20 seconds above 20 km/h (≈12.4 mph)
• Precision verified to ±2 PSI and ±2°C
• Designed to detect rapid pressure loss and heat buildup

Can I install these sensors myself and what valve stems are supported?

Yes — installation is simple and tool-free. The sensors use a screw-on design compatible with standard American-style valve stems (Type 19) commonly found on motorcycles, ATVs, and dirt bikes. They are not suitable for valve stems that protrude at a 90° angle from the rim, since that orientation can cause interference with surrounding parts.

• No wiring or special tools required — screw on and go
• Compatible with Type 19 American-style valve stems
• Not recommended for 90° protruding valve stems that risk contact

What devices can receive alerts and how many vehicles can I monitor?

These sensors use Wireless 5.2 connectivity to send alerts to smartphones, helmet headsets, and smartwatches simultaneously. Using the KEMIMOTO app you can add and oversee up to 50 vehicles, making it easy for owners of multiple bikes or group ride leaders to check tire status from a single dashboard.

• Real-time alerts to phone, helmet headset, and smartwatch
• KEMIMOTO app supports monitoring up to 50 vehicles
• Stable, ultra-low-power data transmission via Freescale chip

How long do the sensors run before batteries need replacing?

Each sensor uses factory-installed genuine cells with an expected run time of about two years under normal use. Batteries are UL1642 certified and factory-tested for safety and longevity, so you can plan maintenance without unexpected downtime during longer tours.

• Approximately 2 years of continuous use per sensor
• UL1642 certified batteries for safety and reliability
• Low power consumption thanks to Wireless 5.2 design

Who is this for? The KEMIMOTO Motorcycle TPMS 2-Pack is aimed at riders who want a straightforward, dependable way to monitor tire pressure and temperature without a complex install. It fits solo motorcyclists, dual-sport and dirt-bike riders, ATV users, small fleet owners, and group ride coordinators who need quick alerts to prevent common tire-related failures. If you value clear, on-ride feedback and long battery life from compact sensors that pair with modern devices, this TPMS offers a practical solution.
