Big Bike Parts® has updated the popular TireGard™ Motorcycle Tire Pressure Monitoring System with an all new easier to read universal display. With the broad market acceptance of TireGard™ the decision was simple to make our 2-Wheel Monitor easier to read with larger read out numbers and a simplified presentation. All the same information is still displayed on the 1 ¼ inch key fob display, but is now more easily interpreted, making this top seller even better. Lightweight sensors do not require wheel re-balancing and includes G-Force sensing to increase battery life. Batteries included, 2 minute installation.
