Overheating is the main reason your bike loses power and performance. Today’s high performance race bikes are at the cutting edge of development and continue to push the limits of existing technology. Pro Circuit Thermostrips come in a package of three so you can monitor the running temperature on your motor, shock or radiators to make sure you’re not losing performance due to overheating. Simply pull the backing off the Thermostrips and place it on your motor, radiator or shock for an accurate heat reading. The Thermostrips will change color as the item it’s placed on increases in temperature with a measurable heat range from 149 to 248 degrees. As it cools down, the color fades back to black. These Thermostrips will continue to give you accurate readings every time you ride until the strip is removed.
