CV4 Quick Temp Strips 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 clean the area with contact cleaner, pull the backing off the temp strip and place it on your motor, radiator or shock for an accurate heat reading. The temp strip will change color (with green being the actual running temperature) as the item it’s placed on increases in temperature. As it cools down, the colors fade back to black. CV4 Quick Temp Strips have a measurable heat range from 149 to 248 degrees and will continue to give you accurate readings every time you ride until the strip is removed.
