Works as advertised! I've used them in the front and rear tires on my 2012 Yamaha Super Tenere for the last two sets of tires / 1.5 years / over 10,000 miles with no problems. I was skeptical but didn't want to buy the necessary equipment either. to balance motorcycle tires in the driveway, so I decided to try those first. After 10,000 km I am still happy and satisfied. I still don't get it, but it works!
