I used contact cleaner before installing and heated up the Metal with a blow dryer. They just don't stick well around the welds on the frame and it pops up, you get a little dirt in their and they're done! Good idea just a waste of $20
After a few rides my boots were beginning to rub the paint off the frame. These stickers are plenty long enough to cover from the subframe to tank but I cut mine shorter since I like the looks of the white frame. They are very sticky and pliable enough to contour to the frame near the welds. They have an abrasive texture for gripping the bike. No complaints and they are holding up well after several months.
