The risk of having the inside diameter of your new oil seals pushed out during installation is one of the occupational hazards of working with forks. A simple mechanic's trick to avoid this is to attach a plastic bag or sack with a rubber band over the fork's downtube and pray the bag doesn't tear. The Motion Pro bullet greatly simplifies and speeds up the installation of seals. The tapered head makes it easy to attach the seal to the fork tube, while the spigot portion protects the inner diameter of the seal until you are seated on the down tube. When you work with multiple motorcycle brands with different fork sizes, the Motion Pro Bullet Set with eight bullets is an invaluable tool that saves you time by always having the right tool at hand. I highly recommend this tool.
