Very straightforward installation. It is complete with everything you need to put it on quickly. Material is thin, as it has to be to clear between the belt in the tire. The Plastics material is thin but strong. Its design is to prevent small stones from being flung off the tire and thrown onto the belt. I purchased this after having to replace a belt with only 7000 miles due to a stone which had been tossed upon the belt and of course landed on the edge, not the middle, the worst possible place. Even though I was able to replace the belt myself, these belts are pricey. Not to mention the inconvenience. That tire is so close to the belt, that is amazing that they last as long as they do. I change motorcycle tires for a living, and there are it's always tell tale signs of wear on the belts and cogs from foreign material that is kicked up and then ground through the belt. I see on the Harleys all the time. So the bottom line is, this little piece of plastic could save you hundreds of dollars and aggravation. For what it cost oh, well worth the peace of mind. And by the way, avoid freshly chip sealed roads like the plague on any belt-driven machine. Chip seal is the belt killer!
