This skid plate is constructed with the best aluminum for this application.
Working tens of tons of aluminum every year we can say that we know this material well, which comes in different types, each suitable for specific purposes. Some are very soft and could bend with bumps despite its thickness. Others cannot be bent as they would have cracks which over time would lead to breakage, others react to welding through “cooking” and become weak in the welded areas.
This type, however, is perfect for this application, which I also use for the tanks on rally bikes. Extremely hard, but which can be bent and welded without presenting the drawbacks described above, it is the same aluminum that is used in applications in the automotive field but with very different thicknesses.
Our skid plate boasts a base of 5 mm, the one stressed by impacts, while the walls are 3 mm. The skid plates of the rally motorcycles that we have made over the years have never gone beyond 3 mm which I think is sufficient, but for safe measures we went a little further.
