  • Product information



    Stainless steel is a collective term for rustproof steel. It is much more resistant to corrosion than non-alloyed steels. Stainless steel does not deteriorate, and is hygienic, UV-resistant, non-corroding, fracture-proof, non-toxic and environmentally friendly. It does not weather and can be recycled in its entirety, even after many years. Technically, the term "stainless steel" refers to corrosion-resistant steel alloys with a wide variety of compositions but always containing a high percentage of chromium (usually a minimum of 10.5%)


    Stainless steel should be cleaned regularly like all other materials, especially after exposure to salty air (near the coast), and also at regular intervals.
    Water can easily collect in corners, edges and screw connections, resulting in corrosion. So careful cleaning is important, and if necessary screws should be undone in order to clean the parts thoroughly.
    Do not leave rusty steel parts against stainless steel to avoid the rust "contamination".

    Product information



    This product is made of high-quality aluminium and will look great on your motorbike. To ensure that it gives you years of pleasure, please observe the following instructions: To keep this product in top condition, it should be treated after long trips in winter, or in rain or salty air (near the coast), and also at periodic intervals.

    Water and salt encourage corrosion. After cleaning (e.g. with Procycle Special Gel Cleaner, Order no. 10004909), we recommend regularly polishing aluminium parts with standard aluminium polish (e.g. Alu-Magic, Order no. 10004031).
