Using your AS3 Performance crash bars is easy. First, gather all the brackets and bolts that come with the product. Refer to the fitting instructions provided. Make sure your 2010 - 2013 BMW R 1200 GS Adventure is parked on a flat and stable surface. Follow the steps in the instructions to attach the crash bars to your motorcycle. As for maintenance, regularly check the bolts to ensure they are tight. You can clean the crash bars with a mild soap and water solution and a soft cloth. Avoid using abrasive cleaners as they might damage the textured matt black finish. If you notice any damage or issues, contact our support team as the crash bars come with a 12 - month warranty.
