Using your AS3 Performance crash bars is easy. First, take out all the parts from the package and check that you have all the brackets and bolts. Refer to the fitting instructions and follow the steps carefully to mount the crash bars on your 2008 - 2015 Kawasaki KLR 650. Make sure all bolts are tightened properly. When riding, these crash bars will protect your engine and fairings. As for maintenance, occasionally clean the bars with a mild soap and water solution to keep the textured matt black finish looking good. Check the bolts regularly to ensure they haven't loosened. If you have any issues within 12 months, you can use the warranty. Keep in mind that these crash bars are designed specifically for your motorcycle model, so don't try to fit them on other bikes.
