Using these hose clips is easy. First, identify the hoses on your 2018 - 2019 KTM 250 or 300 EXC TPI motorcycle that need the clips. Then, simply place the clips around the hoses and secure them tightly. Make sure they are firmly attached to prevent any leaks. When it comes to maintenance, since they're made of 18/8 marine - grade stainless steel, they can withstand most conditions. But it's still a good idea to check them regularly, especially after long rides or in harsh environments. If you notice any signs of wear or looseness, replace the clips right away. Remember, these clips are designed for AS3 Performance and OEM hoses, so don't try to use them on other types of hoses. And as they come with a 12 - month warranty, if you have any issues, you can get in touch with the manufacturer.
