Using these hose clips is easy. First, find the right place on your KTM 125 or 200 EXC radiator hose where the clip needs to be installed. Then, simply place the clip around the hose and tighten it properly. Make sure it's secure but don't over - tighten as it might damage the hose. When it comes to maintenance, since they're made of marine - grade stainless steel, they can handle different weather conditions well. But it's still a good idea to check them regularly for any signs of wear or looseness. If you notice any issues, you can always rely on the 12 - month warranty that comes with these UK - made clips. Also, remember that these clips are designed to fit AS3 Performance and OEM hoses, so use them accordingly.
