Using these hose clips is easy. First, make sure your hose is clean and in good condition. Then, place the clip around the hose where you need it. Tighten the clip securely, but don't over - tighten as it might damage the hose. When it comes to maintenance, since they're made of stainless steel, they're quite resistant to corrosion. However, it's still a good idea to check them regularly, especially if your motorcycle is often exposed to harsh conditions. Look for any signs of wear or looseness. If you notice any issues, you can use the 12 - month warranty to get them replaced. And remember, these clips are designed for specific models (2011 - 2017 Aprilia RS4 125), so don't try to use them on other vehicles without checking compatibility first.
