Using these hose clips is easy. Just place them around the hoses of your Honda NT 650 GT Hawk RC31 where needed. Make sure they're tightened properly to ensure a good seal. When installing, be gentle to avoid damaging the hoses. As for maintenance, since they're made of marine - grade stainless steel, they can resist corrosion well. But it's still a good idea to check them regularly, especially if you ride in harsh conditions. Look for any signs of wear or looseness. If you notice anything wrong, you can use the 12 - month warranty to get them replaced. And remember, these clips are designed for AS3 Performance and OEM hoses, so don't use them on incompatible hoses.
