I had a Kawasaki I sold. It is now eighteen years old. It had 50,000 miles on it when I sold it. The new guy probably put at least another 10,000 miles on it. It still has the original factory hoses.
If I were to replace mine I'd go with factory hoses.
When factory hoses go bad they generally start weeping and splitting at the ends. And you can still extend their life by trimming them and getting a new place fore the clamp to bite.
