I have what appears to be cheap(ish) silicone hoses on a Kawasaki KX450 I acquired. They don't look bad, but they will be replaced by SamcoSport. It's one of those components I don't like having to worry about possible failure by a no name Chinese manufacturer. I've considered reaching out to Samco to see how many kits would be required before they considered making a kit for the ST. Until then, I will use OEM before an unproven (to me) brand.
