Check your classic Japanese motorcycle owners' handbook. You'll be surprised to see that in many cases it is recommended to replace brake hoses frequently... every 3 years is quite common.
We see many terribly dangerous hoses that have been sent to us to replicate. Often the hose looks fine until you bend it - then the degradation of the rubber becomes all too apparent.
It's simply not worth the risk when you can buy top quality replacements from us at very affordable prices.
Here are some pictures of original Japanese brake hoses sent to us to replace. Would you risk your life riding with these?
