How Long do the Oil Cooler Lines Last?

[Jeff in W.C.]

I have a 1988 R100 RT and I'm wondering how long do the oil cooler lines last.

My cooler lines are 42 years old. They look ok.

They last until they start to leak...

When I had my '93 R100RT, I used to spray them with silicone spray and the rubber always remained pliable. I've had my 2004 R1150RT since new, (rubber oil cooler lines also), and have still done the silicone spray trick, and they remain pliable 19 years later, with 130k.

They're known for lasting a very long time.

So after 35 years, they are not leaking, look OK and are somewhat pliable. But, I've noticed more and more parts for the monoshock bikes are becoming unobtainable. I may replace them so they would last another 35 years. Another thought is with the shift away from ICE to electric motors, manufacturers may stop making and selling parts.
