the braided steel line is not designed the same as the plastic oem line. there is an extra fitting at the master cylinder end to increase the size. this makes for a very weak connection that is not very durable.lasted three rides.
I opted for this cable over the stock hard-platic line after mine melted through due to the previous owner routing the line over the cylinder head. I highly recommend this cable as there is no cable expansion and since it's braided you don't have to worry about your bike being clutchless while in the middle of the woods!!! Installation was a breeze and the only thing you need is mineral oil which Motosport sells or you can out-source it.
Does this line keep it from melting against an exhaust?
The original carbon line melted against my exhaust in about one minute...even though I tried to route it as far away from the cylinder head and exhaust as possible for its length. Does this line alleviate the problem and is it heat resistant ?
The urethane protective sheath is not heat resistant. The purpose of having a steel braided hydrologic clutch line is to minimize the expansion of the line during clutch actuation.
As to how you're routing the clutch cable seems odd, I don't understand how it would cause the line to come in contact with the exhaust. I know on my bike the clutch cable comes in from the right side of the frame and mounts to the left side of the motor. On most mx bikes the exhaust pipe comes off the right side of the motor. unless your talking about a RM85 or something.
But to answer your question, this line will not alleviate the problem of melting when it comes in contact with the exhaust pipe. The urethane protective sheath is only there to protect the stainless steel line.
It comes with a plastic line and all necessary fittings. Remove cable, perch and lever. Then install, lever all the way to the clutch arm. Braided line is great insurance against damaged, or melted plastic line.
