I have! Mines rubbed the swingarm and the engine casing. I did like Matt did and roatated the loop away from the case a bit, and just put a bit of tape under the cable on the swingarm. Its worn through too.. I guess while it shows signs of wear I don't consider it excessive. Bikes done 9000kms or more now (who knows.. trailtech shat itself).. It'll go a few more kms yet too.
