      Wondering which is best for a CR125 application.Do I mount the pipe cradle section with a rubber vibrasorber on it or do I mount it solid? I`m guessing a solid mount so that it moves exactly with the engine movement(seeing as how the other end of the mount is attached to the engine)

      And what about the muffler mount as well,solid or use a vibrasorber?

      Nigel,

      Intuition is not your friend here…it may look like a solid mount will keep everything together, but it won’t. Vibration will have all kinds of things flexing or trying to flex, but you need to absorb the vibration as best you can in order not to crack the pipe. The rubber isolator wins.
