Thank you for prompt response. I went to tooling about 400 kilometers by installing it immediately. I think it is not enough to melt the pants although it gets quite hot. I think that combination with thermo tape is good as well.
It was a motorcycle that I used for commuting, and since it was melted by the heat of the muffler many times on a rainy day, I tried to take measures. Thing that it melted at the moment of being touched by thing attached, but this muffler guard itself is still high temperature, once removed and wrapped in a muffler strip shaped glass wool, and attached this guard on it, It became much better. Also, since I think that the attached fixed band will be able to do anything, I replaced it with SUS 304's one.
Although it was not difficult to install, it did not know whether it would fit or not match the motorcycle in front, so it actually did not fit, but I installed it forcefully but it is usable without problems. It looks better if there are various band sizes attached from the appearance.
It is recommended to use with thermo shield tape. It becomes heat to the extent that it can be touched by hand when used in combination. If it is a new muffler color, it can be assimilated and used without discomfort. Design is also good.
