Coitak Muffler Exhaust Wash Plug, 0.6"-1.5" Wash Plug for Motorcycle Bike 2 Stroke Rubber Exhaust Silencer (2 Pack) (0.6"-1.5")

No issues with fitment on stock TX300 silencer. Measure your diameter and you'll have no issues. The rubber is only slightly stiffer than the FMF version. For the price and the quantity, it's a good buy.

As expected

Bought this because the cheap “Remove Before Flight” flag on the otherwise higher quality FMF pipe plug didn’t even hold up to the wind it was exposed too in the back of a pickup truck for my 3 hour drive back from my off road motorcycling spot. As most all other reviewers noted, these plugs do not seem to be made of rubber as advertised (maybe urethane?), so they’re not supple like the name brand FMF plugs. Nonetheless, they fit my 2024 Kawasaki KLX140R F (and 1978 Honda CR250R Elsinore) stock pipes perfectly, and the “Remove Before Flight” flag is nylon attached to a metal ring so I expect it will hold up much better than FMF cheap vinyl flag.

KSR80とKX85に使用。運搬や洗車、車庫保管時が安心。届くのに時間がかかるのでAliExpressの方が安価でいいかもしれません。
