Works - 2026 YZ250F
It works but barely fits the stock exhaust of a 2026 YZ250F.

Better & less expensive than FMF pipe plug
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.

Banshee plugs
They work decent for the banshee, the rubber is a little stiff, I have a hard time getting them to stay inside the exhaust.

Simple but a must-have for washing our race bikes
As a moto mom with bikes getting washed almost every weekend after the track, this little exhaust wash plug has been super handy. It’s one of those small things you don’t think about until you realize how important it is. The plug is made from thick rubber and fits snugly in the exhaust, which keeps water, mud, and debris out of the pipe while washing the bike. That’s especially important on two-strokes because you definitely don’t want water getting into the exhaust or engine components. I like the tapered design, because it fits a range of exhaust sizes (around 0.6"–1.5"), so it works on different bikes in the garage without needing multiple plugs. The bright “remove before ride” style streamer is also helpful—it's a good reminder before starting the bike so you don’t forget it’s still in there. Installation is about as easy as it gets: just push it into the muffler before washing the bike. It stays in place well and pulls out easily when you’re done.

Too hard
These are very hard rubber and don’t easily press into silencers. They fall out.

Overall great product
Works great. I wish I got the smaller size of the two for my YZ450F and TRX250EX though. The larger size fits, but barely. The material is rubber and flexible and the added remove streamers are a quick reminder and draw attention. Value for the money is spot on!

Buen tapón, mala tela
El tapón es bueno, el problema es la tela roja, es demasiado delgada, no es de buena calidad, se lo cambié por otro que tengo.
