2021 WR250F with FMF 4.1 RCT revs with spark arrestor removed.

[Moto.Mishaps]

Got a 2020 wr250f I converted to supermoto, absolutely love it

[wesselvanwyk]

This Yamaha 250 WR is my dream😌 bike but i have a Yamaha 230 though😁

[Tyler-mivu]

got that pipe on my 17 wr450 and its perfect

[dustin]

Sounds like my 19 wr250f with a yz250f pipe

[YZFX]

Wow that sounds great low but what does it sound like when you wind it out? The stock muffler is like indy car crazy sounding on the yz450fx... everyone in the city knows if I light it up lol!

[theboogieman]

Where did u get the tail light I like that's it slim I have a klx140 I want to put a light kit on . Thanks

[ViewsMoto]

did you have to do anything else to it? i put the stock yz250f muffler on my 21wr250f so it would be louder, when i rev the bike no matter how warm it was it would stall or when down shifting into first it would also stall. That being said my connecting rod bearing did fail so could have been that

[Daniel-jppi]

Yo bro in your opinion, which one of those factory exhaust sounds the most aggressive?

[dominickungaro]

Will that exhaust work on a 2024, i am getting a 24' wr 250f and i cant find that exhaust for it

[FamilyMXTV]

Does is backfire or pop on deceleration for you with no spark arrestor? Just got one and don't know of it's normal or running lean

[stanimirgg]

can we please get some more of the sound i have the same 2022 bika an want the exhoust

[TwoThreadsAhead]

Is that rear light built in to the fender or is it just fixed to it ?

[markbaxter]

Hi, are there are proformance gains.

How does it compare to stock?

[Warrior-lsof]

What ahahaha I have the same sticker from rockstar on my wr250f 2004 I bet you just cut the letters out and stick the star
