Up for sale is a brand new Yoshimura carbon fiber slipon for the '08+ Ninja250r's. I bought it to replace my 2Bros, but decided not to cause I just love the sound of the 2Bros. I opened the box with the intention of installing it, so I can't say that it's sealed, but I assure any potential buyer that it's brand spanking new. My asking price is $400 obo and I prefer selling it locally. Contact me at [email protected]. Shoot me an email for pics. Thanks for looking. I'm located in Downtown Los Angeles btw.
