WR250R改290cc、USヨシムラのスリップオンサイレンサーです。
250ccでは抜けが良過ぎますが、290ccではちょうど良いです。

  • I mean buy not but:)))))))

  • Would u but your first bike yahama wr250x? Enduro or Sumo?

  • Your throttle skills are phenominal!

  • @fbs9494 hell yes

  • @whitesoxx35 you fucking dumbass

  • ok the link for the bigbore kit says its getting 50 HP to the rear tire obviously thats bullshit because a stock 250race bike witch the wr250 is not because its geared for the street has on average 34HP a 450 race bike is stock at 45-50 HP depending on model and brand. If the the chart was true this bike would be pulling 4th gear wheelies no prob i have ridden one and could barly get the front end off the ground in second so what is the actual DYNO measurment im guessin 35 to the rear tire

  • @whitesoxx35 you are just dumb yeh the bags are gay but if it wasnt for the japanese this bike and a lot of other bikes wouldnt be here dont call them dirty untill you have come to japan

  • Now why the he'll would you ruin that perfectly good bike and put those damn bags on it. If it were meant for those the would have came stock you dirty jap
