CB 250 ou 4OO Twin ou Hawk selon les pays... Voire connue sous d'autres appellations?
Made for Movie is my guess. I think so, it's too much costumized. Anyway the others six or seven motorbikes (bad boys) are Yamaha. This bike has the same style of front axle fixing as the other bikes in the movie so i presume it is another Yamaha. Probably a TT250.
i think its more like the other bikes in the chase Yamaha YZ 125/250. "Mad Mission part 2"
Obviously these 6 or 7 motorbikes (bad boys) crash during the chase vs white motorbike unknown (customized). Here we can read are Yamaha either Honda or Yamaha 2-stroke motocross bikes.
