yamaha yz 250 2stroke

Hi, I would convert my Yamaha 250 2 stroke 2007 mx version in supermoto. I find a used kit included: complete wheels,tires,discs,driven sprocket,caliper, master cylinder, spacers all for 850€ (about 1100$), but that was mounted on a Yamaha yz450 2007... Can I mount it on my bike without...
