well youve probably seen the swingarm extensions for the blaster and banshee in dirtwheels, but the reason why it is possible is because the whole bearing carrier BOLTS on to the swingarm, so what they do is give you a piece of metal to bolt the carrier on , then you bolt the peice onto the swingarm...hondas carriers are housed INSIDE the swingarm so to do this would be almost impossible, plus it makes it weaker
