YFZ swing are in alittle longer I think & heavier It might work but the way the YFZ bolts up more like a blaster the swingarm blot goes through the motor and as you know a banshees dont so even if you was to there your swingarm bolt would be getting rusty, & really dirt. If might work but I wouldnt wanna try it you might & might get it workin but it more trouble than its worth.
