So I just picked up an extremely clean 05 raptor 660. I even owned quads and bikes back in the days, but know nothing about this thing. Bought it on a whim, and seems to be a great buy. Only have driven it around the block. Everything seems to be Damn near new. Tires still have nipples on them, even the paddles. This thing has never seen dirt and doesn't have a scratch on it really. Does have a really nice poliahed eyeball engineering swingarm? Which I can't seem to find much info on. Does anyone know anything about this swingarm and how to tell if it's longer than atock?
