Well, I finally got them in and put them on. It's close, but after riding around the yard for a bit and hitting some curves at full lock and such, I think things will be fine as I haven't had any rubbing yet. Granted, the bike has only 20 hours on it, so the stock spings may sag a bit over time, but I plan on swapping out to stronger springs before it's all said and done with. I was looking for maximum ground clearance for rolling over logs and such in deep woods riding, so I went with the biggest 589's I could find. I'll be heading out to the spillway this afternoon to really try them out.
