So sorry for not responding, but I didn't see your post. You've probably already figured this one out, hopefully not the hard way. But...Yes. I left them on once for some off-road opportunity that I couldn't pass up. It wasn't planned and I was too lazy to remove them. Dinged the crap out of them! If you're on any trail with light terrain or broken tracks, you'll be relatively fine, but you'll run the risk of denting, destroying, or ripping them off if you encounter any obstacles, even light obstacles. They are for mostly on road use. I like them, though and it keeps me from having to help the wife in, but if I'm planning anything rough, off they come.Very nice! If I recall Beluga black was a pretty rare color for NAS. Question, I just bought my 1994 NAS 90 and it came with the factory side steps you have on but they were still in the box not installed. Not sure if you do much off roading with yours, but if you do have you noticed any material impact on ground clearance? I'm contemplating keeping mine off but it would be a bit easier to hop in the seat with them installed.
