I'm certainly no expert but I think you'll be OK without a steering damper. Ducati was comfortable enough with the front end stability to release the 848 without a steering damper. You will be increasing the front end stability with added trail if you install the offset triple. I switched to a 30mm offset triple on my 1098 and the bike definitely holds a line much better in the corners now. I do have a steering damper but it's set at it's softest setting and I don't think I've ever needed it. I'm a street rider though so maybe a few of the track guys will post their experience as they push the suspension much harder than I do I'm sure. You could also email Dan Kyle as I've always found Dan willing to share his opinions and I've always found his advice to be spot on.
