Not trying to be a smart ass, right off the top. Many new Ducati owners think their bike runs rough below 4000rpm. Itís a twin, and it isnít counter balanced or rubber mounted, thatís part of it. For an engine tuned for a high rpm capability, below 4000 rpm is not where it wants to be, and itís gently telling you so. BUT, itís maintenance record is probably unknown ? Engines run smoother when in good tune. Little things can go out of adjustment over time , like synchronization of throttle bodies, valve adjustment, timing, chain adjustment. These can effect how smoothly the engine runs. Chains can wear, causing vibration. Spark plugs can get dirty. Address all these things, put the bike back in good condition, maintenance wise. Then see how much it vibrates. Many owners drop a tooth on the front sprocket so the engine revs into the smoother range quicker. You might try that. Or change to a bigger rear sprocket if the chain needs replacement. The basic thing is donít ride around under 4000rpm when you can help it. Good luck.
