Vibrations in the steering wheel

Hello, with my V 50 the steering wheel vibrates like a small vibrator. Have already had new tires raised, but that didn’t help anything. Always have the impression that I’m directly connected to the road and notice every little stone. It’s the case that I steer only down with 2 fingers on longer rides, because I get on my nerves when it’s constantly vibrating. It doesn’t flutter, just vibrate, but visually you don’t do anything.. Does anyone know advice???? My kinder because. Many greetings wool
