I am very interested in the R3. Years ago I owned a Kawasaki Ninja 250 that served me well. I learned to ride on it but sold it for a little more power (Suzuki SV650) and one other major reason.............buzzieness. My hands would go numb after a while on the highway. I had to put foam grips on the bar ends and wear gel work out gloves to make it managable. How is the R3 at highway speeds, say 70 to 75mph? Do you feel the engine vibrations at all through the bars?
