My 18 roadster has a pretty good shake to the bars between 40 and 50 right now. I thought i may not have done a good job balancing the tire as i did it myself but i had the shop put a back on and rebalance the front and it was slightly worse after they "rebalanced" it. My fjr had the same problem and I replaced the tire and it went away. My solution is to just keep one hand on the bars at all times.
