Wife has a 2012 RT with elka shocks , been great. Went for a ride last weekend and we lost her said it was shaking real bad. Kinda surprised we lost her I had a 155 scooter and my daughter had my F3S . She said it was fine on the way back, thought it was the road that got her. So the next week she had me take it on the same road to see what it did. It was fine for me but I did get it to shimmy a bit when braking. Then I looked at the air in the rear shocks it was up 3/4. So I lowered it all the way and it was fine no more shimmy. We had it aired up from a long trip and her bike was packed full. Do you think it was that simple or could a alignment prevent this again. She is about 108 lbs me 195. The last ride bikes were m/t other than riders. Jim
