It's you not the motorcycle
The BajaRon bar will help with stability of the motorcycle. If the cross winds are strong enough you are going to start to be a Sail! You will catch the wind and you will be blown in such a way you may feel you are being blown off the Motorcycle. We had 45 and 60 mph crosswinds in South Dakota, and Wyoming and my wife had a very hard time holding as she was driving. When we turned into the wind the RT was totally wide open and all it could do was 70 mph and drained the gas tank in 89 miles. There are some times when you just have to stop and wait for it to blow over. The impact is far less than what you would experience on a two wheeler!
Passenger seat is a B**** with strong crosswinds
Have riden many miles in the drivers seat and as a passenger on the RT with the wife driving when we're two up and switching off with the driver duties. With strong cross winds the driver has it made with good wind protection, and we've enjoyed Ron's swaybar upgrade on the 11 RT for 70,000 miles. Usually the strongest crosswinds seem to be coming across Kansas from SpyderFest in the Springtime, and I would much rather be the pilot than the rider in those conditions. Just part of riding. Bad crosswind days just make you appreciate the tailwind days when they come.. not much you can do about it other than try to "tuck in" behind the pilot.
