Hi everyone! We have a local dealer with 2 2017s, brand new, one is a 950 and other 950SW. What is the difference between the two? The 950 has aluminum wheels, SW has spokes. It's my understanding that the spoked wheels are heavier. Any advantage to having those wheels? I need a bike for adventuring gravel and light offroad. I also want something more comfortable for the lady friend. Also, are there full aftermarket luggage systems that you all would recommend for the MS 950?
