I have owned a 2011 and 2014 Spyder Canam and really enjoyed them but it was time for change so I bought a 2016.5 Sl slingshot. I have had back surgery and have a bad hip and tail bone but after getting in and out a few times it is easier than the Canam. My hip would hurt like hell when I swung my leg over the seat and my back and tail bone would complain the whole time while riding.
While not perfect it is much less painfull to sit in a reclining postion for me. I can ride for hours without complaint and I can find more postions to ease the pain when it starts.
Is the Slinghot a motorcycle, no, it is much more like a europen sports car; low, nible and fast. It has a ton of accessories that can be added including turbos and super chargers so the fun never ends in that regard. As long as I am out in the open air I am happy, loved my past motorcycles, my Canams and now my slingshot.
I have added some performance upgrades and look forward to shocks and a supercharger in the near future. The handling in corners is much better than my Canam with the elka shocks, it is scary fast!
I loved my Spyders and recommend them to any one that asks but the attention this machine gets makes for some great conversations at gas stations and parking lots.
