Depending on how much you tip the scale, the rear shock might be a little limp. Check the preload adjustment before you roll out the door by having them measure your static sag. That's the amount of drop with you sitting on the bike. Too much and there isn't enough travel left to soak up the big hits. My Bobber was a spine buster on big bumps because of the limited travel on the shock. Putting an Ohlins TR729 under it cured the problem. The Speedy has a preload collar the Bobber doesn't so you can fix the sag, no adjustment for compression or rebound damping but you can access full travel of the shock so that's better than the Bobber that way. You'll also notice a lot less heft in the handling with the proper suspension settings. Enjoy your new (to you) ride.
