Question for experienced riders

I test rode a Stryker today and loved it. I do have a question, though. I haven't ridden since I was a teenager (I'm 50 now) and I've never ridden anything like a Stryker. While I didn't have much trouble handling the bike I did notice that the driveline seemed rough with vibration. Is that just typical of a belt driven motorcycle? Is this what's referred to as driveline lash? I apologize for my ignorance but I'm really curious if this is how the bike is supposed to feel. I appreciate any feedback.
