Make sure you ride one first, and I'd ride a Bonny the same day if possible. I'm pretty sure the Scrambler has a 270 firing interval. The Bonny has a 360. I remember my Speedmaster had a 270 firing interval and it had a bit of buzziness in the bars at much over around 70 mph. The Bonny SE has zero buzz.
That said, my Thunderbird has a 270 firing interval it has zero buzz in the bars too and I've had it up over 90 a couple of times so what the hell do I know.
