Dang, was hoping for all 4 modes as well. Not a deal breaker just yet… but that is a shame. At least 3 would be nice: Quiet mode for freeway—100% drone-less ride. Normal/Sport, and a Baja-balls to the wall mode.
Would be cool if there’s just an axle back version as well. I’m more bothered by the dinky, stock tailpipes than the sound.
Either way I’m excited to see and hear it!
