A twist and go throttle and no gears are nothing new, I have a bike in my garage which is exactly that.

There is also nothing new about HD bikes being 4 times the price of other bikes, no doubt the spares will be the same rip off.

What I would like to know is, how are Harley Davidson going to replicate the deep roaring sound of a 1600cc V twin on a silent electric unit.
Will the electric unit have a drop in cassette with different sounding roars to choose from.
