Yeah, baby! Sounds like a jet liner on the video. Oh, those poor poor folk who "love the sound" of loud bikes! It looks like one of the advantages of electric bikes is not having to deal with packaging an exhaust system.

Just get the Harley CD and run big amps Chuey . :D

That bike is heavy so the motor must really kick out the torque ! I wonder if they use engine braking / recharge ? That would really slow it down when needed.

The problem there is that a race bike gets very little of it's braking from the rear. I think you'd need 2-wheel drive for engine braking to be really effectively used, and that, of course, creates many other complications - especially on the street, where different diameters and the wheels following different paths as you turn create differential issues that are less problematic with the limited grip of a dirt bike.

Gee Wizzzz... I wonder how much of what we hear is tire noise, besides the wind?

Some form of charging via the front hub but driving from the rear ?

I hope my next bike will be electric. I just hope I can be shielded from the radiation.
