Still trying to get a copy of the pics. I've ridden harley's before and this is way way stronger than that. As an amusing note, the thing connects to the coil for a controller, which means the higher the revs the stronger the pulse coming from the seat. That being stated, at highway speeds apparently the vibration coming from the motorcycle almost matches the seat. So given the feedback I've been provided with, the best way to deploy this thing is at low speed. The most fun that a person can have at 5 Mph.
