"Just WOW! I've had a motorcycle license since I was 18, but I've never bought a bike. My dream was to buy myself a Harley by the age of 40, but it didn't quite work out. But shortly before my 41st I did. The Dr. Jekill & Mr. Hyde system simply rounds it off, it is pure riding pleasure when you are out and about in Mr. Hyde mode. That's how a Harley has to breathe. Just yesterday, I rode to a gas station, and when I came out again, my bike was being inspected by another Harley rider. I just said, can I help? His answer: just wanted to see what you're riding, it sounds mega, I got to have it. I can just say thank you! Legal with perfect sound."
