Haven't rode it yet but I have it on my "Bucket List."
I've seen a lot of photos of friends riding "the Dragon" and have heard many stories. I've even talked to someone who wiped-out and lost his bike. Yes, he lived to tell about it and share some very good advice. Never allow anyone to push you pass your limits. Ride it like your life depends on it. Enjoy the moment.
The Dragon is a great ride. Just be smart about it! Ride within your limits and take it slow and steady. Try to avoid going on weekends! It gets very crowded and a lot of people are trying to go as fast as they can through it.
Another thing to watch out for are the semis (18 wheelers). When they come around a corner, they can't help but be in your lane too. So be ready to stop if needed.
Another good ride after the Dragon is the Cherohala Skyway but watch out for police (they come out in force some days).
Don't give up on the Dragon, it is fun if you ride smart.
