Welcome, welcome! You're found a great cycle, and a great online community to help keep it running.
My wife and I recently started riding, and the Vulcan is my first cycle too. It's not a bad starter bike, not a perfect one either. It's VERY powerful and not exactly light. I laid it down (looow speed) three times in my first couple of months. I'm confident and comfortable now that I've learned to ride, learned the cycle, and gotten some experience in traffic.
My advice to you: Take the cycle safety course if you haven't yet. Start small and easy - find quiet streets within a mile or two of home to practice on. Stop, start, turn, over and over until you don't think about the clutch. Practice low-speed turning, quick stopping. DON'T head out on the open road or dance in traffic until you feel confident on the cycle.
Required Reading: the Hurt Report summary of causes of motorcycle crashes. By telling you what causes crashes and injuries, you can learn how to AVOID them. http://www.clarity.net/~adam/hurt-report.html
Finally, don't let your friends or other riders tell you you don't need:
- The safety class
- Lots of skills practice, not just road riding.
- A helmet and other protection. ATGATT, no excuses.
The Hurt Report found lots of things we can do to avoid accidents and not die when they happen. Sadly, most riders continue to ignore this excellent information. They ride without armor, wear clothing that makes them hard to see. They WILL try to convince you that their way is best, when they're contributing to cycling's terrible safety rep. I'm an ATGATT guy in a screaming yellow jacket, and have had to endure many stupid comments from no-gear black T-shirt riders. Then they tell me all about their crashes and road rash and stitches, like that's better somehow!
But enough about that. Start slow, take it easy, and you'll be roaming the open road in no time. I'm having a blast on mine! Happy trails!
