The controls (clutch, shifter, brakes, throttle) feel a bit clunky to me compared to most of the Japanese bikes I've ridden (lots of them). To me that is part of the Enfield's charm (I have owned a '66 Bonneville and ridden a late '40s Indian Cheif) You even had to adjust the ignition timing manually on that thing. But it was very enjoyable, and I got the hang of it pretty quickly.
But I still say a Japanese bike is better for a beginner. Not sure how I feel about the looks of the Vulcan S, but it has a solid engine. But it will be over $8000 OTD, and it's not a tiny bike. I would not want to drop an $8000 bike. There are so many used Japanese bikes you can pick up on Craigslist for $1500 that would make excellent beginner bikes. If you wanted new, the CB300F is an excellent standard style bike with a somewhat reasonable price.
I started out on dirt bikes at age 8, and was well past my dropping bikes stage before I got my first street bike at age 16, a used early '70s Suzuki GT380. I rode that about 3 years, and after having a job for about a year, bought a brand new Suzuki GS450L. I have yet to drop a street bike in over half a million miles of riding. I credit luck, and my dirt bike experience for that.
