Greetings and salutations! This is my first post here on the board, so I'll toss out a brief intro before getting into my questions. I live in the Kansas City, MO, USA area, and recently was told about Royal Enfield bikes after looking some at vintage BSA and Triumph models. I was specifically looking for a 500cc bike, and the ability to get a modern bike that size with some real style is great. I'm wanting something to be a more fuel efficient alternative to my daily driver currently, a 1964 Ford Falcon station wagon. OK, here's the questions: How performancewise does the AVlL compare to the old iron bore engine in real life riding? By the specs sheet it would appear that it has a bit more power on the top end, but both specs show a 75mph top speed, with a 5mpg bonus to the AVL on fuel use. Secondly, I do travel a fair amout on 70mph speed limit highways- is running at that speed once the bike is properly broken in a fair cruising range or 'flogging' it pretty hard? If i was buying new, I'd definitely go with the AVL, however, if I found a used model I just want to know if an iron bore would still be almost as good for my needs if the price was right.
