The Bonnie is a biker's bike. It's got purity. It's also faster, better handling, and, most importantly to convince your wife, it will handle a passenger better.
I started on a VLX and have ridden numerous Hondas. They aren't bad bikes, but they are just another product alongside their cars, generators, marine engines, lawn mowers, and robots.
I'd guess your VLX will feel rather lackluster once you've tested a Triumph.
