Aside from aesthetics, the engine designs are fairly different as well. While all are powered by large-ish V-twins, you’ve got a couple of overhead cam models in the Victory and Kawasaki, and the de rigueur pushrod motor from Harley. On the chassis front, Harley is once again in the traditional camp with a steel frame, but so is the Vulcan, while the Vision boldly employs a cast aluminum skeleton and unconventional layout, with the gas tanks up around the steering head. For all these differences, the running gear is pretty close, with similarly-sized rubber on all three machines; only the Vulcan is significantly different, with a 16 inch front wheel, to the other two’s 18-inchers. Weights are fairly close, despite appearances, as are the wheelbases, with the Roadie coming up a couple of inches shorter than the other two, thanks to offset triple trees. Just a few years ago belt-driven 6-speed touring bikes were fairly rare, but all three of these are equipped exactly that way.
