The VN750 was made during Kawasaki's innovation period. Shortly after the VN750 was made, Kawasaki hit a 20 year slump. They kept models unchanged, and failed to push themselves.
The Vulcan 750 was unchanged for 20 years. Some say it's a testament to good design, but in reality it was laziness of Kawasaki. The same goes for the Ninja 250, Concours 1100, etc.
When the Vulcan 750 was designed/made, it was a great bike (1985/86). As the years drew on, the fact they failed to build off the initial innovation is really disappointing to me. The Vulcan 800, and 900, are un-noteworthy, and not a true forward advancement from the 750. We don't see hydraulic valves in the new bikes, etc...
