I would think any motorcycle brand that the technology changes on very quickly would be hard to keep up with unless the mechanics went to school regularly. Most of the high tech bikes don't ever get overhauled just finally replaced. The electronics and the add ons are probably the most problematic. Most younger guys understand the computer parts of their bikes at least enough to read a tool that plugs in and tells them whats up. I'm an old guy and of course know some other old guys and as a whole we are out of touch with new technology. I started to lose it when they replaced my kickstarter with an electric one. I recognize the smoothness, power, better brakes with the new stuff but need a dealer or someone besides me to work on it. I've built many Harleys and can do anything on the V8 bikes so I'm not just mechanically challenged but I am obsolete. Here is a picture of my car we took yesterday on a trip. This has the kind of technology that is no problem for me.
