Perhaps the next evolution for the Goldwing is to go hybrid.
I know we're still waiting for the definitive results for how reliable the DCT will be, but in the interest of keeping the Goldwing the King of Motorcycles perhaps hybrid is the way to go.
Remember that we're already using the starter as the reverse motor, so improving that would actually make navigating a parking lot easier. Of course, the main reason for hybrids is the ability to get away with a smaller Adkinson cycle engine, but I'm unsure if Honda will elect to go with that or to just make the Goldwing even more monstrously OP.
I also understand why Honda wouldn't want to bother with that, because fitting what is essentially a compact car's transmission between our legs is impressive enough. Squeezing yet another all-new transmission... Ooph. The same problem for any new engine they might consider, because I really have no idea how a flat-6 Adkinson would behave, especially at low gear/RPM.
