Maybe the powerplants are like everyone else's because the mfgrs have figured out that these configurations are relatively inexpensive to poroduce and are reliable and produce good power.
RUNE?? say what? The RC51 powerpant is like everyone else's? Everyone else's what? Not the last time I looked. Remember that these powerplants are used in racing so they are constrained by series rules. Ask Ducati about having a "different" powerplant in AMA.
I'd like to see Honda come out with an all-new Gold Wing/Valkyrie, this time upping the ante to a 90-degree V8, DOHC, 32 valves, variable valve timing and lift, direct injection. Use the technology to get power and torque comparable to the GL1800 in a lighter, smaller-displacement package.
Also, why are you just looking at Honda? Are you a stockholder concerned with their rate of innovation? Or are you looking to buy a bike? If you're looking to buy a bike, why do you care about the entire Honda line? My guess is that you're one of those Honda die-hards who buys into the Honda hype, i.e., Hondas are super reliable and the best quality machines out there in any category they compete in.... Well in my opinion that's just hype. I could start a whole new thread with that one...you've seen it before. "Are Ducatis reliable?" Etc. etc.
If you really want cutting edge look to manufacturers who dare to be different like KTM. Or go exotic and get a Cagiva. Really, it comes down to a bike-by-bike selection process and you have to be open to every manufacturer, depending on the need you're trying to fill.
Ah mediocre tastes. Nothing wrong with that though. But what is wrong is that the Rune had only US product run. Its next to impossible to import it to EU. I called the Finnish importer and as I wasn´t the first caller they lay the law as it was directly off the bat. Sum up is that only way is to work in the US and take it back as moving goods. Hope you guys don´t have anything against illegal immigrants.
