I agree it wont happen. I like my concours 14 engine, but its not a great engine for a touring bike. It really does nto start working well until its at 120mph. Its fun, but something with more low end would be nice.
With the butterflies removed , its pretty good. Even though its more powerful than my Ninja 1000, you'd swear its not. Thats as much to do with gearing, but the overall feel.
The bigger zx14 motor is really more of the same. The zx14 would be incredible if it were set up for long distance riding. For 99% of street use, its riding position is comical. It feels great when your over 100mph, but under that, forget it. Its power is awesome, but BMW does that 200hp figure with 1000cc's, and a hundred pounds less weight than even the zx14.
They wont go to the big 14 motor because I think the party about over with regards to the massive engines and emissions. The next generation will likely be a smaller, 140 hp version of Kawasaki's h2.
