Kawasaki heavy industries are one of the highest tech companies in the world. Motorcycles are at best a hobby for them. To be honest, I sort of admire that they even bother, and building a bike like the H2R is really a gift to us riders. Further, I don't think they are in competition with Suzuki anymore as the H2s sort of ended that war.
I don't think they will even update the 14 to Euro 5, as it's not where their head is at. It's interesting I read an article where Kawasaki HI has this super CNC machine that can cut 20' diameter ship props from a single billet of metal. Apparently, they are the only ones who can do it, at least at the time of the article. So it kind of makes sense they would go with forced induction as they are the number 1 export on impellers.
Then again, they might need the 14 engine updated for the concourse (do they still sell those?). Anyway, it's a shame if those 2 bikes are gone and as far as sales I'm guessing they outsell the H2 lineup.
