They did not add an intercooler because, Guess what? They did not need one.
When the H2R is traveling fast, the forced air induction into the charger is also
keeping it cool.
The extra weight was also a factor.
I don't know about you and how you ride, but I've been running centri blowers since the early 1990's, and I don't feel comfortable running boost without a intercooler.
I hope that Kawi have engineered something for intake temps.
