You are hopeless. YOu guys were the ones who tried having this argument and now you are saying they are apples and oranges. BWAAAAHAHAHAHAHAHAHAHAHAHAHAHAHAHA!
Liquid cooling has only been around since the late 80's and early 90's for the jap bike market. The gsxr will only do that at unbelievable high rpms and only do it for a short time. It's torque is much much lower so we are back to bragging about hp with no substance.
Please read up a little bit on the internal combustion motor(this is what these motors are, just in case) and then when you actually know what you are speaking about come back and correct me. Until then you are just wasting bandwidth. I know a lot of people who are riding 100+ ci motors everyday and just in case you didn't know Harley is also offering one. It seems you are lost when it comes to this discussion.
Actually, liquid cooling on bikes has a history that goes back at least 50 years, possibly longer, although it didn't become common until the Japanese started using it, as you said.
And I guarantee you I know way more about Harley-type bikes than you do about Japanese bikes.
At full throttle most of those big cubic-inch v-twins would overheat in less than a minute. Of course, the GSXR1000 couldn't run at its HP peak forever either, without overheating, but it could run near it all day.
