Riding a street-legalized H2R on the unrestricted stretches of German Autobahn is my ultimate street motorcycle fantasy.

Kawasaki claims 380 km/h top speed for this beast even though it has touched 400 on the speedo in Turkey.

There was one of these running on the streets in the US after being equipped with headlights, mirrors and some other stuff to make it street legal. I'm not able to find the thread now, but it had many details of the significant amount of differences in many places between a H2 and an H2R. As per the poster, the H2R was in a completely different league with full blown no-compromise exotic KHI (Kawasaki Heavy Industries) (aerospace-grade) stuff used everywhere (The guy had put in a lot of work understanding the differences before working on it).

The guy who had carried it out had posted some motovlogs too, but he deleted his channel, but some copies of the video are still there (not posting here as the riding in the video may be against the rules)

That was the 'tame' 200HP H2. The H2R we are talking about here is the full-blown beastly version representing what KHI is capable of.

To put it in a simple way (with my limited knowledge), forced induction engines run low compression ratios as the compressed air would already be under high pressure and running high compression ratio with it would result in very high temperature and high stress on the components. The lower temperature assisted by lower ratios also helps in running advanced ignition timing. 8:1 ratio in supercharged engines is quite common.

It says "ride within 4000 rpm/6000 rpm. Which means anything under is good, but do not exceed said RPM limits for those 30 minutes.

Nopes, he didn't. That's just the normal H2.

We're talking about the H2R here - the difference in performance between the two is just too much!

Yeah my bad. This was indeed the H2. The 'R' is a different beast altogether.

I hope this owner posts some videos with the beast in action. Would be drool-maal.

Within 4000rpm for the first 30 mins and then below 6000rpm for the next 30 mins. Correct?

My statement was pointed towards the passive resistance the rider would need to exercise while carrying out this task on such a bike.

Cheers!

That is right.

Actually, all these bikes are pre-run at the factory. If you look up on youtube as to how these are run in at the factory, you'll be damned to follow the instruction booklet.

Running in, is just a covert way for a manufacturer to let a new owner ease in into using the vehicle and get used to it. Its almost like a liability clause.

And lastly, if the guy does not have the patience for the first 30 minutes or an hour, he's probably going to be a death wish on the roads.

PS: Some of these apparently high strung bikes on paper - are actually very easy to ride at low speeds pottering around in higher gears.
