Ok color me confused, the H2-R is for closed course competition only, right. So then why would they build the thing minus a belly pan? Ok cooling, fine, but the majority of track days and clubs REQUIRE a belly pan....

Yeah i wonder why they decided not to have one. Not only would it look good, but it would aid in stability at higher speeds.

Having a belly pan would also increase the velocity of air around the components, increasing heat transfer(cooling) to the air right?

@NAOS I think you are on the right track. More so about drawing the heat away and cooling it down. Down the road I can see an aftermarket fairing company making a carbon belly ban for the H2.

I think they did not add one, because it would disrupt air flow exiting the engine?

The way it looks , air flow was a major component in designing these 2 monsters.

I saw a couple of pics with what looked like tabs with a wellnut or something right at the inner bottom part of the fairing...where it meets the radiator there.Can't see em in every pic...but they looked like attachment points for a lower fairing possibly?Would be nice to be able to save those very cool header pipes from road grime and such.They didn't appear to be part of the radiator/fairing attachment point.May have been actually welded to the bottom of the rad.????

Maybe after actually getting it...the idea of a belly pan may not be as important...this thing was totally purpose built...not having that pan kinda adds to the overall styling of this bird.I think anyway.Probably aftermarket will come up with something....lots of heat down there though....

I'm thinking similar as well, as mentioned in OP, you need a belly on track...

Not required to have a belly-pan as such, just a catch tray.

Obviously...they're not worried about grenading the motor

Just a personal opinion but I like to see the stainless headers snaking their way down and around. What I don't like is when manufacturers cover everything in plastic. This is why Kaw did not use a pre-muffler like ALL the others, they want you to see their handiwork!

I think it has to do with cooling. You can see how hot the exhaust gets (red hot). I am thinking that a belly pan could close in heat too much for the bike.

yea but watching them glow piping hot in WOT Dyno runs is not indicative of real world...

Regardless, unless they plan to offer one as accessory, most tracks are likely to say no bueno...

I agree, just a catch pan, just in case oil or coolant escapes motor.
Definitely need for track use, some tracks won't you allow you to
run without one.

Don't know how many SV 650's I have seen at a beginners race that have a foil turkey roaster pan strapped to the bottom of the bike... Looked crazy but satisfied the letter of the rules.....

Located this on Rickey's instagram: H2R custom paint and belly pan. Very nice looking. The belly pan sets it off.

I still think the H2 bodywork was a styling exercise and nothing more. If they were concerned about speed they would have given it something more like 'Busa or ZX14 lines. This was deliberate to showcase the engine. They could have easily included an insulated belly pan if they wanted to, but chose not to do it.

The bike will melt internally with a belly pan, or they would have given it one, next question, lol.

I would be willing to bet adding one would make the warranty invalid.

Not sure way one would say a belly pan on an H2 or H2R would melt. Moto GP bikes and bikes the run full throttle at Isle of TT have them and no melting. Also, more than likely some have titanium pipes. So not really sure if the melting comments are just sarcasm. I think its all about the style they were going for as to not put one on, to keep the weight down and as edinlr stated... showcase the engine.

I like the belly pan and located the possible original source. This motorcycle is a custom motorcycle of a trickster racing of a Japanese lacing team.
