I don't see any mention of that ... but it wouldn't surprise me.
The "basic bike" costs the same because it is all the same stuff. Different camshafts don't cost any different to manufacture.
The carbon fiber bits on the track one are expensive. But not $25,000 expensive.
On the other hand, the track one lacks: Muffler, catalyst, headlights / signals / wiring, probably a lot of the wiring harness, rear fender / license bracket / light / wiring.
Stuff gets expensive when it is only built in tiny quantities. If you think the H2 is going to be built in tiny quantities (likely in the hundreds), that's nothing compared to the H2R (likely in the dozens).
