Mechanically the two bikes are relatively to be identical, its expected that the road going H2 may be offered in a different state of tune to the H2R but that is unconfirmed as of yet. For now perhaps we stick to the visual differences, or more appropriately, the lack there of.
As you can see from the transition there are two distinct visual differences evident right off the bat. First, the H2R offers a Double Bubble windscreen conducive to constant tucking on track, providing a much better flow up and over the riders back. The second noticeable difference is the exhaust pipe. As much as we would all love shorty megaphones there are regulations for emissions and decibels that need to be met.
The Aero effects are not likely to make the road going H2, we know for certain the upper wings will not be present, its yet to be known if the lower winglets will disappear as well.
Slightly harder to notice in the gif is the protruding rear fender and signal stalks. Also of note the gif makes it seem like the H2 and the H2R will have differing wheel bases, if only slightly. I'm not sure if this is just a consequence of the video where the picture came from or one that will show up at EICMA as well.
The last significant visual difference are the tires, we expect a street bike to have treads, it does. The H2R was displayed with Bridgestone Racing Battlax v01's. Based on the tread shown here the road going H2 will come equipped with Bridgestone Battlax RS10's
Luckily both the H2 and H2R will be offered in that spectacularly sexy Black Chrome Mirror finish.
As for the less noticeable differences, well you'll just have to wait until EICMA on Tuesday November 4th
