I weighed the stock wheels with all original parts and here is what I found.
Front weighed 25 lbs, rear 31.8 lbs.
I decided to try the new Michelin Power Cup 2 in oem sizes (120/70 front and 200/55 rear) - I weighed these new tires and the front weighed the same as the oem Pirelli Diablo Supercorsa SP (V2), however the rear was 1.8 lbs lighter! - that is quite a difference!
I weighed the complete wheels back to back on the same scale and the new complete wheels with the heavier/thicker than stock Brembo T-Drive 330 mm rotors and I knocked off a total of 4.4 lbs: front was 24.2 lbs and rear was 28.2 lbs - apples to apples the wheels save 2.8 lbs but those Brembo rotors are slightly heavier so with the same tires all all stock parts makes that difference shrink to 2.6 lbs.
The bike looks much better as well - would have been cool if Honda had just put forged Marchesini rims from the beginning....
I will make a separate thread about the Michelin Power Cup 2 changes to the geometry that may be needed but Michelin specifically states the following in their design brief : "Quick set up with no specific adaptions needed" so I will leave the geometry alone and try them; then make adjustments.
Pirelli Diablo Supercorsa SP (V2) 120/70-17
604 mm diameter (oem front tire)
Pirelli Diablo Supercorsa SP (V2) 200/55-17
656 mm diameter (oem rear tire)
Michelin Power Cup 2 120/70-17
600 mm diameter
Michelin Power Cup 2 200/55-17
665 mm diameter
When I switch tires I measure them and if I like the way the bike is already turning then I adjust the geometry of the chassis to get the bike to work the same way with the new rubber - in this case the shorter (-2 mm) front and taller +(4.5 mm) rear would require one shorten the length of the rear shock by 2 mm (linkage has about a 2:1 ratio) and raise the front by 2 mm but that isn't as easy as raising the front 4 mm so that is where I will go after a session of two of warmup - changing ride height at front or rear is not exactly the same but for 999 riders out of 1000 it is so check this space for feedback.
