I'd be down for some forged aluminum wheels. Forged magnesium would have added cost to the tune of $2K+. Either way, IIRC, the wheels on the standard 937 already went on a diet relative to the 821 wheels. Why an SP? This is not the same SP as on their V4 bikes -- the level of trim and performance is different as is the price delta. The Monster SP falls into the same level as all the other 937 motor SP bikes, and is priced accordingly. And I'll argue that $18K to $20K for a Monster SP would be a tough sell.I disagree. Monster SP should come with lightweight wheels. I did not say full carbon wheels though. Forged at least. Providing factory forged wheels should be the bare minimum. The stock cast wheels are too heavy. So why call it an SP? Why not simply make it the S if you are not going to upgrade the wheels? Also, carbon wheels are not made only for SSA bikes. BST makes carbon wheels for dual sided swingarm bikes also. So does Dymag, so does Thyssen Krupp, so does Rotobox, etc.
I am well aware that carbon wheels are available for non-SSSA bikes. But the wheel YOU used as an example (SF V4SP) is the (original) variation of BST's RapidTEK and that is only available for SSSA bikes at the moment, and it's not likely they would retool the rear wheel for a limited number of Monster SPs. AFAIK, the other carbon wheel manufacturers are not contracted with Ducati, and Thyssen Krupp AG no longer makes wheels as I understand, though I doubt it's because of the failures they had when they were providing wheels for the S1000RR.
