Although I love Ducati (I'm on my 4th and did more than a dozen track days on my 749), and agree there is a lot of useful trickle down technology from Moto GP, not necessarily everything translates to the street. What's best for lap times at Estoril is not always best for how we ride. I think World Superbike with production based engines and frames have a more direct relationship to the sport bikes we ride. By the 2nd year in SBK, Aprilia's RSV4 was dominant. The 90° layout might be best for 250 hp Moto GP bikes, but I haven't yet been convinced it's an advantage over the narrower Aprilia layout for sport bikes. And as mentioned, the Aprilia trounced the new Ducati V4 in a head to head test last year (granted, the Aprilia had 10 years of refinement to draw on). Undoubtedly they're both incredible bikes, and let's be honest, 99.9% of us are only capable of riding them at 75% of their capabilities on a good day. The very idea that we could buy a 5 year old RSV4 for under $10k with all that technology is mind-blowing. How lucky we are!
