VOL. 52 ISSUE 24 JUNE 16, 2015 P103 you hit third, making me glad I had the Sachs steering damper well wound up. But hold the gear and at 10,000 rpm there's another dose of top end power that will send you rocketing forward as the engine heads for the revlimiter in a way that's seri- ously satisfying, and definitely dramatic. There's a degree of rideability that's literally intoxicat- ing, especially when combined with the APRC rider aid pack- age. You especially can't help appreciating the smoothness of the perfectly dialed-in pow- ershifter, no auto-blipper for clutchless downshifts, which is a pitty; this would allow you to just tap in one gear after another with the throttle wide open in a flawless manner worthy of a fac- tory Superbike racer. BONES OF A CHAMPION In spite of the subtly altered chassis geometry, I found the new Aprilia's handling on a par with the RSV4's, which is to say: excellent. Well, maybe it should be, since this is the same chas- sis that the reigning World Su- perbike champion has. The one- piece handlebar gives enough leverage that you can soon forget about the longer wheel- base in terms of compromising agility, but the big surprise was how rock-solid stable the Aprilia super-streetfighter was under fierce acceleration. No handle- bar waving in the wind, no speed shimmy even when you hit a bump, just totally planted. Aprilia was aware this could become a problem with a naked bike with such a high potential top speed, so it made extensive wind tunnel testing in designing the revised half-fairing, and especially made sure it's mounted to the frame, not the forks, in pursuit of stabili- ty. The Sachs suspension on the RR version I was riding seemed a little stiffly set up, but both the piggyback nitrogen rear shock with the variable-rate linkage off the RSV4, and the 43mm upside down fork are fully adjustable ⎯ compression damping in one leg, rebound in the other ⎯ so with more time I expect I could tion on four-cylinder machines, to protect the 1000cc twins. By the time this restriction was removed from the SBK rulebook for 2008, when they allowed 1200cc twins, it was too late for us to change. So to get more displacement in Tuono form for more torque and more riding plea- sure, we simply increased the bore from 78mm to the 81mm we always intended it should be, while maintain- ing the same stroke. There's no auto-blipper system on the Tuono or the RSV4, which seems strange considering Aprilia has always led the field in electronic assistance, and so many of your rivals have now adopted this. Why not? We are working on it. We have the technology, because it's on the Superbike racer. But we are be- hind in bringing this to the street, though it will follow later this year.
