Aprilia New Reveal

It really doesn't trouble the RSV4R, though. The little Aprilia carves into the first left-hander, then flicks right as I wind back the throttle and send the bike accelerating off the second apex with a deep V4 growl. The bike is so stable and sharp that it feels like it could steer itself, and that's despite the fact that this is the cheaper, less extravagantly-fettered version of Aprilia's new superbike.

But it's no surprise that the R-model is this good, considering how much it has in common with the exotic RSV4 Factory with which Aprilia's V4 adventure began less than a year ago. The vital stuff is retained, notably the gorgeous bodywork and the 999cc, 16-valve V4 motor. The only engine-related differences are aluminium cases (instead of magnesium) and the lack of variable-length intake tracts that help prolong the Factory's peak power.

This bike also has conventional plastic bodywork instead of carbon-fiber and the frame isn't adjustable at the steering head, engine mounts and swingarm pivot. Instead of Öhlins components the R uses a Showa fork and Sachs shock, and the wheels are cast rather than forged. In total the R is 11 pounds heavier, at a claimed 407 lbs. dry.

This Portuguese launch wasn't actually the R-model's debut. The event was originally scheduled for Mugello, Italy, six weeks earlier, but was cancelled halfway through the first day after five bikes blew up due to a batch of faulty connecting rods. Aprilia was severely embarrassed, but thankfully the problem happened after six months of trouble-free production that had proved the V4's basic reliability.

Estoril was booked for the relaunch, and the Lisbon area's fickle weather just about obliged. The RSV4R felt wonderfully light and responsive as I headed out onto the track for the first session. Its steering precision and neutral feel made it wonderfully confidence-inspiring through the decreasing-radius first bend, and I was thankful for the steering damper every time the bike wheelied as I swung left and accelerated down the following hill. Much work went into fine-tuning the notably compact and well-balanced chassis, and it's quite evident when riding it. The 1000 handles like a trimmed-down 600, a benefit of careful chassis design which includes extending the fuel tank under the seat for improved weight distribution.

Perhaps the R's stationary intake trumpets meant I was shifting earlier, but if the R-bike was any slower than its Factory sibling, the difference was unnoticeable. It still charged toward its 14,000-rpm limit with haste, and repeatedly put 165 mph on the digital dash. And there's certainly no difference in braking abilities, since the R retains the Factory's Brembo Monobloc calipers and 320mm rotors.

Suspension action was sublime, too, even if the R's fork and shock aren't as refined as the Factory's. Spring rates are unchanged and both ends are fully adjustable, although the range is slightly narrower. Even when the track dried after lunch, the Aprilia handled superbly on showroom settings, and better still after I'd firmed it up with a little extra damping front and rear.

It's certainly an addictively fast and sweet-handling machine, with the same sleek looks, compact size, pure speed and razor-sharp handling that have made the Factory so popular with everyone who has ridden it. My only quibble is that Aprilia hasn't followed Ducati and BMW's lead in offering traction control, which would have been reassuring on the damp surface. But this is the base model, after all.

Aprilia's publicity materials claim the R's personality is significantly different, but I disagree. It handles so well and is so blisteringly fast that the performance on road or racetrack would be almost identical for all but the very fastest riders. The Factory's upgraded components are nice, but with a price $5000 less, I'd pick the base model every time.

Inevitably the R's aggressive character and compact size mean it won't be the most practical or versatile sportbike, any more than the Factory is. Some people have suggested that Aprilia should have attempted to broaden its appeal by softening its power delivery or attempting to make it a bit more comfortable. Thank goodness they resisted any temptation to do that. The Factory is a stunning race-replica that fully justifies its high price; and the RSV4R is a majestic mass-produced superbike that provides similar style, performance and thrills for a lot less money. You really can't go wrong with that.
