To nearly everyone, the new YZF-R1 felt comparatively weak in the midrange, just like the old 20-valve motor did. And it shows on the dyno, the 16-valve mill making roughly 10 fewer ponies than the GSX-R at 7500 rpm. Peak power was also down.

With a longer reach (0.5 in.) to clip-ons mounted 1.1 inches lower than the GSX-R1000's, the R1 didn't generate rave reviews in terms of comfort. Bothersome midrange vibes and plenty of heat emanating from the engine's flanks didn't help.

We're not sure why our 1098 cranked out fewer ponies than the S-model we tested last month, but with the same engine it should have been closer. Still, nearly 140 horses at the rear wheel puts it on par with the legendary 999R, which is a flat-out brilliant powerplant.

With the longest reach (by a whopping 0.5 in.) to its bars and the next-to-lowest clip-ons (the ZX-6R's are 0.5 in. lower), the Ducati loses the comfort contest by a decent margin. Still, the desmo V-twin's lumpy, high-amplitude vibes weren't bothersome in the least.

Stick And Go
Pirelli Diablo Supercorsa Tires

It was one of those perfect, crystalline instances of group cognition. Our crack panel of track testers was performing one last brain dump when I suddenly remembered the Pirelli Diablo Supercorsa race tires that Josh and Garrett from TigerShark Racing (www.tiger had mounted on all five bikes earlier in the day.

"Before I forget, what did we think about those new Pirellis?" I asked. We all stared at each other wide-eyed, and someone voiced what each of us was individually thinking: "Tires? I didn't think about them once."

Though it sounds dismissive, that's perhaps the highest compliment you can pay a race tire. The Pirellis performed flawlessly, lap after lap, and required absolutely no attention from the riders, leaving us free to focus on riding.

Like the Dragon Supercorsa Pros that preceded them, the new Diablo Supercorsas were developed specifically for the World Supersport Championship. Both front and rear feature a flatter shoulder to increase the contact patch at intermediate lean angles for higher entrance speeds and improved grip during trail-braking. A more elastic carcass with optimized ply density allows the tire to react and respond to mid-corner line corrections more easily and elongates the contact patch at high lean angles for higher corner speeds. Lastly, new compounds formulated to maximize ultimate grip and a revised tread pattern with an increased slick area on the edges increase grip for faster corner exits.

What this all added up to for us was utterly transparent performance all day long. The Diablo Supercorsas ($279.95 front, $343.95 to $367.95 rear) were essentially ready to rock and roll right off the tire warmers, maintaining exceptional grip even in demanding, off-camber Turns 2 and 3 and providing long life even on the darkie-dispensing R1 and GSX-R1000. They're great skins for going fast.
