2011 Aprilia RSV4 Factory APRC SE | PRICE: $22,499

Dyno
Midrange is the Aprilia’s mission. Torque is underwhelming below 6000 rpm and falls off shortly above 10,000 rpm, but between those marks the output is stout and easy to access thanks to the 999.6cc V4’s responsive, quick-revving character.

Ergos
Like everything on the mass-centralized RSV4, the riding position is compact. The short seat-to-bar distance is fine for keeping the front end down at the track, but coupled with high footrests literally cramps your style on the street.


2011 BMW S1000RR | Price: $16,630 (As Tested)

Dyno
The S1000RR’s dyno graph will make even the most confident Hayabusa or ZX-14 owner cower in fear. Peak numbers are impressive, but what’s more remarkable is the thickness of both curves. Power increases steadily and rapidly from idle to redline.

Ergos
It’s not quite as plush as one of BMW’s mile-munching sport-tourers, but the S1000RR is the most comfortable bike here. Generous measurements, a stellar saddle and wide, flat clip-ons create a reasonably relaxed riding position.
