2012 MV Agusta F4 RR claims to be most powerful sportbike in the world

The Italian bike manufacturer just peeled the wraps off of the 2012 F4 RR, and the new machine packs a full 198 hp between its frame rails. That's thanks to a host of new engine tweaks that start with a redesigned head with larger titanium intake and exhaust valves. Full power comes on at 13,400 rpm thanks to a shorter stroke and new lightweight forged pistons, and variable-length intake runners and a 4-2-1-4 exhaust makes sure the mill breathes easy.

A close-ratio gearbox backs up the powerhouse, and a rash of Ohlins hardware helps keep everything under control and on the ground. Multi-adjustable 43-millimeter forks and a stabilizer bar work together up front while a TTX 36 rear shock handles damping duties out back. Owners can custom-adjust nearly every aspect of the suspension, including the steering angle.

The 2012 MV Agusta F4 RR also rocks forged aluminum wheels to skimp on pounds, though dry weight still sits at a fairly hefty 423 pounds.
