This is the new BMW S 1000 R, a new naked bike derived from the S 1000 RR superbike. Fairiings have been removed, and the engine has been reworked for better low and mid range torque, losing about 2,000rpm of revs in the process.

The 999cc four cylinder engine now does 158 horsepower at 11,000rpm and 112Nm of torque at 9,250rpm, compared to the S1000RR's 193hp at 13,000rpm and 112Nm at 9,750rpm. The engine produces 9.5Nm more torque than the S1000RR's below 7,500rpm. Cylinder heads, cam profiles and engine management software have been tweaked to produce the changes. The new tuning should be better for street usage.

The bike isn't really as 'naked' as most naked bikes - there's still various panels flanking the power plants, so it's more like a lady wearing a skimpy bikini than one who is completely naked.
