This is the new BMW S 1000 R, a new naked bike derived from the S 1000 RR superbike. Fairings have been removed, and the engine has been reworked for better low- and mid-range torque, losing about 2,000 rpm of revs in the process.
The 999cc four-cylinder engine does 158 hp at 11,000 rpm and 112 Nm of torque at 9,250 rpm in the S1000R, compared to the S1000RR’s 193 hp at 13,000 rpm and 112 Nm at 9,750 rpm. The engine produces 9.5 Nm more torque than the S1000RR’s below 7,500 rpm. 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.
