BMW Motorrad has taken the wraps off the new M 1000 RR, a homologation special motorcycle that is based on the BMW S 1000 RR superbike. The new BMW M 1000 RR is the first motorcycle to roll out of the company's hallowed M-division, a dedicated facility that for the longest time has been making high performance variants of BMW's cars. The M 1000 RR is a homologation special, designed to meet FIM WSBK specifications and is road-legal as well. BMW Motorrad M 1000 RR is based on the sleek and angry-faced S 1000 RR, and hence shares most of the body panels.
The most obvious difference between the two motorcycles are the new carbon fibre winglets. BMW calls them M-winglets and these have been tested and developed using BMW Group's wind tunnel and on a race track. The winglets provide a maximum aerodynamic downforce of 16.3kg at 186mph or 299kph. One advantage of the downforce generated by the winglets is that it helps reduce the tendency to wheelie under hard acceleration, that in turn minimises the intervention of traction control. The winglets also help pin the front wheel down into the tarmac during hard braking and improve stability in corners.
The BMW M 1000 RR's 999cc engine uses new 2-ring forged pistons and each piston is lighter by 12g. The titanium connecting rods are 2mm longer and lighter, each weighing a mere 85g. BMW has also employed slimmer and 6 per cent lighter rocker arms, revised the intake port geometry, used titanium valves on the exhaust side and raised the compression ratio to 13.5:1. All of these changes result in a 5hp increase in power over the S 1000 RR and a redline that's pushed to 15,100rpm from 14,600rpm on the S 1000's engine. The specs stand at 212hp at 14,500rpm and 113Nm at 11,000rpm.
The BMW M 1000 RR's chassis is based on the S 1000 RR's, with the frame made of aluminium. The steering geometry has been optimised, with a flatter steering head angle at 66.4 degrees and reduced fork offset, by 3mm to 26.5mm. Besides this, the wheelbase has also been increased from 1441mm to 1457mm, achieved by employing a longer swingarm. The pivot point of the swingarm can be adjusted in keeping with the need to alter the geometry to suit a particular race track.
The brakes have been developed in association with Nissin and the calipers are finished in an M-divison specific blue paint. These calipers are lighter and bite on to thicker discs than those on the S 1000 RR. With the changes made to the chassis and the lighter weight, BMW claims improved performance, drivability and agility around a racetrack. Whether BMW Motorrad launches the M 1000 RR in Nepal remains to be seen. For more information about auto news in Nepal, stay tune with us.
