The BMW R1200S is a sports motorcycle that was manufactured by BMW Motorrad between 2006 and 2007.
Compared to the BMW R1100S which it succeeded, the R1200S was 13 kg (29 lb) lighter, and (with a compression ratio raised from 11.3:1 to 12.5:1)[1][2] [3] it was 25% more powerful with 122 horsepower (91 kW).[4] Much of the weight saving was due to a new trellis-type frame which replaced the massive alloy frame of the R1100S. Although previous BMW flat twins had car-type dry single-plate clutches, the R1200S has a wet (oil-bath) multiplate clutch. But overall the R1100S was perhaps the more successful design. MCN said of the R1200S: "As an oddball track motorcycle it works, but as an accomplished all-rounder it falls short of the standards set by the R1100S that preceded it."[4]
In 2008 the R1200S was superseded by the double overhead camshaft HP2 Sport. At 178kg (dry) and 128 hp, it is even lighter and more powerful than the R1200S upon which it is based; (and compared to the R1100S, the HP2 is 30 kg lighter and 30 hp more powerful).[5]
Oilhead engine
The HP2's dohc engine was the most powerful "oilhead" design before BMW adopted liquid cooling for some of its flat twins in 2014. As of 2014 BMW still fit a 110 hp oilhead to production bikes such as the BMW R nineT roadster and the R1200R.[6] BMW are introducing a budget version of the R-nineT, to be called a "Scrambler". In 2015, the company declared that if the 1200 cc oilhead is not tuned beyond an output of 108 bhp, it can still pass emissions regulations.[7]
