The BMW HP2 Sport is a boxer-engined sports motorcycle produced by BMW Motorrad from 2008 to 2012. It is the successor to the BMW R1200S.
Design
The engine is a 1,170 cc flat-twin "oilhead" with air-cooled cylinders but oil-cooled heads. Derived from the pushrod-engined BMW R1200RS, the dohc eight-valve fuel-injected engine is tuned for a maximum output of 128 horsepower (95 kW) at 8,400rpm. The HP2's engine was the most powerful "oilhead" motor[3] before BMW introduced liquid cooling for some of its flat twins in 2012.
At 178 kg (dry) and 128 hp, the HP2 Sport is even lighter and more powerful than the R1200S on which it is based.[4] Its frame is tubular steel, like that of the R1200S, but the latter's tubular rear subframe is discarded in favour of a lightweight self-supporting carbon fibre semi-monococque seat unit.
The HP2 Sport is very well specified, with a quick shifter fitted as standard, Ohlins suspension and many carbon fibre body parts. Front brake calipers are Brembo "race-spec" Monobloc, wheels are lightweight forged aluminium, and tyres are Metzeler race compound items.[5]
Reception
The HP2 Sport was very well received. Motor Cycle News declared it to be BMW's "finest sporting package ", adding, "it is a lot of bike with a serious amount of performance goodies ... Not only does it make a brilliant road-going bike, the BMW HP2 will cut up rough at track days.". [6]
BMW HP2 range
BMW produced two other very different HP2 machines, the HP2 Megamoto of 2007-2010,[7] and the HP2 off-road machine of 2005-2008,[8] neither of which were as well received as the HP2 Sport.
