In the first year of BMW, they introduced a rule book and took us directly to the Adventure R1250GS. Marcque Germany usually waits 12 months before the Adventure model launch, but with GSA sales now on par with GS standards, new engine bearings have saved us. So what’s new? Same with GS basically. The GSA gets a new 1254cc boxer distribution from GS, which gets a 9% power increase to 134bhp and a 14% increase in torque to 92ftlbs, making it the strongest boxer produced by BMW. The GSA also accepts ShiftCam from GS, which changes the timing and steps of the intake valve to increase power distribution in the rotation range, as well as reduce fuel consumption and emissions.
The GS code is the main pedigree of BMW Motorrad with many successes over the years, and this is the main lineage of the German adventure family 2019 BMW R1250GS Adventure. The engine is a new engine that is coming. With a variable valve or in a camp called ShiftCam on the 1,254 cc twin boxer engine that provides 134 horsepower. Various electronic systems There are two standard equipment such as Hill Start Control (HSC) and Automatic Stability Control (ASC). Options like Riding Mode Pro add driving modes like Enduro and Enduro Pro. ABS cornering is present on behalf of the Pro ABS LED headlights are standard equipment. The 6.5-inch TFT screen, a large tank of up to 30 liters, makes this car weigh nearly 270 kg. When adding more liquid, the standard version is 7.7 kg. A larger oil tank makes the whole car look bigger. With a long impact from the bottom of the long air intake to the side of the engine.
The HP R1250GS comes with a White / Blue / Red Racing paint job with a white frame, matt black engine, black Telelever tube, and black handlebar. The HP model is also standard with gold wire and brake calipers. The HP GS can also be upgraded to an optional sports suspension designed for off-road performance. Updates (which are only available with the Dynamic ESA option) add longer struts with increased spring rates. The longer suspension increases the seat height to 35.4 inches compared to the standard seat height of 33.5-34.3 inches (lower 31.5-inch seats are also available).
This new engine is BMW’s first VVT application on motorbikes, joining people like Honda, Kawasaki and, more recently, Suzuki and Ducati, in introducing several forms of technology. BMW iteration uses a single intake camshaft with two cam per valve with an actuator that shifts the camshaft laterally to choose which cam set is being used. The smaller partial load cam provides increased lift to the intake valve to increase fuel consumption and refinement at low speed. At higher engine speeds, larger cams enter, maximizing valve lift for optimal performance.
The R1250GS model is 84cc larger than the previous 1170cc engine on the R1200 motorbike. Greater displacement is achieved by increasing the cylinder hole to 102.5 mm from 101 mm, and the stroke to 76 mm from 73 mm. BMW also introduced a slight phase shift to the intake valves so that they open to different levels in a staggering sequence. This creates a rotating effect to the air-fuel mixture for more efficient combustion. The Model R continues to use a coolant mixture of air and liquid with coolant that targets the cylinder head. According to BMW, this change combines an increase in torque in the rotation range which reaches speeds of 105.5 lb-ft at 6250 rpm (the previous engine claimed 92.2 lb-ft.). BMW also boasts an increase in power output, claiming 134 hp at 7750rpm, compared to claims of the R1200 123 hp engine. Changes also result in a 100 rpm reduction in idling engine speed, lower emission levels, and, said BMW, optimized sound and 4% lower fuel consumption.
