As BMW's flagship model, the large GS is the first to be equipped with a new boxer engine, a revolutionary technology that will undoubtedly breathe new life into BMW's motorcycle family. The R 1300 GS is scheduled for official delivery on November 4, 2023, and from 2024 onwards, more R models will follow, including the GS Adventure, RT, R, and RS. This series of updates undoubtedly demonstrates BMW's in-depth understanding and unique insights into the motorcycle market. 
Let's take a closer look at the new boxer engine for the BMW R 1300 GS. At the heart of this engine are two opposing cylinders, and even the ignition distance is alternating left and right according to the four-stroke principle. The two cylinders are optimally perpendicular to the direction of travel in the cooling air flow, the crankshaft is longitudinally perpendicular in the direction of travel, and in combination with the shaft drive to the rear wheels. Since 1923, BMW has adhered to this principle, which has been the same for them for a hundred years. 
Since 2013, the BMW Boxer has been water-cooled in areas with particularly high thermal stress. In this major evolutionary step, BMW also rotated the intake and exhaust by 90 degrees, switching from a single-plate dry clutch to a multi-plate oil-bath clutch, thus switching to a normal oil circuit. This change not only improves the cooling efficiency of the engine, but also further enhances the stability and durability of the vehicle. 
In 2018, BMW added a variable valve timing system called Shift Cam. This system can switch between two different intake cam profiles depending on the speed and load for partial and full loads. The application of this technology allows the engine to deliver more torque and power at low speeds, and to reduce fuel consumption at high speeds. 
For the 2024 vintage, the displacement will continue to grow with the next evolutionary step, increasing from 1,254 cc to exactly 1,300 cc. The number of rounds is made up of 106A 5 mm cylinder bore and piston and a 73 mm piston stroke are given. Compared to the 1250, the bore has been increased by 4mm and the stroke has been shortened by 3mm. The twin-cylinder engine continues to be feng shui cooled at up to 9,000 rpm. 
* The maximum output of the engine is 1455 hp (107 kW) at 7,750 rpm and 149 Nm with a maximum torque of 6,500 rpm. That's nearly 1250 horsepower more than 10 gs at the same rated speed, and 6 Nm more at 250 rpm.
According to BMW, torque should be significantly stronger throughout the rev range, especially in the actual range between 3,600 rpm and 7,800 rpm, where more than 130 Nm of torque is said to always be available.
This series of improvements and upgrades fully demonstrates BMW's deep strength and unique insight into motorcycle design and manufacturing. They not only continue to innovate and make breakthroughs in technology, but also strive for excellence and perfection in user experience.
