The BMW R 1200 RT is a popular touring motorcycle that has undergone significant changes over the years, including the introduction of a water-cooled engine in 2014. This transition from an air-cooled to a water-cooled engine has brought about several advantages that have made the R 1200 RT an even more desirable choice for long-distance riding.
The Transition to Water Cooling
Prior to 2014, the BMW R 1200 RT was equipped with an air-cooled boxer twin engine. This design was a hallmark of BMW’s motorcycles, but it had its limitations in terms of performance and efficiency. In 2014, BMW introduced a water-cooled version of the R 1200 RT, which addressed these shortcomings and provided a more advanced and capable powertrain.
The water-cooled engine in the 2014 and later R 1200 RT models features a displacement of 1,170 cc and produces a maximum power output of 125 hp at 7,750 rpm and a peak torque of 92 lb-ft at 6,500 rpm. This represents a significant increase in performance compared to the previous air-cooled engine, which produced around 110 hp and 88 lb-ft of torque.
Advantages of the Water-Cooled Engine
The transition to a water-cooled engine has brought several key advantages to the BMW R 1200 RT:
Improved Performance
The water-cooled engine’s increased power and torque output translate to better acceleration, higher top speeds, and improved overtaking capabilities. This makes the R 1200 RT an even more capable and enjoyable touring motorcycle, especially when navigating highways and mountain roads.
Enhanced Fuel Efficiency
The water-cooled engine’s more efficient design, along with the use of electronic fuel injection, has resulted in improved fuel economy. The 2019 BMW R 1200 RT is rated at 49 mpg (4.8 L/100 km) in combined city/highway driving, a notable improvement over the previous air-cooled model.
Reduced Emissions
The water-cooled engine’s more advanced design and the use of electronic fuel injection have also led to reduced emissions, making the R 1200 RT more environmentally friendly.
Improved Reliability and Maintenance
The water-cooled engine is generally considered more reliable and easier to maintain than the previous air-cooled design. The wet clutch, for example, simplifies clutch replacement, and the overall engine design is more robust and durable, with many owners reporting their bikes lasting over 100,000 miles with minimal maintenance.
Technical Specifications
The 2019 BMW R 1200 RT with the water-cooled engine has the following key technical specifications:
- Engine Displacement: 1,170 cc
- Maximum Power: 125 hp at 7,750 rpm
- Maximum Torque: 92 lb-ft at 6,500 rpm
- Transmission: 6-speed
- Fuel Capacity: 6.6 gallons (25 liters)
- Wheelbase: 60.7 inches (1,541 mm)
- Seat Height: 32.3 inches (820 mm)
- Dry Weight: 579 lbs (263 kg)
Maintenance and DIY Considerations
One of the benefits of the water-cooled R 1200 RT is its relative ease of maintenance compared to the previous air-cooled model. Many owners report being able to perform routine tasks like oil changes and tire changes themselves, thanks to the more accessible design of the water-cooled engine.
That said, it’s important to follow the manufacturer’s recommended maintenance schedule and use the appropriate tools and fluids to ensure the longevity and performance of the water-cooled engine. Regular inspections, adjustments, and replacements of components like the coolant, hoses, and water pump are crucial for maintaining the bike’s reliability and performance.
Conclusion
The transition to a water-cooled engine in the BMW R 1200 RT has been a significant upgrade that has improved the motorcycle’s performance, efficiency, and reliability. The increased power and torque, enhanced fuel economy, and reduced emissions make the water-cooled R 1200 RT an even more capable and desirable touring motorcycle. With its relative ease of maintenance and the potential for long-lasting durability, the water-cooled R 1200 RT has become a popular choice among both casual and DIY-inclined riders.
