This is the maintenance schedule and service intervals for the BMW K 1600 GT, BMW’s most premium sport tourer.
It’s also the same maintenance schedule for the BMW K 1600 GTL, and the BMW K 1600 B (and the Grand America), which are the same basic motorcycle but with different accessory options and slightly altered comfort levels.
The BMW K 1600 bikes are all based around a forward-canted inline six-cylinder engine that makes peak power of 118 kW (160 hp) at 7750 rpm and maximum torque of 175 Nm (129 ft-lb) at 5250 rpm — a crazy high amount of torque.
The original 2011-2016 BMW K 1600 GT was revamped for the 2017+ BMW K 1600 GT (and GTL etc.) with new style, many options becoming standard, and Euro 4 compliance, but the power and torque specs stayed the same.

About the BMW K 1600 GT
The BMW K 1600 GT is the full-dress tourer from BMW, a competitor to the Honda Gold Wing.
It’s similar in concept — a bike with no luxury spared, and a six-cylinder engine with huge torque and very high reliability.
The K 1600 GT has always had a very powerful six-cylinder engine that would be at home in a medium-sized car. And since the bike it’s pulling is no lightweight (weighing 319 kg for the GT without panniers, and 348 kg for the GTL with panniers and top case), it’s just as well.
The K 1600 GT is also obviously a very comfortable bike. It’s comfortable not just for the rider but also for the pillion — particularly the GTL, which comes with a top case and backrest.
The K 1600 GTL is the same basic bike as the GT, just with more comfort. The riding position is more upright for the rider, with the handlebars closer, and the rider’s footrests are further forward to press less strain on the knees. In addition, the standard top case also acts as a back rest for the pillion passenger.
From the time it was launched in 2010 for the 2011 model year, the BMW K 1600 GT/GTL has had extremely high technology spec.
Even in 2011, the BMW K 1600 GT and GTL came with full ride-by-wire (then called “E-gas”, power modes, dynamic traction control, and a full TFT display, and with options like electronic suspension adjustment, an adaptive headlight, and cruise control.
In 2016, BMW released a revised K 1600 GT for the 2017 model year. It had the same engine and power and torque specs, but BMW had updated it to make sure it met Euro 4 emissions restrictions.
In addition BMW added to the 2017+ BMW K 1600 GT:
- ABS Pro and Dynamic Traction Control — BMW’s cornering ABS and lean angle-aware traction control technology
- Many things previously options now standard, including heated grips, cruise control, xenon headlamps, and more
- Reverse assist (an option)
- Electronic suspension Dynamic ESA as standard — automatic damping, updated from ESA II (previously an option)
- Intelligent Emergency Call — an option to make a call in case you have an accident
- Newly designed instruments
- Enhanced fairing for more wind and weather protection (revised styling, basically)
- Optional quickshifter (Shift Assistant Pro)
Since 2017 there have been no updates to the BMW K 1600 GT and GTL other than releasing the K 1600 B (Bagger) and K 1600 B Grand America, two different accessory/style options, with the Grand America coming with everything (even reverse assist as standard).
