BMW Motorrad has pulled back the curtain on two new ultra high-end touring machines at the 2010 Intermot show in Cologne, Germany.

The K1600GT and K1600GTL are two highly sophisticated touring rigs and are the first to use BMW’s new 6-cylinder engine that first appeared as part of the Concept 6 study in 2009. BMW claims that the 226 pound engine is the world’s lightest and most compact production 6-cylinder in-line engine displacing over 1,000 cc. Claimed to produce 158 horsepower, we’re more impressed by its torque: 129 lb-ft  (70 percent of which is apparently already available at 1,500 rpm).

Separated by their touring personas, the 703 pound GT is described as having “ergonomics for proactive touring” (we’ll take that to mean it’s sportier). For the more serene tourer, the 767 pound GTL features a more relaxed set-up and greater comfort for longer trips.

Both versions use a ride-by-wire throttle system and feature a 5.7-inch TFT color display (as used in televisions, computer monitors and cell phones) for its instrument panel.

The list of optional gadgetry for the two motorcycles is dizzying. There’s a three-mode DTC (Dynamic Traction Control), the three-mode ESA II (Electronic Suspension Adjustment), and the first ever adaptive xenon headlight system that not only self-adjusts for varying loads (pitch), but also remains level while the motorcycle is leaning in a turn.

BMW will announce Canadian pricing for the new models at the Toronto Motorycle Show which runs from December 10 to 12 at the Metro Toronto Convention Centre. Stay tuned for more news on BMW’s exciting new big rigs.
