The Propeller brand has made good on its promise to extend the K series with the six-cylinder powerplant by announcing its K1600GT and K1600GTL touring motorcycles.
The Inline Six configuration has been used extensively throughout the Bavarian marque’s automobiles, but is now showcased on the two-wheeled side. The new engine features a 1649cc displacement via the undersquare 67.5mm bore x 72mm stroke. The Inline Six layout keeps the same 55-degree forward tilt of the four-cylinder K series engine and despite tacking on the extra two cylinders the new Six measures only 22-inches wide. With its narrow dimensions and 226-lb weight, BMW hails its new mill the “lightest and most compact six-cylinder engine in serial motorcycle production.
The BMW Inline Six for the K1600GT models is only 22-inches wide, with BMW claiming it's the "lightest and most compact six-cylinder engine in serial motorcycle production."
Peak power claims are 160 horsepower at 7500 rpm and 129 lb-ft of torque at 5000 rpm. And that ample torque will churn out quick, with BMW promising 70% of peak at 1500 rpm. The information released on the K1600 models doesn’t list a specific redline, but the previous Concept 6 described the new mill as revving “almost to 9000 rpm"
