All you need to know about BMW Motorcycles 2012 K1600GTL
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.”
Chain-driven cams actuate the four-valve heads of the, let’s do the math, 24-valve design. BMW touts the cams are compression-molded on the tubular shafts in a process that, compared to “conventional clear-chill cast or steel camshafts,” shaves off an extra 2.2-lbs. The magnesium valve and clutch covers also aim to trim the pounds - though we’re betting these new Beemers aren’t exactly going to be featherweights when we toss them on the scales as the claimed curb weight is conspicuously absent in the PR material.
Ride-by-wire, which BMW dubs E-Gas, controls a central 52mm throttle valve. Riders will choose from three engine modes – Rain, Road and Dynamic – which are selected via button at the right-side handlebar.
One new development showcased on the K1600GT is what BMW describes as “the first ever ‘Adaptive Headlight’ for motorcycles.” The standard issue Xenon light works via a movable projector that shines onto a mirror. Sensors at the front and rear axles detect the pitch of the bike, with the projector moving to compensate and provide a permanently level headlight. The “Adaptive Headlight” goes one step further, with the mirror itself turning on an axis via stepper motor. A sensor box (used in the S1000RR) relays banking angle, which is then fed through the electronics and adjusts the mirror to keep a level projection beam no matter the lean of the bike.

GT stands for Gran Turismo, so both are tapped out as purpose-built tourers, but there are differences. The GTL is pegged as the heavy-duty luxo-tourer, with a standard top-case and more pronounced pillion amenities. Rider ergos are also different, with the regular GT sourcing an “active seating postion,” which we interpret as a little sportier than the “relaxed, upright seating position” of the GTL. Elaborating on the ergo difference, BMW notes the GTL’s handlebars are positioned further back with the footrests further forward and lower.
