The K1600GTL truly combines a level of comfort, convenience and performance that have never before been brought together at such a level.The lighter, sportier K1600GT, meanwhile, aims squarely at a richly varied sport-touring market that includes the Ten Best-winning Kawasaki Concours 14, Yamaha FJR1300, Triumph Sprint GT (and a spied, larger sport-tourer expected in 2012), BMW's own R1200RT flat-Twin, plus crossover bikes like the Ducati Multistrada and Triumph Tiger 1050. We rode the GT after spending a long day on the GTL, and the difference in riding experience was surprising. The sportier riding position, taller seat and narrower, shorter screen gave an overall lighter, more aggressive relationship with the bike and, therefore, the road. While the top-trunk-quipped GTL can be rolled into corners quite swiftly, the GT snaps right down to its footpegs. Claimed weight (again with 90-percent fuel but without the easy-to-remove bags attached) is 703 lb. Not light by any means, but the stiffer settings for ESA II kept composure to an impressive level. The higher, more-rearset pegs allow greater cornering clearance, and chassis feedback is very good for a bike of this size. After the footpeg feelers were worn away, the sidestand-deployment tang began to kiss the pavement in left turns. But the feeling of security and control at the limit was fantastic.
