Conclusion:
In other words, the K1300GT has 5.5 per cent more wheel torque per kg available at the back wheel than the K1600GT at 100kph (62mph), and 10.7 per cent more than the GTL. So despite the engine specs, the GT is the faster top gear accelerator at these speeds.
On top of this, further factors need to be taken into account. One is the 1600’s larger frontal area, which means more drag to overcome, and as the speed builds this becomes very significant because drag increases with the square of speed. The second is the nature of the power delivery: the K1300GT has quite an aggressive throttle response compared with the six-cylinder bike’s sophisticated, smoother response which softens the initial acceleration.
