When it comes to new cutting edge high performance technology, the 1K is the machine. Even with my K6 1K I am very suprised at the performance factor vs. Busa. I couldn't believe how hard it pulled out of the corners and how fast it got up to the limiter. It definitely needed some sort of traction control. Although I do not think the K7 has a TRUE traction control. Usually those units have a speed sensor on the front wheel that sends that info to the ECU and matches Rear wheel speed. If Rear wheel exceeds front wheel speed, TC cuts a cylinder and/or retards ignition so the tire always stays hooked to the ground.
The K7 just has 3 different powersettings from what I understand.
