Sir:
I think you may have unintentionally posted the wrong model of aircraft engine.
The PT-6 series of engines are turboprop engines - the power is delivered to a shaft at the front of the engine, and a propeller is then attached to that shaft.
It would not be practical to use this type of engine to power a motorcycle because the torque (rotational force) applied to the propeller would also be equally applied to the motorcycle to which the engine is attached. The result would be uncontrollable.
I am going to guess that you are most likely seeking some form of jet engine - likely a pure jet engine, not a high-bypass turbofan.
Good luck...
