Went with a motion pro sleeve 01-0094. Seems to have been multi fit to numerous bikes including the 03-05 r6 and the 98-08 r1. No housing modification required. Used an old grip for mock up purposes throttle tube is not short either. You can see by the picture that the white area of the tube has more plastic, which in turn gives a shorter turn to get to full throttle. Other then that no wrist adjustment for full throttle, that is about it.
