The reason for the 955i's excessively long throttle twist is this eccentric cable drum located on the EFI deep inside the engine bay. Note that the first portion of throttle grip movement will only actuate the throttle plates so far (probably to help alleviate off/on throttle abruptness common to fuel injection), then increases significantly as the throttle is opened up more than halfway.
