;Pre-2017<br />
: The motor shaft is keyed; the key has a square cross section.<br />
:;Measurements<br />
:* Dimensions seem to be ¼” square ⨉ 2.0” length (expressed in metric on drawings).<br />
:* Ends 5mm from shaft end.<br />
:* Shaft diameter is ⌀28.275mm+0-0.021<br />
:* Shaft length extends 66.675mm beyond the motor face minus 4mm for raised parts of the face.<br />
: 2013 models had a minor [[Recalls|recall]] about the shaft key coming loose, but this was a design revision that has not recurred.<br />
;2017+<br />
: The motor shaft is splined to allow higher torque transmission.<br />
: Rumor has it (via [http://electricmotorcycleforum.com/boards/index.php?topic=7010.msg59925#msg59925 Harlan at Hollywood Electrics]) that the spline is supposed to match a Kawasaki KX250F as well as a Yamaha YZ450F.<br />
