All of the old parts I have here show about 16mm of engagement, with 4mm unused spline in the hub. The R1100 5-speed has 18mm engagement.

FWIW the input shaft for the Hexhead has the identical profile with a 4mm longer clutch spline... but the rear end is too long with flutes that keep you from machining it to fit. So close...
