I've been searching around for some info to make sure I'm ordering the correct parts. I understand that part number 639174 is the complete SKF kit for this bike. However, I did find the following thread which mentions 639172 also, as the outer part of the same bearing kit? I presume the kit above would include this, and perhaps SKF list their complete kits by inner race part number? Once again, analysis paralysis, but I want to make sure. https://www.ducatiforum.co.uk/threads/steering-head-bearings.1400/#post-13056
