FYI, for future ST1100 owners that this may happen to...
The plastic speedometer gear on my 2001 ST1100 ABSII broke. One of the two tabs was broken off. The gear just pulls/slides out of the housing. A few pics below...
I have a spare wrecked 2001 ST1100 non-ABS, so I pulled the speedometer gear assembly off of it. The plastic gear p/ns are different between the ABS and non-ABS. The ABS gear has 24 teeth whereas the non-ABS has 22 teeth. The housings are identical, not sure about the internal metal pinion gear though. Since I had it in hand, I disassembled, cleaned and lubed the non-ABS assly and installed it on my ABS bike. Works perfectly... speedo reads exactly the same as before... about 1 MPH low at 60 MPH, according to my GPS.
Lubrication consisted of cleaning all parts and using some general grease to lube the ID and teeth of the plastic gear, a little heavy on the teeth. I didn't see anything in the Honda shop manual about maintenance of this part but I plan to clean and lube every tire change or two... only takes a few minutes.
