Yes 12 pulses, i did an article for Pronto about it a while back
Here is the summary
From my findings you don't need a special trigger ring and the trigger points do not have to be evenly matched.
Use Allen bolts as disc fixings and as trigger points, these will generate 12 pulses per rotation.
For a 120/70/17 Pirelli tyre use an input figure of 10344 for MPH speed-readings.
For a 120/70/17 Michelin tyre use a figure of 10427 for MPH speed-readings
I also have PDF copy of the manual if you don't have one, if you need it just send a email request to firstname.lastname@example.org
