Motorcycle sprocket tooth fractures
Motorcycle sprocket tooth fractures
(OP)
This was coincidentally (and probably luckily) discovered while a Ducati 1098 was being routinely cleaned. There were no symptoms, noise and reportedly no abuse. Chain and rear sprocket were in good condition, i.e., not damaged at all. It looks like the damage on the 3 involved teeth were perhaps due to fractures. Oh, this was a factory OEM standard part. Would anyone like to comment on this?

14 teeth is usually OK. More is better. I think most chain design manuals would warn about 12 0r fewer teeth due to the drive radius (and torque and tension) variation as each tooth receives a roller.
Note there are at least 2 problems here for which "too small sprockets" might be blamed.

This suggests minimum 17 teeth for industrial applications.
