| I understand the gesture to offer gearing advice to a fellow Ducati owner based on your own experience, but some of you are missing an important point. Different Ducati models have different different red-lines, primary drive ratios and different transmissions. So they require different sprockets.
First, 916’s and 996’s both have the same standard-ratio transmission, but the 916 has a 2:1 primary drive ratio where the 996 has a 1.84:1 ratio. So the answer to the initial question about the best gearing will be different for the 916 and the 996. Which model is it?
Second, (if his profile is correct) dave w drives a 999 that has a 1.84 primary drive ratio and a close-ratio transmission, which is a set-up that has a different overall gearing and gear spacing than either the 916 or the 996 in question. So a positive result with a particular sprocket combination on a 999 doesn’t translate to a model other than a 998.
If you convert his 999 recommendations to a 916 set-up then the recommendation become 15/37 to 15/42. For the very highly geared 996, the closest you can get is with 15/42 to 14/42, but I strongly suggest that you not use 14-tooth sprockets on 99s’s, 998’s or 999’s because of higher chain tension.  |
