Hello people, I have a question. I have two 1100 D models standing in the garage. one is built 93 and one 96 How does that happen that the 96 is registered with 270kmh and the 93 with 246kmh ? What is different about the older one? But it seems to me that the older one pulls much better than the 96. Can it be that the 93s has less scratching??? thus better pulls but less final speed? The 96 goes according to tacho a little over 300kmh but does not pull like the 93s… Can it be n with the pinion???
