Torque specifications
Created:
Updated:
// //
Factory and after market manuals provide some torque settings for loop frames, but they are far from comprehensive. John Schwartz sent me a list of factory torque specifications that are for V7 Sport, 850 T, and 850 T3 motorcycles. From John: Most of them will apply if you understand Italian!!! and the translation.
While carefully transposing this file, I noticed what I perceived to be several mistakes. I did not correct them, though. I chose to leave any corrections up to the end user's discretion. What I perceive as missing or incorrect values are highlighted in yellow.
