If the gear shifting of the S 51 Enduro no longer works, there are a few potential solutions. First, check the gear shift linkage and cables to ensure they are not damaged or misaligned. If they are, they may need to be adjusted or replaced. Additionally, the transmission fluid levels should be checked and topped off if necessary. If these steps do not resolve the issue, it may be necessary to have a professional mechanic inspect the transmission for any internal issues or damage. **
