Suspension strut Yamaha YZF-R/MT 125, from year 14

A worn rear leg can be noticed quite quickly, even if the rear swings when tilting in curves. In addition, a leak at the upper oil ring is often visible, which spreads oil over a large area on the swingarm and possibly even on the rear wheel. If this is the case, you should act immediately, especially for safety reasons. Since a repair is not possible, the only solution is a complete replacement.
