Dear Mr. Know-It-All,
My 2021 Beta 250RR Race Edition’s rear shock literally came apart at the top of the shock body. I notice there is a seam where it broke. All of the oil had blown out of it in the process. What could have caused this?
This is an unusual missive, so we put in a call to the Beta tech folks:
“There are rare instances when tightening down the lock ring on the Sachs damper after re-setting the spring tension can inadvertently twist the shock body, causing the two body pieces to come apart. My suggestion is this: when you lock down on the top ring, snug it by hand. Hold the lower ring in place (with the proper adjustment tool or a large set of channel lock pliers) and carefully set the top lock ring with a gentle tap with a punch. You want it to wedge into the lower ring, but you do not want the lower ring to twist as you set the top ring.”
