2008 rs vector gt 121 in mono rails

[gamemaster]

Do these rails crack like the 136 mono does quite often? How common do they crack on the 121"? Thanks

I have seen them stress crack right between the stiffeners. Have a few of them here that did that.

Mine has been cracked for years on my 09 121.

I’m surprised they last as long as they do… none of the holes or upper edges have very good chamfers. A little machine work would probably increase the life dramatically.

Were are they cracked? It doesn't get worse? Thanks

My cracks haven’t changed, my cracks are located on the top of the rail right below the pivot for the front swing arm.
