| Andy,
All I'm doing is relaying the details. The "majority" of the faults happen on the rear rockers and it seems to be more "common" on 748's. That's not to say that it doesn't happen in other forms on other bikes.
As for theories that's all anything is. However as Sigma see a few bikes and know a thing or two, I'd trust their evidence based experience.
p.s. how were the rest of yours holding up?
Cheers,
Simon |
