Mono shock and fork conversions

Here’s were this get beyond me. Is the square cross member more resistant to twist than the round One?

Regardless, that is a perimeter style frame and also it cracked near the head-stock not the upper-shock mount, so i really don't see how that is relevant at all, unless you are trying to push your "motorcycle engineering peaked in 1978" ideology.

The early oil boiler frames is what i'm talking about. 1986-1988. The frame design is similar to the tubular steel frames that preceded it so it is a good reference point when adding a mono shock.

Thanks for the answer. I wasn't trying to push any ideology at all. I am very unfamiliar with Suzuki bikes, so I was trying to learn if the type bike you mentioned used the same frame technology since it uses the same GSXR name. I'm glad to see that the new GSXR frame is very different that the old style GSXR frame. Incidentally, I'm not sure why you are under the impression that I have a "motorcycle engineering peaked in 1978" ideology because for sure I do not believe that is true at all. Ed

This will be my bolt on mono shock conversion for the next winter. ( GSXR engine swap? )

That is a nice adapter kit, It does seem that there is something add to help with that torsional load whenever this type of offset tab is used. whether its a lower gusset like the older GSXR or as in this adapter featured below. This adapter looks close to what I had done, With exception of thicker shock tabs but it also seems to me that the torsional load is being transferred forward and back down to the frame by way of the motor mounts plates. Correct me if I'm wrong... PS,I bit those speed hole add a lot of Horse power...JK.
