Is there anyway of making a 200x57mm fit?

It will fit straight on. The trouble will/may come once the shock has travelled past the 51mm mark. Does the suspension have room for extra travel?

Thanks legend. I haven’t purchased the frame but have the 57mm shock. I’m thinking surely there must be 6mm clearance to play with before linkages start hitting tubes. I might buy it and see.

The linkage may ‘bottom out’ before the shock does, which may lead to you snapping some sort of linkage. Really depends upon the design.

As above.

Worked fine on old Hecklers.

Worked a charm on the Blur 4x too, I’m told – the extra 6mm bumped it up to around 130mm travel.
