Study of the geometry suggests there may be conflict with the steering arrangements during suspension movement?

And indeed that mounting the hand control pivot elsewhere might not only resolve that but also delete some components and increase steering precision.

Finally it's worth noting that all PTWs will at some point be picked up using that hand control and accomodating the loads incurred at the design stage may avoid unpleasentness later.

Apologies if this has at any stage polluted anyones creativity...
