Hi Roo

Bought them along  long time ago for my CB400F but they are for the modern Honda CB 400 super four and not a CB400F

There's some interesting ideas, components etc being used in mtb forks, particularly downhill type equipment currently. This make started in 32mm with later going to 35mm then 37mm. Whether any of the caps etc use the same spec you'd have to check though.

Measuring the top I think they are for fork stanchions of 41mm diameter but different manufactures have different internal threads for the same fork dia
