That might possibly work, any idea where I could buy about 6‘ from?42.4OD handrail no good? Aka Tube Clamp size C.

ETA. I see Brundles sell it in 2m lengths. For what it costs I might order a length and have a play.
West Midlands, near J14 of M6.I've used Brundles occasionally.
Whereabouts are you?
I thought the same initially, but any steel tube 43 OD by 3 mm wall thickness has to be of a minimum strength, no matter how chinesium its metallurgy, also to even be certified as suitable for handrails.Knowing nothing about the spec of the tube used for handrails, it wouldn't necessarily be my first choice of material to keep me off the ground at anything over 5mph
Er, not a lot... if you have a cnc miller, a stock of alloy billet and the know how.Not a lot to making yokes.
But if you want close to fitting together yokes n tube, try 1-5/8" tube and 41mm yokes.
easy enough on a manual mill, but quite time consuming. And obviously you need a mill.Er, not a lot... if you have a cnc miller, a stock of alloy billet and the know how.

that aside….for a leading link front end you could have the yokes cut by water jet or plasma in steel then weld in legs,
Kawasaki ZZR1200 has 43mm upper stanchion tubes,
Kawasaki ZX12R has 43mm x 505mm lower stanchion tubes
Kawasaki ZX14 has 43mm lower stanchion tubes.
If I were to fabricate the yokes I’d do it in steel, using whatever size tube was readily available somewhere near my carefully guesstimated size and strength requirements.CNC! I used an Archdale drill, band saw, dreadnought file and bundles of
elbow grease to make yokes for a TZ750.
I haven't made any yokes since I got a mill.
I mentioned the tube n yokes as they were common tube and fork stanchion sizes that nearly
go together; the wrongness being on the right side.
If your going to use new tube your probably going to have to buy fractional sized tube?
1-3/4" tube into a 43mm hole sounds like a non starter.
1-5/8" tube only needs few thou removing to get it into a 41mm hole, removing the few thou should be OK with no machines.
You could fabricate the leading link legs from random tube and some 43mm fork leg?
Or make the forks from smaller than 43mm tube and bush the yokes?
