Not that long ago I was groaning at them being £75! 😡

It's hard to justify £130 to the 'bank manager'
😂😂😂

An alternative would be plated ones on the front to match the rear? Would they be good enough to replate?

The DS ones are BZP aren't they, mine are too far gone and even then the tine involved plating 40 spokes and nipples with my small kit makes the DS ones price attractive

I tend to agree Dom, even with a set in good condition it would be quite a tedious job. Never done a set myself, just bought a replacement stainless sets. Time to talk the “bank manager!” 😂

Here's a question for Bryan or anyone else that knows the answer, I picked up a cb550 hub from Bryan last week which is the version without the flats on the speedo side, what is the real difference if any when used on a single disc set up?

Single disc none at all, you use all the same bits in same places speedo drive is driven by the chrome plate and bolts

Cheers Bryan, what was the change for then?

OK, final question, what was the purpose of the machined flats that were seemingly not required?

On the first CB 750 the speedo drive had two turned down flaps that engaged with the slots to turn the drive gearbox and the chrome trim was flat, aparently the speedo needle wandered due to not positive enough drive so honda modified it and i guess just did not get arround to altering the hub drawings till years later
