I know about sliding pillar Peter, but sliding hub is a new one to me, car to explain what it is?

The Morgan suspension, commonly called sliding pillar, is actually a sliding hub. The pillar is fixed, the king pin, the hub slides on it. There were other systems in which the hub was fixed to the kingpin and the whole assemblý slide up and down in bushes fixed above and below.

Peter. The BMW Telelever front suspension is an English invention by Saxon-Motod. It is an excellent system and I am surprised that other manufacturers don't use it.

PS. I should also have mentioned that the Earles fork used on many vintage bikes and more recently sidecar outfits is also an English invention.

Peter,

I think BMW patented it or have, in some way, IP ownership. There was some negative noise in the bike world 10 or 15 years ago to the effect BMW "stole" the design and the English inventors got little or nothing.

I agree, it works very well: the inherent "anti dive" nature is a delight on a bike.

Peter, I think you are referring to the BMW Duolever system which was a copy of the Hossack design, introduced on the K1200S.

It's interesting the BMW are moving back to conventional USD forks on some of their latest bikes, the new R1200R and the R1200RS.

The late and greatly-respected motorbike journalist Kevin Ash was testing a BMW R1200 GS when he had his fatal accident.

The BMW Telelever is a variation on the original Saxon design. If I recall correctly in the end BMW did pay for rights. How much and in what way I do not know. Actually I believe Yamaha also used a Saxon based system on one of their bikes.

Then another British design, the Hossack system. It is interesting that BMW have used three British developed anti-dive systems; Earles, Saxon, and Hossack.

As an interesting comparison check out this system developed by Guzzi about 80 years ago.
