Exclamation BMW's History of The Duolever or Hossack

Let us not discuss the name, we know what it is rightfully called: Hossack!

But take some time and enjoy this:

The Inovative Duolever Frontwheelsteering of The K1200S, from concept to Reality.

You might go get your dictionary as it is in German.

Re: BMW's History of The Duolever or Hossack

Hossack's design putting the spring/shock on the front wheel carrier removes a lot of the heavy suspension loads off the lower A arm. While unweildly, I think it's the better design and I wish BMW would have made it work that way. Although from a packaging standpoint, the current design is very compact.

Re: BMW's History of The Duolever or Hossack

True, very true... When I first took a mosey around the front end of a new K-series (at a South African bike show in 2006), I was astounded that so much of the front suspension should be made of pretty hefty chunks of forged steel!!!

However, at the AMID bike show in 2007, I saw a full carbon frame / front suspension setup at one of the smaller stands that also uses the Hossack design - no BMW components anywhere in evidence.
Can't remember who built it... it might have been done as an engineering exercise, to gauge public response.

Re: BMW's History of The Duolever or Hossack

Indian was running girder front ends in the 1930's. I saw H-D chops back in the 50's running them because they both worked and look cool as hell. Are the new ones better? Of course they are, but Hossack did not invent them.... Look at a 1939 Indian Dispatch.
