1st spring clutch automatic !!!

What have you got there Michel? Those springs look very different.

Must have found the pic on the net !!!

I wonder why Husqvarna doesn't offer the auto tranny today. I think they sound awesome.

I know my Polaris quad with the snowmobile variable clutch was awesome. It gave me more time to pick two lines in the trail the machine did the shifting.

That is pretty easy to answer. Husqvarna today is a linkage version of xcw ktm. I might be a couple of years behind though.

Sure those are not the ones you had made up?

So the Husqvarna dirtbikes are like the KTM dirtbikes there cousins like the firebird and camero?

more like the ss is a comero model

Husky is now the redheaded stepchild of KTM. The shame...

just to clarify Bill, huskies are ktm engine + frame units with slightly different fork and shock specs and plastics.

huskies use exclusively the kato sx shock linkage system in the rear suspension while kato exc still use the direct shock system (brain fade)

Getting back to the 1st gear springs I have always wondered what would happen if a person redesigned the setup so it looked more like a chainsaw clutch.

i think the rekluse type clutches kind of killed the auto type thinking.

Unfortunately, it think you are right. Just like video killed the radio star.

What do you think of a modern day Rekluse Z-Start Pro or EFM style primary clutch setup. A clutch out of the Husky(BMW era) 449/511 where the clutch is on the end of the crank, would take a whole lot of fiddling around and a machine shop at your disposal but I think that would be the final answer. Does anyone think it would be possible?

The auto concept at least like in the picture in post 1 got going from military research the way I understand it.

As to the future the current electric bikes I am aware of do not use a transmission. The Zero salesman in Enfield Ct had a real attitude like why would I want a transmission? The deceleration or engine braking forces can be accurately controlled or should be able to soon.

Then there is the ivt infinitely variable transmission.

The latest KTM redesign of the two stroke 250-300 seems to put a lot of emphasis on center of weight and likely center of rotating mass. Probably that is going to be hard to beat in a competition environment. I have even heard the logic that the main advantage of leaving the dual shock set up is mass placement.

Hi! The photo is mine... the springs are specially made at the Husqvarna Motorcycles R&D dpt back in the days, thicker spring material to stop cracking at the "connections" and ground down coildiameter to get correct springload. Bike will be up and running in a month or so after a complete renovation. Regards Mikael Zetterlund

" back in the days"

Does this mean at the time they had a real hook on each end like the ones pictured or at a time of the last design that come in the kit for the first gear/crankshaft clutch pictured.

How many auto must I add in the thread ?

There was a lot of work going on at the same time, in order to overcome the breaking springs, this type was one attempt and the other type of springs "without the hook in one end" was another. Since grinding down the outer coildiameter required delicate manual work I assume the other solution was chosen for the replacement-kits.
