New front fork design - evolution or revolution?

You want something "special" made?
I thought you only owned Montessa's

Makita make bikes now???

i think the idea behind those forks was to achieve 2 sets of preload so as when a seto of whoops is hit the is still some shock left after the first whoop

Walter,

I seriously doubt there's any diff compressing two springs at diff ends, unless theres two diff dampers in there too.

Otherwise it seems to me to be the same as two normal split-rate springs but w a whole lot more unsprung weight.

Perhaps you can have 2 sets of preload, but you've still got more unsprung weight to deal with.

the guy reckons he built it cause arm pump was killing his racing, and reckons using this fork, he gets arm pump no more, like zero pump, ever.  how handy would that be?

The only advantage I can see , is that you could play with the two different springrates for different tracks and weather conditions . But how many will go that far ?

After the work week from hell I finally have a chance to follow this.

Walter, I owe you an apology, I'll get in touch probably tomorrow as I've got a "dinner party" to go to. Just what I need!

I can't see what these double forks could do that normal forks couldn't.
Two spring rates? put two springs in normal usd forks.
Two damping rates? halve the damping chamber size and use two of them. But a well designed shim stack should do the job or you could use, as Nathan said, a PD style set up.

What I can see is two more seals, a I understand that modern seals are prone to leakage.
Two more points of movement, sliders, tubes etc. This give would give less rigidity and there would be, I imagine less overlap between the inners and outers.

The guy's done a great job and I love this type of engineering but I can't see too much advantage to it.

Having said all that I'd still love to see what's inside!

Brent you covered most points , but you just never know . Maybe we will  hear more of it.
We recently played with water shocks , perhaps thats crazy too  . But I remember when we made the first Hi Low Speed shock for road racing ( Glenn Ritchards)and the Ohlins camp told everyone there is no need for such thing ....
