Truckers Monster Rebuild

What about it looks make the beast with two backsed up?

Looks totally functional to me.

On first view, I thought that the back-leaning angle of the pushrod would make the linkage prone to binding.  Looking at it now I think that's unlikely and it's probably just progressive linkage, although I have some concerns that the curve may rise too much.

I'm no expert on suspension geometry, but that linkage on the swinger looks kinda f'ed up to me.

Then why say anything?    

[Buckethead]

Maybe he was hoping for an explanation? You gotta admit, it IS a pretty funky design.

[truckinduc]

The design is a very slight rising rate. The pushrod angle vs rocker angle vs shock angle naturally make it get stiffer as it compresses also.

Without tuning it seems to be working rather well. I still need to have the shock pressurized though.

here is a short video that may help clear it up.

the line in red is the progressiveness.

is that how stiff the rear should be? i always thought 25 mm sag. not sure if its just a lack of a visual vertical reference point thats making me think its stiff. or maybe my 25mm is a lame soft street measurement and your more track oriented.

looks the goods either way man, well done

[Howley]

Yeah looks stiff as to me, but hey, I guarantee you know more about suspension than I do!

the line in red is the progressiveness.

Looks nice, thanks for the info.

[truckinduc]

ya guys its still a little stiff. When the bike is closer to finished ill re spring it both front and rear.

DONE!  finally up to date on this thread. I am a fabricator in SoCal and you need to move out here bro, You could run this place with the right connections. You would be like the Ducati/real bikes version of Jessie James. lol Keep it up, you a member of the Ducati Community?

[truckinduc]

What is the ducati community?  So I guess thats a no.

[Skyshadow]

It's a community/forum that is a phone app created by Ducati. Pretty cool, you see the big wigs on there and find out new things to do with Ducati very quick.

[NAKID]

Damn it! I caught up.....
