Truckers Monster Rebuild

[ducatiz]

Here is how Ducati did it on the Pantah:

Frame member right next to the belt cover: if the tube wasn't flattened, it would be about 2mm IN the belt cover.  (click thumbnails for full size)

thats pretty ingenious. i would never have thought to do that to the frame, for fear of compromising the the integrity of the tube its self. but if ducati engineers think that its ok then who am i to say differently

Hey thanks alot for the pictures.  It almost seems like a mistake or an afterthought though. Or the frame guys and engine guys didnt get together enough pre production.

Thats the simplest option and most likely what ill do, although it will only be a very small area compared to the pantah frame.

[truckinduc]

this reminds me of the frameless ducati roadbike. very very neat stuff.

Yep, its VERY similar to they way the d16rr and desmosedichi's (sp) rear suspension.  Honda did it first with the rc211v and then the 600rr and 1000rr.  It apparently upsets the chassis less while leaned over on a less than smooth surface.

I want to have the first monster with that style rear suspension. Its hard to be original these days.

That's a good question, and probably true. 

However, they had 12 years to figure it out -- that frame is from an Alazzurra, which is just a last-generation Pantah rebadged by Cagiva.  The frames on the first Pantah 500s are nearly identical.

I think they were trying to make the frame as thin as possible, which is a selling point of the L-twin layout.

i didn't know your suspension design was close to the frameless design. your frame work reminded of how the frame and engine are mounted. the frame being in 2 pieces and how the engine is holding everything together. amazingly simplifying the monster's design even more.

I can't quote from this blackberry but that seems very logical. I can't stand to ride inline 4's due to their width.

My frame is very similar to the ducati supermono frame, Although the rear suspension configuration is different.  In stock configuration the engine is a stressed member. In my version it also is, just in a different way. I'm joining the frame and swingarm pivot to eliminate a lot of unnecessary forces through the rear of the case since I'm removing so much material.

[Düb Lüv]

sorry truckin, i meant you're amazingly simplifying the monster's design even more. having the trellis swingarm cleans up the profile of the bike sooooo much. very nice and inspiring work.

[truckinduc]

In my opinion ducati's "frame-less" patent is anything but frame less.  I see a separate frame for the front suspension and a frame for the rear suspension, only they are not connected.

An actual fraimless bike to me is the v1000.

worked on the eccentrics more today







tomorrow they go on a diet.



Also got the motor jig complete for the front end.

[truckinduc]

finished the eccentrics today. they look good and are very light weight. too bad I cant use them. Oh well they will at least work for mockup and the swingarm jig. 3 days of work down the drain.

[TAftonomos]

And you can't use them because....

[truckinduc]

take a look at the pictures and see if you can figure out why I cannot use them.

hint, first pic.

ahhhh.. you instibated the circular confabulator and the modular kreason has too much heptalagular radius...

man.. sorry.
