- SELF INTRODUCTION: I like motorcycles and am interested in potentially building/heavily customizing one for myself. I am 40yrs old and have a wife and a bunch of kids. My first bike was when I was 12yrs old. It was a Suzuki RM100 1978 that I got for free from a neighbor. It had a crack in the case from a chain that broke. I spent the summer fixing it. My parents just smiled and brought me to the places I needed to go to get parts or have the case welded. They thought it would keep me out of trouble so they didn't ask a lot of questions and kept encouraging me. I finished the bike that Summer and kept it about 10 years before passing it on to another teen for free.
Frameless frame
Does anyone have any experience building a frameless frame, meaning the motor is a structural part of the frame with no down tubes other than to connect to the top of the engine? I am doing some reaserch on whether or not it would be feasible with an old goldwing engine, since it has 4 mounting points on each side, I was hoping to let that big timing cover hang out in the open without down tubes. Only found one example of an old kaw while searching, but not much info on it.

I started a project build there " File and Fit." I paln to continue that when I go back home in Dec. 2011. I first joined the board when Gary W had it in the year 2005. That was the time I really gained an interest in building chops. I have a long way to go, compared to some here.

Re: Frameless frame
I am impressed you found one. Not as simple or elegant as I would hope to do it, but it does lend a bit of credibility to the idea. Thanks for the reply.

Re: Frameless frame
You could easily "recreate/reverse engineer " this in a early Buell or Ducati style frame, using small diameter tubing .mike_mn wrote: but it does lend a bit of credibility to the idea. Thanks for the reply.
I originally saw this image online 15 years ago. I have liked it ever since.

Re: Frameless frame
Do a little research on the Vincent motorcycle ! Remove the engine/trans and all that is left is a small pile of parts that constitute the "frame" !!

Re: Frameless frame
Keep in mind that frames like this are designed around powerplants that have also been designed to become a structural element. Not all motor/tranny assemblies will qualify or be up to the task of handling the stress of becoming part of the frame.

Re: Frameless frame
Good advice, I did not think of that. The castings may not be strong enough in the mount areas.gww25 wrote:Keep in mind that frames like this are designed around powerplants that have also been designed to become a structural element.

Re: Frameless frame
Use multiple mount areas , create struts between two points that you think need to share the load , THINK and do your research and ask as many questions as you have to !
That's what we are here for !

Re: Frameless frame
Hello,
Don't know if it's of any help but a British guy called Twizzle built a frameless Triumph some years back. He used the exhaust as a stressed member. If you google Twizzle custom bikes you should be able to find him

Re: Frameless frame
I certainly wouldn't tie to the heads like Vincent did on an engine without cylinder studs that went all the way from case to the head.
But with a little thought n where to attach I would think most engines would work for a frame member.

Re: Frameless frame
If this is yours, do you have more details or build pics?

Re: Frameless frame
Not mine I grabbed the pic off the net to illustrate how Vincent did it. I did get to ride a Black Shadow a few years ago, it was amazing! It handled way better than the magazines said.

Here are some of Twizzle's frames of this type.
He uses only stress member sport bike engines designed for it in the castings. My Busted Rubber bike was inspired by his frames.
