GS1000 Frame Bracing Templates?

[Fjbj40]

If I had an extra $1K, that is what I would do. Strip the frame, get it braced and then powdercoated. I don't have bracing on my GS with 18" radials, GSXR 41mm RSU forks/brace and a bandit swing arm and it is pretty stable but in hard cornering at say 80-90 mph it gets a little unsettling but nothing dramatic. In a straight line no issues.

The frame bracing cost me about $200.00. I cut and fit and tack welded the tubing. Took it to a tig welder for finishing and I then painted it with International Perfection poly urethane paint along with the wheels at the same time. If I choose to powder coat then it would have been $500.00 more. I have a down draft paint booth where I teach so painting is the most intelligent option.

Looks good.

Was test fitting of your tank required when you did "c" ?

Yes, I know, I ask a lot of questions....

Only after I had it welded in, then a few light blows with a hammer and it fit just perfectly

There is a picture in my build that shows this minor clearance.

Hmm... that's close - has anyone considered using a piece of flat plate instead. This would eliminate any clearance issues.

Also, the rectangular tubing you used Fjb looks wider than 1" - correct?

[Fjbj40]

Yes, I started with a piece 3" wide x 1". But finished it is only about 2" at its max width.

[philosopheriam]

I was thinking of using a piece of rectangular tubing that was .75 on the short side and 1.5 on the tall side with a .120 wall thickness... This would allow the brace to sit "below" the outside of the tube.

I had my 750 frame braced, probably not strictly necessary...





Some things to be aware of:

1. Access to mount coils was very limited due to A. I needed longer bolts and spacers to make them fit.

2. Airbox mounting tabs need removing to fit C. I used channel section for the bracing, if you use 3mm flat steel plate you might be able to retain the airbox mounts

3. Make sure you leave the swing arm fitted before welding D

4. D does not interfere with the airbox, but it does interfere with the battery box. I modified the battery box by cutting a 30mm section out of it and welding the base back on. This raises the battery by 30mm but there is plenty of room under the seat if you move the toolkit somewhere else, seat hump maybe?

Does your tank fit without hitting the edges of "C" ?

Cut your wall thickness in half, this is a motorcycle not industrial equipment.

I would be inclined to agree... most of the strength comes from the diameter or section of the tube not from the wall thickness.

In fact it might just be an optical illusion but I keep seeing a hardening stress riser at the top of the "C" mod. A little flex is actually in order.

In my mind it is pretty irrelevant as Tone already described the mods and what section of steel he used.

[Fjbj40]

I used his recommendations, Tone that is, when I was researching the mods before I did them. He laid out quite a few details and tips for the frame.

Rare and unusual; using "common sense"
