Thanks for the comments all!

Rusty McNeil, nice looking DIY brace & posts. MidnightMax, thanks for sending me the pics of yours... Awesome bracing work! I like the "X" brace towards the pivot area. I'll post it below, plus an interesting one I came across in another enthusiast's site... very slick "stock" approach which would retain the OEM exhaust and center stand.

Also, what's the verdict on inserting and welding in a ~3.5"in OD pipe section in the driveshaft entry point? Midnight Max did so, and it's been mentioned in the old tech-mailing list archives. Does it help?

Cheers all.

Lugan - my pleasure and next time I'll try harder to get the focus correct!

For inf, the centre stand still fits with the arrangement I have.
I can't comment on the OE system as I've never had one fitted but it does work OK with Holeshot headers.

Thanks for all the good posts and info gents. Any more images, please post them up!

FWIW, I got started on cutting and shaping some 1inch OD 16ga mild steel tubing for my swingarm. I also cut and bent a piece of 16ga plate steel to reinforce the 'box' area of the swingarm, but still allow clearance to the gas tank drain bolt etc.

I have to cut some more tubing pieces to tie it all in together, but so far my design approach is to reinforce the arms to the pivot/bearing areas, and add in a brace between the sides to reinforce it. I also opted for thinner tubing to keep weight down. Availability and ease of bending with a conduit bender factored in as well!

Here is what we did. I like the old ladder bar setup
