how much detail do you want? steve at luckyseven is in the process of making these frame brace kits like fitted to this frame and selling them on to owners, you just need to weld them to your frame. might be worth contacting him before you start.

This is the traditional drawing, but I added a couple of extra tubes at G (Works better on the early frames that don't have the big engine mount brackets like in the picture). Also, I ran the tubes at A towards the fairing side mounts instead of into the middle of the yellow tube.

In this context it might be interesting what the professional racers do.

Here's a pic of Steve Martin's Kat frame he uses in the Aussie Classic race series. Completely new fabrication, still instructional.

With respect to the lunacy that S Martin et al are involved in, you can get away with a little less.

Again new build and about 30HP less than the Phillip Island bikes, but more than capable of seeing off most things of the generation.

Liking the Luckyseven work though, well thought out.

A most interesting thread this one, i am currently gathering parts to build a 7/11 Kat . Just added some more nice parts to the heap today ;) Looking around on the net the amount and placing of some of the bracing seems universal. Other chassis areas more regional, fashion perhaps xD   

johnr question for you sir,  in your photo the underseat tray you have made how deep is that and is it hidden from side view with the seat in place.

Katmangler your frame side brace is that just a flat plate or boxed like johnr`s ? 

Pedda do we have link to that race bike ?

 

Thanks

Mine is a flat plate not boxed. If you hang on until the end of the year. Our GSX frame bracing Guru Stragewayz should hopefully have completed a detailed how to for us. ( he did the Lucky 7 frame too)

The undertray in JohnR's picture is a Lucky7 prefab too they come in two parts.
