Ben building a lakester in the basement for more years than I want to admit. You should hear the grief I get about grinding down there.

The rear half as it stands is similar in construction to a lengthened Hayabusa swingarm with the brace on the top instead of the bottom. I know that a good turbo 'Busa makes 630 horsepower and they handle that without any obvious problem.  I plan on adding some diagonial tubes to stiffen it up. I think that this chassis will successfully handle the 160 horsepower a ZX10 makes. Back in the mid 70-s I drag raced the twin to this as a funny bike. Z1 Kawasaki -1000cc turbo, alcohol fuel. Pre dyno days but I would estimate it made about 170 HP at 14 lbs boost. Ran 9.0-s at  160 mph. The Chapman drag frame I use with the 1350cc H-D engine handles 130 horsepower and has gone 150 mph without any issue at Maxton, Loring and Bonneville. I think that a ZX10 engine could push an open bike to 170 or there abouts.  No concerns once I verify geometry on my chassis jig.

I am considering some triangulation adds ... the geometry looks right as the axle is directly inline with the swingarm pivot. This is the strong part of the frame

Out of the blue another frame turned up ... this one is a lot beefier in the back half ....  Oh well, what is one more frame?  Might just have to build another bike ...

A little tough to see but it is 40 degrees ...


Frame option 2


This one shows an angle of 45 degrees ...
I prefer 35 degrees ... guess I can take some rake out ... both of these frames are Z-1 type frames from the 70-s that were back halved.  the purple on is way over built ... the raw steel one needs some bracing ... I have another drag frame plus a stock frame with a Kosman "big foot" swing arm on it ...

Better build up all three to test the various rake!

I'm just noticing the evolution from the dining room table to the patio table to the grass!  shocked

Were you standing on the dog house or in the doorway when you took these pix?  huh

I prefer the third 1.
plenty of fuel tank volume , a lot of bracing and a great ( for me ) and stable rake.
