Thanks Max
Swingarm will be fairly conventional box section, I machined up pivots and mount bosses yesterday but the piece of 20mm bright bar I had for pivot shaft has turned up missing
so no tacking that up till Monday.
The swinarm pivot shaft will run the full width of the bike with an extra pair of bosses that will be gusseted from the midrail all the way down to the bottom rail to try and spread the load and push on the strongest parts of the frame. You can see both rails in the rear engine mount pic.
I'm trying to do something a little different with the front wheel action (+ I don't have the skills to make a hub centre steering), I think I have it working but no pics until it's made out of something better than scrap bits of wood, curtain rod and techscrews.
I'm planning room for a turbo and intercooler for the Busa motor, anything between the motor and fire bottles will be able to find a new bit of realestate if needs.
I hope to drive up, I won't be making near the torque you are but a 6 speed box will help, I'm a bit winky on getting towed.
Yes, same size front and rear tyres, the wheel will bolt up from different sides front and rear so a single spare can be driving or driven and get the rotational direction right.
Thanks
