YOu Repro boys build one of these babys... Moto F is so last years
« on: November 18, 2011, 02:10:55 pm »

What constitutes a "works" bike? How about a prototype water cooled YZ125 in an era of air cooled production machines... Trick!

I assume that size to be for the upper triangulated part, the lower main extrusions look square.
And is that the size of the production tubes or the size of the works tubes?

Tubing needs to be 6061

All the box sections should be that size and with rounded corners.

And yes 6000 series. Now you see my dilemma? Although I only have one choice,,,
