that bumper will be illegal for racing.
so did you or someone else just rattle can the frame?
Agreed, brakes should be at the top of your listand get some rear brakes on that thing
i got the idea from that kit yes, but i work in a fabrication shop so im changing it a bit so it will def be stronger n no problem for a mx track. also thinking about a longer swingarm, any thoughts on what a good lenth is?
