Thanks for the info!
I have just mated my EA81 with the RX-gearbox.
Now Im taking it apart to place restrictions on gear 4 & 5.
I will only be using the lower part of the Leone susp for the Brat.
(I'm running a complete EA82 front suspension under my BRAT).
This got my attention!
What did you modiify in order to make this work?
Do the frame fit bolt on?
