I confused that pic with a setup of the FCR units on a japanese site
great stuff!

the only issue is the 56a box is so light and efficient that nothing
comes close for bang for buck for its little use of hp compared to
a box with bigger gears and internals.

Harder materials to replace the internals is super expensive although available
but I still wonder since we are only making less than 200hp if its possible to
use a Baker DD5 or similar aftermarket Harley box which are sequential and used
on drag bike with 50% more torque than a stock A15?
