Triton Jr kart new for 2014

What kind of pedal set up do they have?
Is the mastercylinder part of break pedal ?

It already has places for the pedals to be moved up for the Jr's now. Don't quote me, but I'm pretty sure they're testing different frame stiffness parts to fine tune the chassis for lil ones. This is just my assumption since the chassis is already a beast as it sits now.
