slack reactor

i have a slack reactor. from reading i am to understand they don't make a Jr kart??? i have an old ultra max that has been my usually ride. its spacious.
haven't spent much time in the reactor... first race was last night. i measured the foot box and its just barely enough room for both feet and they touch each other while i drive. not an issue with my ultramax. is this common on these kart to have no foot room... do they make a wider foot box?? the whole kart feels small..


Your correct Slack hasn’t made a JR kart, but with that being said, they have setup plenty of them for JR drivers.
Never had an Ultramax or ridden one, but all the slacks we have owned or ridden have had the same amount of foot room as any of our Phantoms.
