Hello Vince, in the local club I ride with we’ve got a number of youth riding various EMs successfully from 11 or 12 years old. All for fun though, no sanctioned competition.
I’m aware of one family who attempted youth competition on electric and really struggled to get the bike understood, plus complaints it was unfair as clutch control not necessarily required, cannot stall etc. To the extent they sold the electric and went back to a gas bike to cut the politics and just get riding.
Admire your DF and it’s lightweight. Would love to compare one to my EM.
