Either for his birthday or Xmas next year we'll get him a CRF50, (with his mums permission of course )
Than as he grows older i can keep modding it to suit him, than by the time he's 10 he'll have a CRF50 thats pretty pimped with 108cc kit, Protapers, HD clutch
we ride around on the ST50 all the time, he sits up front and can control the throttle and change the 3 speed auto gearbox up and down when i tell him to change gears of course,
just gotta be careful though cause he thinks its hilarious to change gears whilst still having 1/2 throttle on, than cracks up laughing when we are popping wheelies
