I have an 8 year old son about a year ago I got him a xr50 and started taking to a freinds house with a big flat yard in the back started slow and worked his way up over the past year so about 3 weeks ago took to some wide open trails that his freinds ride on he had one crash and wanted to go home I told him to just take a break and give it another try he he rode a little longer and we went home now he will not go and just wants to ride in yard where he started then last nite he told he will ride anymore just to sell his bike thanks for any input or help.
