I am back into riding after 15 years. My 10 year old has gotten the bug for motocross and rides a CR85. In my younger days (alot younger) of racing, big jumps then now are being doubled and tripled. Just amazing. I am now riding a CR250. My question is how do you practice and learn how to double these things without the painful learning curve and experiencing serious crashes? I have read that you should practice on table tops. I feel pretty good with those but the approach/ramps are so much different. Not that I don't have the b_lls, but who wants to charge into something knowing that a crash is waiting for you at the other end..Thanks for any advice.
