As some of you know I bought my son a 00' XR100 for his first bike. My son is ten years old and can only reach the ground on his very tippy toes while sitting on the bike. I thought this was a good size for him since kids grow so fast. Pluss I wanted to get him use to a "real" clutch at the very begining.
The first time I took him out was in the desert in the sand. I figured if he can ride deep sand he can ride anything, pluss there is nothing to hit out there

He learned how to let the clutch out, the feel of the bike in first gear, how to bail / lay it over, front brake, and rear brake. He can't start the bike at all. He is a little small to do it. So the first day was me running after him just learning 1st gear and stopping. He did pretty well....
The second time I took him back out to the desert. I wanted him to learn how to change gears and get a tad bit faster. He needed to be faster because of the sand. I took him to a wide open area the size of three football fields put together to learn to change gears. I ran with him as he learned to change gears, he was doing okay......

The he started to go faster, once he did this he started to get a lot better. I jumped on my bike and we rode circles in that field for a couple of hours. He would down shift into second in the corners, put his foot out, complete the corner and change gears to third in the straight away. He did real well.
This past Saturday I took him back to the dunes to ride trails. We got there early and no one was around so it was great timing. We rode up and down the main road a few times to get him use to the bike again. Then we found a 2 mile trail that does a cicrle. We would start at the truck and end at the truck. The trail is all sand with a lot of whoops. We went pretty slow the first time around. He dumped it a few times getting use to the way the bike handled. Then he started to go a little faster (3rd gear) he was doing much better!

He was standing, head was up, elbows were up, he looked like he has been doing this for a long time

He was going over the whoops with his butt over the rear fender, then thowing his body into a sitting position in the corners. He was doing real well. Then I decided to let him lead while I watched from behind.... That is where I made my mistake

He started to go faster and faster, his little 100 was up in the air and out of control! He was doing pretty well until he went around a corner, the whoop threw his bike sideways, when he hit the other whoop it was all over!!! He went over the bars head first and into the sand!!! Once I got off my bike he was still laying there not moving. He was out!

He woke up and then started to scream!!!! He wasn't really hurt but very scared! He didn't know what happened to him. His mouth was full of sand, and his nose was plugged with sand. He started to cry a little bit then he saw his bike........ He started to whale like a 2 year old!!!!! His bars were bent, and the hand guard was broken. I think he was more upset that his bike wasn't all new and pretty looking then anything else. I told him not to worry about it, now it's time to get some better bars. He got back on the bike and was off over those whoops again.
I'm proud of him being this is his third time on a bike and all. But I'm also scared that he will get hurt. I'm just glad mom wasn't around!!!!!

We got back to the truck, sat there for a second, then he looks at me and asks where there might be a jump that he can try.....

I looked at him and said, let's load up and save that for next time.
Sorry for the long post, I just wanted to share my story....
