I'm mid 40s, getting back into riding after 25 years away. I bought a WR450. I'm trail riding with it every week. I'm not racing. I'm riding. But I'm riding with guys my age who have aspiration of racing, mostly just for the fun of it, but speed is always on their agenda. I've never really been injured on a bike. And I don't want a serious injury. I've been reading the neck brace thread as well as other threads that detail injuries. I'm not seeking them out, there are just a lot of them. I'm amazed at how many people get hurt and how serious the injuries are. We were at a hare and hound race last weekend. I observed from trail side. Great fun to watch. But I couldn't help but notice the 16 year old rider not participating because he was wearing a neck brace due to breaking his neck while going over a log pile on his training course. And my buddy was back for the first time since getting lost off the trail and running into a fallen tree, giving him headaches for 4 months. And then there was the guy back from smashing his ankle last year. He was on crutches for 6 months. I love that I'm riding again, but I need to stay injury free.
