There's not need to instruct Brent on the fine art of wheelies. He's a little banged up right now. Maybe two wheels on the ground is the best way to go?
I partly disagree. We all know the front wheel will come up frequently after about 3 days of riding and learning how to handle a bike. A wr450 is not a toy. Heck it even happens when one learns to ride a bicycle. One needs to learn how to react when it happens.
Its kinda like driving in snow......if you never deliberately spin your tires or hit the brakes and feel the effect you won't know how to react when it does happen.
Just as you guys say, he should have hit the gas when seeing the drop-off. This may seem contrary to what a new rider thinks but it works.
Anyway I hope you heal up fast Brent and get back in the saddle soon.
