I can get the front end up there but I'm not too good and "riding" them out on the max.
I used to be pretty good with em on my CR5. I would get it up in 2nd and I could let it hang up there for a while, shift thru the gears and finally drop in down softly in 5th.
I am really out of practice though since I haven't been riding the CR much in the past how many years. I actually had a pretty good wreck over memorial day weekend trying to show off. I was going down a really poor dirt road. I went flying by my wife and sister in law riding a nice one in 4th gear. I was toying with the throttle keeping it in the sweet spot. All of a sudden I felt it go past the point of no return and I looped out! I landed on my feet but was going way too fast to be able to run with it. Fell down onto my ass and slid on the rocks for a second or so. That didn't feel too good so I pushed my hands down real hard to help pop myself back onto my feet. I was still moving pretty fast. My legs were having a really hard time moving fast enough to keep me from falling flat on my face. I was running so hard my arms were circling in a windmill like fashion. My bike had finished cartwheeling and I see it is lying directly in front of me. Did you ever try to jump a hurdle while running as hard as you can? Its pretty tough!
My wife about had a heart attack and said all she saw was me flip over backwards, then a huge cloud of dust, my bike cartwheeling out of a cloud of dust, then me wind-milling out of a cloud of dust, hurdle over the bike, and run off the road into the weeds. My brother in law was in front and turned around just in time to see the whole thing.
I was fine other than a tiny scratch on my ass and hand. My pants were torn apart though. And the bike needed a new set of bars since the left side was bent and nearly touching the radiator. I rode it like that thru a short loop in the woods and had to call it a day till I got new bars the next morning.
If you're going to practice riding wheelies, make sure your covering the rear brake and ready to use it! It is NOT a good feeling when you know you are going over backwards.
