Looks like he's a fantastic rider and he appears to be doing this in a safe location, but why would someone risk crashing their bike? I work too hard for my toys. I would never try that stuff. But I'll be glad to watch someone else destroy their bike.
No Concern here sorry. Im in no way learning to wheelie. That with this machine would be consequential and yes you may damage your sexi beast. I however learned long ago on past bikes, so there is no real danger. Just my situation and opinion and the reason I posted the link in the first place. If your scared...... Go to Church. Joke!! Have fun and be safe.
