To much lean angle is right about at the same time you fall .
HAHA. You've nailed it on the head, Fajita Dave (I want Mexican food every time you're on the site).
How comfortable you are leaning off the bike, Apanna, plays a big part. I'm having problems because I can't quick turn the bike or get it into a corner with enough speed, so I can't really get it to go all the way over. It's also the setup. I have stock everything on my bike, so I occasionally scrape the peg, but the bike can do so much more.
Other than that, if you have the right tires you can get off the bike and lean until you scrape hard parts.
And are you saying this forum is boring, Appanna?
