Scraping Pegs

[iwannadie]

it still amazes me to see pics of those guys dragging a knee, the bike looks like it should fall right over. it shouldnt be able to hold its self up like that lol

I don't think "scaping the pegs" should be a priority for the newb however.....

Early on, no, but once the basics are mastered it wouldn't hurt to practice low-speed peg scraping during tight circle maneuvers in a parking lot. If you get used to the aggressive angles and know what the hard parts sound like when hitting pavement you'll be less likely to freak out in the event an evasive maneuver becomes necessary later on when you're out on the road and more likely to act appropriately.

I knew a guy who claimed that you don't fall over because you are falling forward....of course he never rode a bike through a turn leaned waaay over and hit a gravel patch/oil/roadkill.

if you had a bike on a dyno type setup with the engine revved and the tires spinning could you lean the bike in theory?

i read that f1 cars have enough downforce they could drive upside down and stick to the road without falling off. love to see that done some how ha.

Interesting question...

While the wheels would be spinning (assuming you're suggesting that the dyno would artificially spin the front wheel) thus acting as gyroscopes, the sprung weight of the bike would NOT be moving and therefore would not be contributing it's own momentum to the equation. So, essentially what you're asking is if the gyroscopic forces from the wheels would be sufficient to hold the bike in a "static turn" to which I would have to reply with a resounding "no".

be cool to see someone try that too though even if its sure to fail ha.

again it amazes me how a bike can lean, i was pushing my kat and went to lean it and had to use all my strength to keep it from falling. but sit on it go not even 10mph and it will lean nearly scrapping pegs without a problem. guess that little foreward momentum makes a big deal.

The downforce would hold the cars to a track "upside down".... I have seen people ride on bicycle treadmills without falling over, but I don't know about the cornering/leaning thing though.

Yeah, it's that forward momentum that translates into downforce when taking a turn. Add to it the rotating mass of the wheels and tires for lateral stability and...well...it's just physics.

MMMMmmmmm.....physics.

Well...for those of us who like that kinda stuff...or are turned-on by it like Joe here.
