A guy at the gym had just bought a fat tire chopper. 280 rear tire. On the second day he was on a curvy road less than 30mph when "a car was hugging or crossed the yellow line" his version is the fat rear tire caused the bike to turn to quickly and he ran off the road.... over a guard rail....

I've never riden a fat tire chopper. And I don't believe his story. My guess is he just didn't know how to ride and used turn the bars instead of leaning..

But how easy does a big fat tire chopper flick into a corner?

Not Easy, they don't turn fast at all....it's all about the lean. Depending on how far the bars were raked, it does very little for usable steering control. The fat tires are much slower to lean as well.

Ryker,
The fatter the tire the slower the steering, you can try this experiment on any bike. Just go up a couple sizes in rear tire width and you'll how much lazier the rear end feels. Looks turn heads, not bikes : )

Choppers in general don't steer for crap. Anyways most people who crash during extreme steering wash the front end, I can't think of anyone who willing chooses to ride into a fixed object (like a guard rail)

They dont flick at all, kinda roll. Had a 300mm on the rear of my gixxer and sold everything to get the stock setup back. Straight line guys love em. I dont.

They're great in a straight line, lots of traction.

It's all about the angle of the dangle

My guess is the "chooper" rider entered the curve and got scared. Either froze up or just turned the bars.

I knew it was BS - blaming the tire. But he is OK just some bruises and some pride.

He could have bought 2 Buells that are rideable for the 20k he paid to look cool.

Exactly where traction doesn't matter.

Fat tires, chrome, buttless chaps and leather bar-end tassels - all contribute equally to vehicle performance.

Exactly - and that's where traction doesn't matter - sitting dead upright...

On some of the big cruisers you have to ride around the back tyre.

M109E Suzuki - from a stop, you have to get it pointed in the right direction BEFORE you nail it. It's ANTI flickable. All right when it's going, but from slow speed - queen mary.

In the riders defence I wouldn't discount a custom cruiser doing something entirely unpredictable in an emergency situation though.

He's just got the symptoms wrong.

Guys the experience he had is due to the sudden transitions the extra wide tire goes thru as you bring it up on its "sidewall". There is an initial resistance to "flick" followed by a "holy shit where did that come from" transition that if you are not expecting it can and will kill you. Usually hard parts are also draggin by this time so there are a multitude of "steering inputs" happening all at once. Sort of like the question of how much distance does it take a train to stop, lay it on its side and it can stop pretty damn quick.

My guess is that he never explored his bikes cornering limits and no one warned him of the consequences of cornering with that huge tire. Choppers are unusual in that the bikes cornering limits are well within the skill set of even unskilled riders. There is natural tendency to "believe" that it ought to corner faster, leading to surprise when it doesn't.

Most of us prefer the other situation where we run comfortably within our limits secure in the knowledge that if we really had to turn harder the bike could.

Since he was at speeds less than 35mph. My guess is he "turned" the handle bars too much - either on purpose or due to the poor design and his lack of knowledge on that bike.


Another reason why I don't let guys ride my bike unless they own/ride the same type of bike.

You didn't know choppers were flickable?
Damn, You probably didn't know they make awesome off-road bikes too.

A wide tire chopper Flickable? Like a booger!

(Feels good when you first get it out, but tough to get off your hands later)
