Weight is a small factor. Inherent stability of a bike is dependent on a lot of factors. Aerodynamics, rake and trail, height, side loading, etc.

BUT, in my experience, the rider can make a huge difference. Don't stiff-arm the handlebars. let the bike move a little and keep it loose. As also noted, direction of the wind matters, but poking a knee out in the direction the wind is coming from can be very effective.

There are only a few things that dictate the effect of wind on a moto according to the wise sages.

1. Whether you are running a car tire or not? (Dark Siding)
2. What type of oil you use?
3. If you are not ATGATT you WILL die.
4. How many fingers you use on the front brake.

Happy to Help!

Did you read the other posts?

Plenty of people have given examples of bikes that are light and no issues in windy conditions. Weight is just ONE factor, certainly not the only.

IMHO the way a bike is ridden is at least as much a factor. The way it cuts the wind, aerodynamics and side loading (height) all play important roles.

Example. My lightweight sports car has zero issues with wind, but my much heavier SUV is all over the place.

First of all your contribution made me

SUV / Porsche
FJR1300 / Ninja 250

One is heavy one is not, one is small one is big, one moves slower than the other, one moves faster. etc..etc..apples to oranges you say?

Privilege us with more of your knowledge?

That being said--my 08 Streetbob gets buffeted around way more then my 1200S, but only slightly more then my KZ1000, The 1200S weighs less then both of these bikes and the KZ is damn near 600 Pounds and the FXDB is 667--If that's the MAIN issue... then I think the laws of physics don't apply to me, I think it's more of a Aerodynamic issue then a Weight issue, as pointed out many times all ready.

No doubt aerodynamics plays a part.

But weight is a big or bigger a factor, unless your riding you bike down the road under sail power.

My RZ350 is almost impossible to keep between the lanes on the same day that my Ultra, weighing 3 times as much yet also presenting a much bigger profile, is a rock.

You don't believe weight plays a part.
I'm gonna make this real simple for you.
Lay a piece of paper in your driveway next to the hard cover book you tear it out of. Single piece of paper, much lighter and less profile than the book.
Which one do you think you're going to have to chase?

How the hell can a thinking human being not believe weight plays a part?

RAYO . You keep thinking of aerodynamics from a frontal standpoint. Everybody is talking about crosswinds here. Pay attention. Your Haybus was only aerodynamic from the front.

lol
So you believe two bikes with the same profile (side and front), one let's say 100 pounds heavier than the other, on a windy day, will both handle the same?

Try to follow the bouncing ball here junior.

I think we can all agree on that, but don't simply dismiss weight.

You can't have it both ways!

No , Windbag , I don't , but aerodynamics has MORE to do with it than weight. MOST of us here won't live long enough to be able to explain it until you understand.

I guess it's always his way. He wins no matter what.

There are two main issues with the database, sir.

Just admit you might be wrong FFS, act like a man instead of all this nonsense.

THAT makes you a troll, or an idiot, you choose!
