In the redneck dictionary, mass relates to size, as in massive.

At least you figured out what I was trying to say. I ain't the most educated old roughneck fer sure...

the only way you can change the weight without increasing the mass is to change the gravity of the planet

The height of the center of mass has a strong effect. When a top heavy bike tips in the wind, that is an effort to correct. On my bike the weight is so low that when it is hit hard it bobs like one of those punch 'em clowns. Despite the small wheels the corrections are effortless. The low mass is ballast and it is a lighthearted experience.

It varies wildly bike to bike, long trail, shallow raked bikes skate around less in the wind then short/steep bikes.

I used to live in New Mexico where the winds were +40mph straightline for weeks at a time in the afternoon, its a learned art. My Speed Triple has a steeper head angle then a lot of GSXRs, it really gets kicked around, the trick is getting low over the tank and just staying loose and fast, more fast, more stable, My ex's sportster was pretty easy in the wind, for all I hated the foreward controls, her Ultra has a fucking wrestling match, that head mounted bat-wing made dealing with heavy wind a fucking wrestling match with a near 900 pound bear.

My 675 is actually easier to ride in the wind considering its near 100 pound weight advantage, everything happens so fast on that thing that most wind is dealt with at on the pegs, there is little actual steering input required.

I own many bikes, including a ZN1300 Kawasaki Voyager 6 cylinder. The Voyager is the one most susceptible to side winds - scarily so - even though it weighs 1,000 pound unloaded.

So no, more weight most definitely does not imply less susceptibility to side gusts. I think the key ingredient is side surface area. The Voyager has a massive fairing, panniers and top box - in the manual it even states that you will have more problems in wind than a regular bike.

It's an aerodynamic issue more than a weight issue, with the wind.

Some of the heaviest bikes I've ridden have been the worst performers in windy/gusty conditions.

I suspect its a aerodynamic issue, especially an issue with the winds affect on the rider, who makes unconcious steering inputs. Tensing your arms in the wind may be the problem.

I had an Electra glide and the wind hardly affected that thing. Of course twisting the throttle hardly affected it either.

I doubt weight is the main issue in the wind.
I never had a tall bike with lots of plastic/radiators/windshields on it, and have never been bothered by any wind.

Smaller bikes with a low center of gravity like old bikes did well, as does my TU250, a 320 pound standard bike.
It does a lot better then most other bikes I have had, even though its light.

Riding old Triumphs, Harleys, all around the US, I cant remember any time wind was a worry.

I imagine a tall water cooled dual sport would be exciting!

Vstrom DL1000....... 60mph gusts put me in.... the on coming lane of traffic. Rode down the road on the side of the tire to move straight in my lane.

I think less of the weight had a factor, height of the bike and amount of side mass the wind could hit.

My buddy on his FZ1 right behind me said he had less of an issue.

Exactly, for example my old KTM950 was a handfull in quartering crosswinds. My Yamaha WR250, not so much. Some of you may recall flooding in Nashville a few years ago. I was riding to Scottsdale and made it out of town in a nick. But the incredible crosswinds blasted me all the way to El Paso. I got pretty loose on the bike, and yes, it took the most forceful counter steering I ever experienced to stay on the road... It was a brutal trip.

I've had similar winds on the Northern Plains through the Dakotas. I'd say the aero character of the motorcycle is more important than weight. Just look at a KTM 950/990 and imagine a quartering crossblast pushing all that gas tank surface and fairing.

My XT350 didn't have much trouble with gustry crosswind when I was moving.

I always figured that was because the raised front fender had enough side area and leverage that the wind would cause the bike to countersteer itself. It was kind of fun to ride in the wind for a little while.

That's because you were burning E10. If you were using pure gas, it would have been fine. (Joke, joke.)

Does bike weight affect stability in wind?

As others have suggested, it does a bit, but it is not the whole story.

I would not suggest buying a bigger, heavier bike in order to be more stable in the wind.

Taking on board some of the suggestions in this thread, and learning to deal with wind would be a better idea.
