I think your definition of subjective is subjective. Lol

Now I'm trolling.

And yes you can use the lean angle to relate to corner speed required to hold a given radius. But if all you're after is cornering g's that force is in balance with the weight of bike, so all that matters is the angle through the c.g..
My point with that is even though the lateral acceleration will be the same for a given lean angle it is not possible for all bikes to achieve the same lean angle. You say max lean angle, op says max lateral g's. Which will be different for each and every bike.

Did you achieve a 60 degree lean angle, yes or no? Did you see a place to inject your feelings emotions and opinions? If you didn't then achieving a lean angle is not subjective. Just because everyone can't do it doesn't make it subjective.

No but it is telling you to off

Lean angle is all that matters? Speed isn't a factor? Hmm

The speed and radius of the curve will determine your lean angle.

2014 Chevy Corvette Stingray Z51 = 1.08g

You're not going to get anywhere close to that on a production motorcycle

No prob, you have the correct and objective understanding

My point was its easier, and equivalent, to think about in terms of the lean angle even though g's will be easier to measure.

It is also interesting to see how nonlinear the effects are. As a few extra degrees past say 45 to 50 deg mean a lot more for cornering speed than the same amount at lesser lean angles.

But thinking about how bikes would differ, what limits max lean angle limits max g's. So I think it really just testing the rider (and the magazines insurance policy). What I'd expect from the results is to learn when the stock mounted postion of the pegs or muffler touch the ground.

Tell me again how grip/traction don't matter. I don't get it.

I was being a bit short on purpose but wanted to make the link to lean angle. I left it unspoken that the traction to support said lean angle was available. The reason because the g's is just the lean angle you can hold.

Intersted in your opinion. I know you the got the data. I'm sure it shows g's greater than those examples ( heck there's even a video in this thread that does). But like I said before anyone on a bicycle who leans over past 45 deg would beat those cars too.

What makes you think someone can lean more than 45 deg on a mountain bike for example?

Do you think you could go through a turn on your motorcycle faster than an average sedan could?

would braking in a turn affect the lateral g's?

Yup, but they stay off the brakes when they test cars for lateral g-force

Lateral = Side to side force correct?
If so would there even be any lateral g's if you corner correctly?
I could see if you high sided they may come into effect.

Imagine you have a motorcycle on a rope and you're able to swing it in a circle. If there were a monkey sitting in the saddle he would be experiencing g-force. The motorcycle being on the ground riding in a circle doesn't change that force

Yes I have lots of data. The video in the thread is from my bike and data acquisition.

You seem to have a lock on the physics behind lateral g's on a bike. I'm just doing some internet learning from you.
