Perfectly explained video. I read these comments saying it's confusing or you aren't doing a great job of it and it blows my mind how they are getting confused. This was very simply put. Somehow they need a more dumbed down version.
Center of a "corner" is not called apex. It's called the focal point, which is the convergence of your radial lines of your cornering curve. The apex is where you end your entry and start the process of exiting the corner.
Please, look up the difference between centripetal and centrifugal. Your physics are all screwed up but you did a great job trying to explain what you thought you knew. In short you made a great video, just brush up on your physics.
I've never studied physics, I should have consulted with someone who understood this stuff more before I made this video. I would like to remake this video in the future. If you're interested, maybe we can write the script together?
I have read and watched much instruction...I am getting tyed up with correct gearing..not in the power band of the correct gear alot. Remedys or drills to improve? im over or under downshifting.. Rev match to slow down what rpm keeps you wound up out of exits.? The good riders start to slowly pull away I can hear their higher rpm and see them out corner exiting me. Course im 600cc they are all 1000. But i still feel disconected with my bike because correct gearing for the turn. Over rev over spinning tire... power rear tire slides out lowside.. under rpm lugs with no max acceleration. Nred some drills..thanks good video
sorry dude, but your first statement (and therefor most of your video) is wrong from a physics standpoint. First, lets break your physics into 2 stages, the 2D side of going around a corner, then why you have to lean. Centripetal force is always pointing towards the center of the circle, and is not an outward force as you describe. You can see the way the arrow points on the 2 animations included in your video. Think about it this way, if you were able to suddenly bring your bike to a complete stop while leaned over, you would fall to the middle and not the outside. The blue arrow in your video is inertia. This is the your bike trying to break free and travel in a straight line like all things try to do (newtons first law). As long as your centripetal force is greater than your inertia, you will go around in a circle. If your inertia is bigger than your centripetal force, then your bike tries to go in a straight line and you run wide. Now with bikes, you have the friction of the tyres to consider. This frictional force acts both downwards with gravity and towards the center of the circle once your inertia starts to get too large. This covers the 2D aspect, now on to leaning. When you turn on a bike, your bike pivots on its tyres against the road. The angle between the road and the side of the tyre is your lean angle. If you try to corner without leaning, your bike will start to turn, but you will keep trying to go in a straight line. This results in you falling off the bike. When you lean the bike, the inertia pushes you into the bike and pushes the bike into the road (because gravity is pointing downwards and the bike is trying to fight the centripetal force pointing inwards). Lean too much, or go too fast, then you overcome the friction of your tyres and the centripetal force keeping you turning, so your bike will try to go straight. This is your low-side crash. If a rider is able to slow the bike down, it is possible to recover from the bike sliding, but often the tyres come off the ground as you slide on your pegs. I hope this explaination makes sense (its a lot easier with pictures)
Great video! Is there a minimum cornering speed needed to remain upright (ie not lowside or lose grip) when leaning the bike really over (eg 50 degrees)? Otherwise, I’m guessing I would just fall over because the downward force (gravity) is greater than the upward centripetal force - assuming my cornering speed is too low.
Jrstrdr I'm sure there is, but all that would be dependent on a lot of factors such as weight and bike geometry. But you can get a lot of lean angle with very low speeds, so I've seen in some RUclips videos.
Yes, there is a minimum speed required and its all to do with "moments" (thats a physics term). Put in simplest terms, gravity is trying to pull you to the road, your mass and speed are trying to flip your bike in the other direction. Go too slow, and gravity wins and you drop the bike on its side. Go too fast and you start to slide outwards from the corner which also results in you dropping the bike and sliding. All forces must balance in the end.
Great vid. Still not sure I understand...? Question....how do you know when you've reached the edge of tyre?...when its too late.!!! I usually get to within 3 or 4mm of the edge but don't feel as low as you (very impressive riding and lean angle)
Comfy Sofa that's a good question, as long as you take it easy and build up your pace slowly you will develop a feel for the bike and sense when the front tire starts to push. But as long as you're I guess track day spec tires the front shouldn't just give out without a warning.
Thanks - i would say the question is more directed toward the rear as the front progressively curves over where as the rear has a "definite end point"....ie the end of the side of the tyre...
Comfy Sofa I would say both tires have similar end points as you call them. Too much front brake mid corner will take you that end point faster as it compresses and deforms the tire. It's somewhat true for the rear as well, but that deformation isn't caused by the brake but rather the throttle. It should still give you warnings non the less before it gives.
I would say we learn by falling. How does a baby learn to walk? The baby gets up and tries to balance and falls and this goes on and on while the brain says we have to correct this and changes are made ever so slowly until the child goes to running and falling and so forth. The problem with this on a motorcycle is it damages both the rider and the cycle. But, every time you fall you learn something and next time you make a little adjustment until either you are on crutches the rest of your life or you finally get the hang of it.
Centripetal force acts TOWARDS the center of a turn. Centrifugal force acts AWAY from the center of a turn. Grade school science students should know the spelling and the differences between these two forces.
I really appreciate the video bro but it was confusing af haha. Maybe a video with the go pro on a first person view doing the actual lean would be helpful
Sorry Fonzy...but you’re not equipped educationally to discuss forces. Centrifugal “force” is a fictional force that derives from centripetal acceleration towards the centre of the curve as defined by the circular arc you are in the corner. Clearly you know how to ride a bike- and that’s what counts- but please don’t try to put your “professor hat on”. Not workin’....but nice try. Your intention is great....
Centripetal is towards inwards of circle
Centripetal force is inwards the center while the fictional outward force you are referring to is called centrifugal.

Thanks dude! I stopped reading the comments because I want to reply to every single one with "Yo Mama".
Yellow ball you mean or am I colorblind?

Positivity at its best,subscribed!
It's Centrifugal force not Centripetal. But still, good, explanatory demonstration.

whats the right thing centrifugal or centripetal?
@@oohbleeblooblaghblagh9211 centripetal force is always towards the turn. Centrifugal force acts outwards of the turn
Thank you! Great explanation!
Omg, i actually understand 🤯
Force on outward direction called centrifugal force
1:30 so how much is the suspension effected working at angles add opposed to more uptight riding.?
Hey but why we have to lean the opposite direction of a turn when we're making figure 8
You're going way slower so this video doesn't apply to a figure 8
Great video!

2:50 look how an small those contact patches are wow
hai dude...how much capacity of oil in the front fork?? is standar factory or you adding of oil?? how much?? i'm ninja 250 user from indonesia....
Good explanation.
Is it ok if I hold my weight with the gas tank and my outside knee?
Yeah, it's ok. We have to hold our weight on the gas tank using our tight grip of knee and thigh.
Centripetal force acts TOWARDS the center of a turn. Centrifugal force acts AWAY from the center of a turn. Grade school science students should know the spelling and the differences between these two forces.
Dude! Thank you!!!
None of this is correct, I get where you're coming from but the physics isn't really there... Sorry man
bikerboy cb600 some of this is correct, he is just missing a few points
You are correct. Just got very confused as to how you explained it.
Centripetal force..... Sniiiiffff.... Shocks..... Sniiiiffff.... Dude lay off the blow
Lol
that's not centripetal force,no centrifugal no centripetal.
I really appreciate the video bro but it was confusing af haha. Maybe a video with the go pro on a first person view doing the actual lean would be helpful
Ruthless Bone Damn! I was hoping that I made it simple to understand. Thanks for the feedback!
Take a basic high school physics class. This is wrong.
u really just make this video, really seem out of your comfort zone with this video.... taking on corners is easier for you haha
RidingwithSam English please.
lol I need to check on sentences I type in the future...... I cannot understand it as well
dude, that is not how physics work
noise cancelling bro! too much background noise

Not workin’....but nice try. Your intention is great....
Not at all a technical explanation..better teach practically !!
Hey its me random dude who knows nothing about bike but got curious how the leaning thingy you see in images works, at 3 am ...
