    But how does it actually work? Why should we do it? And Is it really as effective as you think it is?

      Yeah, this is what I was thinking. 4 degrees less of lean angle means you have four more degrees of lean that you can get, meaning you can go some amount faster and still lean as much. His tests largely held speed constant to judge the lean angle differential, which is why his lap times weren't affected.
      Lean angle has no impact on speed, but it does have impact on how much speed you choose to use.

      Yup, whenever i take corners not using lean out techniques, my bike feels like shooting outside the corner. But whenever lean out is applied i take the same corner with faster approach without any doubts. And that 4degree means world of difference in a GP bike shooting out 250HP.

      Most of us will never reach the maximum lean angle of a bike, and so I'd argue that not wasting energy moving your body is more useful than keep your bike more upright. But, if you learned to ride by hanging off, or if pretending you're in motogp makes you feel great, there's no escaping the mental side.

    What about the "sail effect" of hanging off which increases wind resistance on the inside of the turn and facilitates the turn? I think that alone explains why you were faster on long sweepers hanging off. Long sweepers are high-speed turns and increasing wind resistance on the inside of the the bike by itself will turn the bike and allow less lean angle and more confidence to go faster.

    • @Ledfndr

    I've found at the moderate lean angles I manage on the street, that when leaning off I have a lot more control over adjusting the lean angle mid corner. If the front or rear starts to slip, I've found that I can drop my weight down and lift the bike up to grip back up. I've also noticed at the same speed I tend to have far less lean angle than some people I ride with by not sitting straight up and down on the bike.
    This video makes me want to try and get some data and see how much the feeling of reduced lean angle is in my head 😅. Its amazing how much reality and perception can differ with things like riding! Great video!

    Well as an 32 years old and a 2003 R6 rider for 7 years now, i got to say that your body going out of the bike is really important, I'm almost always using batlax tires and they wore off very quickly but the grip is awesome, the thing is when your tires are wearing off you feel the rear dancing and the more you lean the motorcycle, more dangerous it is and I try to lean my body more and the bike less so that i won't go to the ground and up until today, i never went, i got some close calls and learn to lean my body more without the bike and it works wonders... All this in the city were the roads are bad and you have traffic and lights, not on track were you go full speed without worrying with other vehicles, and I'm not a reckless driver, sure i did over speed limits sometimes but when there's no traffic and plenty of space to do it. Anyway, if you're talking about safety and not speed, yeah leaning is very important to me, i feel more safe to maneuver my bike and faster if something happens in the city by adjusting my body more and less the bike just because my body would interfere less and toke more time in some situations than the bike and i can alter the direction with the bike smoother while my body is still changing positions. In my honest opinion, just drive the way you feel more comfort because it's not only the race or speed, the feeling of riding a bike is something i can't feel on anything else and that's the most important thing to me. Please be safe and enjoy your corners fellow riders. Sorry for bad inglish, love from Portugal 👊😎

    Great series on motorcycle riding dynamics. I believe racing would provide the clearest canvas for bike dynamics, and I don't race. Riding on the street, I've found that remaining neutral increases my safety factor, I'm able to course correct or slow rapidly in a more controlled (comfortable as you mentioned) manner. Where I ride, I'm always going around blind turns, so I utilize the neutral position most of the time. Now and then, an open curve at speed presents itself and I'm more than happy to lean to the inside and forward. Thank you for your insights.

    Lean angle is interesting and great work Mike. However, lean angle is only relevant for cornering speed if the ultimate tyre grip is affected, so what is the relationship between wheel angle and tyre grip (cornering force)? Perhaps the cornering force is more for +4 degrees from around 40 degrees (larger contact patch)? Perhaps race tyres are designed to give bigger contact patch at high lean angles compared to say a touring tyre where a larger patch is desirable with bike upright, for load capacity and good tyre life? So many questions!!!

    • @marcelotabajara
      @marcelotabajara 2 роки тому +1

      Even if race tyres have an increased contact patch at high lean angles, it just minimizes the fact that you can't open the throuttle too much at maximum lean angle. When racing superbikes you want to accelerate as soon as possible exiting the corners, and it happens at the moment when you leave the maximum lean angle. Ultimately, and racing is all about extract any little bit of performance from wherever you can, hanging off will help you to get this moment a little bit sooner.

    Something to think about is the stability a bike gets when hanging of (half butt) and still maintain most of the pressure through the outside leg and footpeg. Cornering always creates movement in a bike, but when stable you can let the bike do its thing and concentrate on the lines. Compare it with a trailer with the COG before or after the axle.

    Hej Mike!
    I did the same thing to counteract the argument against chicken strips.
    Bike: Tracer 900 / Fj09
    With a new tire, I took a fast route while hanging off measuring the chicken strips left behind.
    Then I took the same route without hanging off. Times pretty much the same.
    Indeed the 2nd time, there were no chicken strips and even though the difference was less than 1cm, I felt a lot more confident hanging off without having to worry about scraping pegs, etc. At the same time, in short low-speed mountainish corners I saw that I was faster while not hanging off thus, I try not to.

  • @rvn920
    @rvn920 2 роки тому

    I really enjoyed the video. The one take way that I wanted you to note in your next ponderings is that while the number of degrees stays fairly small most tires contact patches aren't spherical they tend to be ovular. This means even a slight decrease in lean angle can net a large increase in contact patch meaning that depending on the tire setup and bike geom it could have a vastly different level of effect. I think for the SuperMoto you did great but I feel like it's the bike that would have the absolute least amount of change in performance when compared to moto gp. I was always taught that basically the moment you are both on a bike and a road that requires hanging off to take corners effectively is the moment you need to slow down and hit the track. So I would love to see more information and research into how various tire setups can effect this equation as well.

      In motogp, guys go fast and can use A LOT their body because the TRACK IS VIRTUALY PERFECT.
      BUT in a road racing, you just CANT DO IT, you need to keep a classical riding style cause a normal road has a lot of bumps and different grip levels along its way, sometimes along one corner path.
      SO with your body BEING LESS OUTSIDE THE BIKE, its is FASTER and SAFER to recover from any abnormality.
      IF you do the motogp body positioning style in road race, you will NOT HAVE TIME TO RESET your body position and SAVE the failure.
      So, its safer to ride in a less extreme positioning when youre in a road.

    You know something that would make a really interesting video: what is the ideal body size and weight for a rider in terms of performance. With modern bikes having almost unlimited power, I feel like weight is less of a detriment than it once was. On the contrary, a taller, heavier person (not fat, but just larger build) could potentially require less lean to maximize grip in a complex series of corners, possibly allowing them to maximize them better. It would probably vary on a track by track basis, but it's something interesting to think about compared to cars or karts where almost universally lighter and smaller=faster.

      BUT Pedrosa was ALWAYS the guy who reach the highest lean angle in the paddock. GUESS WHY?
      ALSO, heavier guys could put more temperature in the tires while Pedrosa couldnt (again, development issues help this phenomenon) and because of it, they had less wheelspin outside the corners.
      I bet that Pedrosa would be unbeatable in 600 or 300 cc.

    You say that leaning off only helps a small amount of degrees. But every degree matters because every degree matters for the amount of tyre on the tarmac. You see it with beginning track riders. Often very slow not using their body and have having high lean with really slow laptimes. Also entering corners to slow because the brake to hard. Release the brake to early and unload the front suspension and front tyre and ruin the corner speed. I really liked the comparison with supermoto between legg out and body out. Very interesting.

      @Don8789 4 роки тому

      @@DiscoFang It depends on the shape and wear of the tyre. The tyre is not perfectly round and tapers off to the side. And yes indeed when comparing lean angles one can argue that at some lean angles the difference is almost zero. One could even say that a very worn tyre on the track that as gotten a more triangle like shape has better grip on a very specific lean angle. In general you can say that more lean on the bike means less tarmac on the road, even tho under some angles the difference is pretty much zero.

    I remember back in the 80's, when I began riding, there wasn't much hanging off, but more knee out, as it was used as an air brake to rotate one around the corner better and slow down, with the inferior brakes and tires back then. Actually at the police mc courses today here in Denmark, the instructors don't recommend hanging off as there's to little to gain with modern tires, it's only advised to lean head in to corner and look out of the curve, but than again it's for fast driving on public roads and not extreme racing, where split second counts, where there are no obstructions to crash into.

    The quality of the surface and the Power of the bike are also factors. If you have to correct the lean angle due to loss of Grip and/or loss of traction a more upright seating Position helps you to respond to that(offroad). The onroad explanation seems to be more hanging off.

    Love these videos, altough I am not a track rider. But riding dynamics is interesting any way when presented this way. Could the additional lean angle be explored static? How far can you lean the frame out to the left while you move your body out right and keep the combined cg at the center line of the tyres. An assistent would be needed to catch the bike when over the limit. The additional lean angle could then be measured from video footage from rear tyre lean angle.

    Thank you Mike for your interesting video. I have also often wondered what the difference is between 'hanging out' and 'foot out' . I have the impression that the differences in technique lead me to drive a different line through the bend. Namely, I tend to turn in the corner at a later moment when hanging out than at foot out. May I ask if you recognize this?

    I think it actually gets a bit more complicated. Some turns reward a later sharper initial turn and getting on the throttle earlier, while some turns won't reward much with a fast exit, so gaining time is done on the brakes and trail braking into the turn more. Hanging off can impact how quickly you can get a turn initiated by already being in position. While hanging off, you're also often letting your own body act as a portion of the suspension, and can allow the bike to better react to bumps in mid corner. Also, I've had times where I was hanging off, knee on the ground, and started losing either the front or back. Because my arms and legs could let the bike move, I was able to correct my inputs and save it. If I was sitting neutral on the seat, the bike would've thrown me enough that I wouldn't be able to react or would be causing unintentional inputs.
    That said, on a supermoto, I agree with using the mix of styles, and using whatever works for each corner. I think the most fun I've ever had going into a turn was coming out of a glancing right hand turn in top gear, throttle pinned, and then braking so hard going into a sharp left that I was sticking my left leg out as far as I could just to have weight out to the side to help pull the bike over while I was only making contact with the front tire. Granted, that's also how I got experience lowsiding by braking too far into the corner, and also how I subsequently started learning how to counter a front end slide mid turn.

    • @MikeonBikes
      @MikeonBikes  4 роки тому +1

      My data does not support the claim that hanging off impacts how quickly you can get a turn initiated. In fact, looking at the data, in the turns where I hang off, my lean angle variation over time is slower both on turn in and on exit.
      How does your body act as a portion of the suspension when hanging off?
      When standing up on a dirt bike, your legs become “part of the suspension”. But when hanging off, you are not standing on the pegs with the rest of your body disconnected from the bike.
      To get a stable body position most racers push their outside knee into the tank. This is also why tanks on sport bikes are formed in the way that they are.

    • @chipmunkshavenuts
      @chipmunkshavenuts 4 роки тому +1

      @@MikeonBikes That's interesting with the data. No implications there. I haven't analyzed data for that, just figuring that since the bike wants to fall into the corner when leaning off, it would be easier. Guess that's why data acquisition is beneficial. Maybe I'm just tall, or tend to lean off too much, but even when I have my outer leg locked against the tank, I am supporting a lot of my weight on my legs. When I've had the rear tire step out, my legs just extended as the bike pushed away from me.

      @@chipmunkshavenuts it definitely feels like bikes fall into a corners faster when pre-hanging, but dont forget, when we do that pre-hanging we have to apply steering angle to keep moving in the intended line, letting go of this opposite steering torque is what makes that reaction to fall feel so fast.

    The other thing it does is place your entire body weight at the centre of the bike because of how you hang off using your leg. I think this improves the weight distribution between the front and back & therefore increases net grip & the suspension response to road imperfections.

    🤔 Has the contact area of ​​the tires been taken into account for the different inclination angles? I drive the Michelin Pilot Power 2CT.More inclination means more contact area. There are data sheets from the manufacturer. The fact is, on the gsxr Hangout feels right. Successful description on your part👍

    • @MikeonBikes
      @MikeonBikes  4 роки тому +2

      Indeed tires have many different profiles. I was not able to figure out a way to account for the tires profile in my equations for the torque around the CoG.
      One could speculate that race tires have an optimum contact patch, located at some given lean angle.

  • @jenpsakiscousin4589

  • @motoshoot404
    @motoshoot404 3 роки тому +1

    My only thought is that hanging off might help you to ride 'looser' on the road (not racetrack), reducing the de-stabilising effect of mid-corner bumps. Agree it is probably more a confidence technique rather than physics - maybe a bit of both 😄

    Kevin Schwantz had a much different style that you could see was different from any others on the track. He leaned over but his upper body was move towards the bike's CG. His lower body & knees exactly the same as the others leaning. You notice his upper body always hugging the gas tank keeping the CG over the bike more. I would love to see you test his style like you did here. He was able to slide into corners then control it from bucking him off out of the corner all before computers & traction control on 500cc 2 stroke with a on off switch throttle. Don't think many modern day riders could pull it off.

  • @adams4048
    @adams4048 Рік тому

    In my experience, the big thing is if you're leaned over, set up for the turn and it's sharper/ entering too fast. You have room and you're in position to deal with it, you likely can correct and won't run wide. If you hit a bump or something the bike is much more stable. This is more on roads, but it makes huge difference in those situations. Slow speed, counter lean is your friend. Most commuting type stuff, neutral is best.

  • @veers0r

    It would be interesting how the software you used arrived at the lean angle as determining it using a gyro on a motorcycle is not entirely trivial. Some software derives it using atan(lateral acceleration in g) (which assumes the bike+rider form a disc). It's also what I do in my little go pro lap timer (for now). Anyways, nice to see a bit of moto content during this time.

    • @MikeonBikes

    I feel more confident in corners leaning off the bike too. I wonder if it’s mostly a psychological and physiological thing because you’re positioning your body in the way you want to go, so it feels more like that’s what will happen - like you’re relying more on your body and less on the machine under you.

    • @owencoopersfx

    if you close your eyes and try to walk you gonna use your hands as hitting prevention mechanism automatically, so your knee becomes a sensor for you to not to go down.
