What racing lines do MotoGP riders such as Marquez, Dovizioso, Rins and Rossi use? What is a defensive line? Why would you use a squared off line vs a progressive line? Lets figure it out. #motogp #motorcycleracing
He is doing well and is growing steadily. Life isn't fair anyways. If it was, he would of course have grown even faster for having such high quality content from the start. He was under 10k subs for a disproportionate time, but now over 100k. It seems the growth is somewhat exponential HIs videos are still good and in many ways much better. The motard racing was an immense increase in enjoyment. He is not just talking but doing, and doing well enouhg to be entertaining to watch him do it.
Excellent video as always Mike. In your Line Selection Criteria - #6 Opponent Strengths/Weaknesses, I'm sure that the riders take into account the mentality of their opponents, and try to read what their opponents are likely to do, (and this would vary depending upon what stage the race is at) in any given situation - some riders like the late Marco Simoncelli, Andrea Iannone, and even the younger Marquez and Rossi were known for making late, balls out lunges, forcing the issue, (even employing the "dark arts") while some riders will ride far more conservatively, biding their time, reading their opponents over a couple of laps before committing to a move. This of course comes under strengths/weaknesses, but mentality is slightly different from skill set. Rossi was a master at reading the minds of his opponents - seemingly more aware of what his opponents would do before they knew themselves. This isn't a criticism of your list, just a minor addition, and of course it's only my opinion.
Squaring off also provides awesome advantage on road riding as you win visibility along the corner while entering on a moderated speed. And you're able to exit with better visibility of what comes next and a closer line when accelerating so that you avoid ending up on the opposite lane (Or too near from cars coming in opposite direction). :)
Another awesome insight backed up by science. Couldn’t have said it any better. That’s the difference between an average to good racer, to the best! They have more tools in their boxes. 👍😎
the way I've always startted to figure out the best line is to work my way backwards from the exit in to each corner or corner complex. prioritizing the corner exit speed at the end. The longer the straight the more the exit is the priority. then you have to just keep tweaking and testing the line the bike and the style until it fits the track and conditions.
Editing etc is once again very good and entertaining, but try to get the facts to same level. Squared off line was used in two stroke era. It is not a fast line, but a safe line when power spike kicks in. With modern bikes trail braking is always used. So the actual line before (late) apex is a bezier curve. And line after apex is also a bezier curve. More straightish if apex speed is low and engine power is high. And more roundish if apex speed is high and engine power is low. That is why motogp and moto3 uses different lines on same track. A defensive line is just more straightish before apex, to keep the "door shut".
always watchin motogp'ive tried this many times'sir'fast cornering'on the streets'risky but in a safe time'without traffic'and people'it gives less stress for the bike too'
misano 2019 also a great example. yellow ppl always said marc brake checked fabio. they should ride a bike them self, lean at 50 degree, then hit the brake, preferably the front one, we will see something interesting lol. marc prepared this for a whole race basically. studied every last bit which line fabio will take in that corner. then marc just closed the inside line. he also said if this plan failed he had another trick inside his sleeves in the next corner.
I had an argument with a friend about racing lines because I play racing games with cars and he recently started playing Ride 4, he had a video where he went really wide on a corner I said that he would've been faster if he hugged the inside, the only argument he made was that "it's a motorcycle" so after some words on the search bar I found my answer, I understand what he meant to do but he overshot his intended line
I think this video could be better. The examples are not very good although most of the reasoning is good. The typical “braking as late as possible” line is more of an early diagonal to the inside of the turn than a late turn-in. In fact in almost all of the examples I think it is important to highlight what effect braking has. Also worth mentioning that simply the shortest distance possible is sometimes the quickest way around a curve. Going out wide in the middle of a long corner might allow a faster exit with a second apex, but at the cost of travelling a much greater distance, though you did touch on this in the the “what comes after?” part. There is much more to be said about all of this stuff.
2:25 "turning in quick." I understand the yellow line is exaggerated. It will be a smaller radius than the blue line. But in either case, wouldn't the rider need to lean the bike in quickly? The blue line is a constant radius, correct? In order to start following that circular line as close to the outside line as possible, he has transition from straight line to this circular arc as quickly as possible, no? Doesn't that mean the rider taking the blue line (at higher speed) has to lean the bike in just as quickly and deeply as the one making the yellow line (at lower speed)? If the rider leaned the bike more slowly, wouldn't he have to start turning earlier? Wouldn't the bike would drift away from the outside line earlier, so the final, tightest radius circular arc would have to be smaller? Seems to me that if a racer is going to take this sort of line where he leans in slower, he is probably going to be braking a bit more as he starts to lean and trailing that brake off closer to the point he reaches the tightest part. Versus the classic "largest radius possible out-in-out" line.
The racer would be braking later and trailing deeper to maximize his use of the bike's traction circle whenever he's not leaning in quick. He's got 100 points, and the racer is going to try to use up to 99 of them as much as he can, so long as he has world class skill and is OK with crashing now and then. He'd be flirting closer to the edge of traction for longer, so that he can make this lazy, spiral line a bit faster. And if he flirts close enough to the edge of his traction circle for long enough, braking as near as hard as possible throughout the entire corner entry and making a smooth transition to maintenance throttle on time, this line can sometimes be slightly faster in times than the classic out-in-out line. Otherwise, the classic wide as possible circular line can be taken at the same or slightly higher apex/carry speeds, and there's no further need to prod the limits once you're reached your line. Just hold a steady speed, lean angle, and arc from here til the exit starts. You've already made it, once you've reached your line/lean. The video mentions a higher risk with this approach due to greater time spent leaned deeply. But one you've learned the track, you'd know which corners have bumps and bank angle changes and what lines you're trying to make. As the video mentioned, Jorge and many other successful racers favor these kinds of classic wide-circle lines, and you could say they do ok. But with the advent of traction control, some of the top racers are pushing the limits of trail braking more frequently, especially on the wider tracks where slow spiral lines will have a bit of reward if you are willing to risk it. With TC evening the playing field, the margins are smaller. You have to take on more risk, more often, to gain a slight advantage over the rest of the field. In a racing sense, trail braking is not safer. It's the expert/pro approach. It's taking on more risk and more workload for sometimes slightly better lap times, or better blocking/passing.
squaring the angle looks like a very "unfair" tehnic. i am a total rookie btw: but still i ve driven enough vehicules to tell that it makes the dude behind braking.
It's perfectly possibly to have a square racetrack - it just wouldn't be a good racetrack, and depending on how wide the track is the racing line could actually be a circle.
Mike's content is fantastic, but he seems to be working on the assumption that his viewers have a good grasp of physics. He also drops in a lot of equations without fully explaining what each variable is, and what it does. This certain isn't a criticism as it's difficult to assess the understanding your subscribers - dumbing down wouldn't do the channel any favours, but he could possibly spend a a small amount of time explaining the equations.
There is no such thing as centrifugal force. Think about it F=ma and the acceleration is in the direction of the force. this is the opposite of your diagram. The force that changes your direction is towards the inside of the curve or you would not turn, it is called centripetal force and the illusion of the outward force is your inertia.
