Which is exactly what I tried - and failed, it would seem - to point out in my previous post. No one is expecting that you'd use a super-advanced skill with any control medium before learning the basics. However, using the rear brake is a basic skill. I wouldn't expect anyone to use the throttle to drift the rear tyre on their first track day. It's a much more advanced skill that comes with experience. I don't expect anyone to use the rear brake to stabilise their suspension geometry on their first day. It's an advanced skill that comes with experience.
To my mind, not expecting someone to have the essentials of the use of the rear brake is like expecting them not to have reasonable ability in use of the throttle.
I so not think you failed to make your point, I guess that like you, I have a different perspective. I will include it in greater detail below.
I guess we'll agree to disagree. Using the rear brake is a basic skill. It is not an advanced skill. MotoGP riders don't make it all the way to MotoGP before they start using their rear brakes. No, they used it all the way from the peewee bikes they started on. I think people should be forced to ride a dirt bike off road for a couple of years before getting a license to ride on the street. Learning the basics on the street or racetrack is much more dangerous. But that's just me. Also, not all riders choose to use the rear and can do quite well, but it's a choice that works best for that particular individual. It will always be wrong to tell someone to not learn how to use it, even early on. You're cheating them. Now, certainly if I see someone using all or mostly rear in most/all situations I will educate them that most of the braking power comes from the front and to help them work on that, but I won't tell them to stop use the rear completely.
I think we need to be absolutely clear that we are discussing track riding here, exclusively. Or at least that was my understanding? If not then yes, I completely agree with you that everyone should know how to use the rear brake on a motorcycle, and more appropriately when
to use it.
For track riding, it really is quite simple. As I briefly explained before, the front brake is responsible for the vast majority of your stopping power. >90% for sure and I hope that we can all agree on this fact.
The reason I strongly advise against messing with the rear brake on the track is simple ROI. Unless a rider is fully utilizing the front brake, that is where they should be focusing their efforts. Considering that most track riders never master this skill, to me it seems senseless to invest energies elsewhere.
The only way to increase speed on the track (which should be the goal of every track rider) is to maximize use of their controls. When feeding throttle on after a turn, it should be the goal of the rider to add as much throttle as possible without crashing. I add throttle until my rear just starts to spin and then I know that I am accelerating as fast as I can. Can we agree on this?
The same is true of braking. If you are touching your brake lever at all, you should be braking as hard as the conditions allow. Meaning that if you are going into a turn and using 20% of your braking ability when the grip is available for 80% (which is your average track rider) you are leaving time on the table.
Let's use a scenario of straight up and down braking because it allows for easy math. Rider A is entering a braking zone and using 20% of their brakes to go from 100mph to 30mph in 400', Rider B is entering the same zone and uses 80% of their braking and slows from 100mph to 30mph in 150'. That is 250' that Rider B can be on the throttle while Rider A is already slowing down and so Rider B would have significantly faster lap times. Sorry for the back story but it is necessary to ensure that everyone understands that front brake mastery directly=faster lap times. Using this example it is very easy to see that mastering this skill is paramount.
Now, to the subject at hand. Rider B is braking at 80% which is enough to make his rear wheel light or start to 'dance' on the pavement. What happens if he is also using the rear brake? The rear wheel locks up solid, that's what. The rear tire/wheel constitutes about 60% of the rotational mass of the motorcycle (crankshaft and front wheel making up the remainder). The gyroscopic effect of that rotating mass is what gives the bike its stability so if you manage to lock up the rear wheel you have just reduced the stability of the motorcycle by 60%.
Now, even if the rider is absolutely capable of successfully utilizing the rear brake on the track, it is good for maybe
.5 a lap. The return on learning that skill is so small, I would always recommend that a rider invest their time into other areas that will yield better results.
I do appreciate your viewpoint and if the above tirade does not at least shed some light into my thinking then as you said we will have to agree to disagree. I do love that we can actually have an intelligent debate on this forum without it turning into a shit show =)
you guys. Can we all kum ba yah around a fire now? =)
