What would happen first under hard breaking?

[Jerry421a]

I am curious what would happen under extreme breaking. Lets assume clean dry pavement and a
2014 ish V7 all factory including Pirelli sport demon tires.

All three are possible. It depends on the skill of the rider. The first possibility is the worst and it usually results in complete loss of control and gravity winning, and you losing.

When I took my motorcycle safety course we practiced a lot of hard braking and unexpected braking Find a parking lot and practice so you have the feel and idea of what will happen and how you and your bike will react.

break
brāk/
verb
gerund or present participle: breaking

1. separate or cause to separate into pieces as a result of a blow, shock, or strain."the rope broke with a loud snap"

brake
brāk/
verb
gerund or present participle: braking

1. make a moving vehicle slow down or stop by using a brake.
   "she braked at the traffic lights"

Now that is out of the way...
Far too theoretical of a post. As John says, rider ability comes into play here. Inexperienced riders will likely get the first one ending in a crash. With a stock brake setup on a V7, the second is very highly unlikely, if not nearly impossible. The last selection is the result with most experienced riders.
Find a nice clean and clear paved lot and slowly practice for yourself; It is a skill needed to get your license, and it's a drill given during my track day owner/instructor days.

I can tell you what will happen if I'm wearing my new, still very slippery, leather riding pants. My crotch will slide forward onto the fuel tank and maybe come to rest on the steering pivot. Ouch!

Another possibility - I've had it happen on other bikes:
Rear wheel lockup and skid.

As mentioned, such an open question. You did not say if you were talking about the front brake, the back brake, or both. And, as mentioned rider ability comes into play. Without ABS it is easily possible to simply apply the front brake too fast and lock the front tire. That can be done without actually applying too much front brake, just by applying it too fast. When applying the front brake you need the weight of the bike to transfer to the front tire as part of the process. If you apply full front brakes before the weight can transfer to the front the front tire can lock up.
If you apply full front brakes in a proper controlled manner the rear tire will likely come up off the ground. If you apply the front brake properly on good pavement the bike will stand up on the front tire until it loops over, an endo. But it only takes a minor pavement issue, a difference in grip, to alter the balance which can result in the front tire locking up. But if there is no grip issue and the front brake is applied properly, the front tire will not lock. In that case the bike will flip if you apply the front brake hard enough. Full brakes on a V7 without ABS would mean the rear tire is just off the ground. With ABS you may not be able to get quite as much braking power. But you would be less likely to lock the front brake if you came up short on grip or technique.

The V7ii is the first bike I've owned with ABS. I'm familiar with ABS in my car but how does it work on a bike? Can I just grab a hand/footful of brake and trust the wonders of modern tech, tyres and road surfacing to bring me up to a halt?

 

[DK-V7classic]

Use your engine!(gear decell) Helped me countless times. In co-op with both brakes. If u only use your rear brake, u Will skid and dive. If you use all those, you can controll your rear wheel skid.
The harder u pull your front brake, the more weight there will be on the front, you want an Even slight distribution, but always the majority on the front.

With slippry gravel, sandy road... Count your prayers, you will want to avoid using the front brake. Gear decell priority. But its ekstremely tricky.

In all cases, look for alternative paths, to avoid collision.

And the same for wet weather..

 

[roadscum]

It depends of the rider skills. The range of possibilities extend from swift controlled stop to a major catastrophic event ending in a BIG BNAG, followed by BIG MEDICIAL BILLS, and perhaps a funeral.

I think I know how to brake well when needed having owned bikes over the years without abs. I was just curious as to how far you can push it and does the abs cause that shuddering like it does in a car. I'm guessing it does as long as the tyre can grip.

 

[oldlegs]

Just find a safe place and try it at about 15mph, it's best that you experience it in a safe place when you are expecting it than in an emergency. Steve.

Sure, we all think that.

But can you brake properly? Is it a muscle reflex for ya? Will it happen correctly in an emergency situation? When was the last time you had training/coaching under the council of a skilled and certified instructor? Food for your consideration.

Yes.... I'm a former MSF instructor/coach, stopped teaching 14 years ago when I relocated to Florida. Now, every few years, I enroll in a class just to keep my skills fresh. Shit happens quickly out there and I'm thinking I can never be too skilled.

Last summer I came very close to wacking a deer at high speed while in a curve on the Lolo. Yikes, we were so close I saw the flees jumping off him onto me! It was proper braking in a curve, a reflex action, that saved my arse.

Yep Like many things in life you never stop learning. Over confidence is a killer too. I've been thinking of doing another rider training course. Last one I did was about 25 years ago run by Honda iirc.
