Motorcycle Trail Braking Explained

Why You Need to Be Trail Braking
.
Came across this vid as I watched the little Honda Grom vid.
.
This technique is explained quite well.
Also, he suggests Nick Ienatsch's book, Sport Riding Techniques (Amazon)
.

Thanks.

Although it's about motorbikes, it's also consistent with what Vic Elford says in his 911 Performance Handbook.

That is generally how I ride. However I have noticed that the front brake makes my bike feel like it's standing up which is contrary to a compressed front fork. I've been thinking that it feels that way because my steering input hasn't taken into account the change in trail due to braking.


The video shows a locked rear brake when mentioning rear brake trailing. That is certainly true enough but I've found that if you properly trail the rear (w/out locking) you can settle the suspension without upsetting the front...much. I could be wrong and totally willing to be corrected.

To learn this technique I had to unlearn the bad habit of braking hard then coasting into the apex, then hard on the throttle.
It was frustrating.
Even now, I have to always remind myself to have a couple fingers on the front lever while street riding. And not for cornering, but for safety.

~~~~~~~~~~
Front braking into a corner turns your front wheel inward...causing the bike to want to stand up.

I've never driven a 2 wheeled vehicle that I didn't have to pedal. I'm pretty sure that if I did, I'd like it, a lot, and while I do have a strong sense of self preservation, I don't trust myself. Besides, the drivers in Houston are the worst that I've ever seen, and I've driven all over the place (we'll assume that India and Russia are in their own class and don't really count for comparison's sake. I haven't driven either place, but I've seen the videos).

I've seen a bunch of the clips online of the sport bike racers that are trail braking into a corner and then powering out of the corner and seem to be drifting the bike at least through the braking, and sometimes a little coming out of the corner too. It's beautiful when done like that and I'm not really a bike guy, but man, it's just poetry in motion. I wish I could have found a good video with a bunch of clips to post into this thread.

I used to ride 40 hrs a week where I had to do tight U-turns and turn around in small spaces. If not enough steering lock to make the turn, sometimes a quick dab of the front brake increased fork angle enough to make the turn. Chopper guys wouldn't understand.

Understanding motorcycle front suspension:

OFFSET: Centerline of the top steering neck to the centerline of the top of the fork tubes.
RAKE: The angle in degrees of the steering neck from vertical.
FORK LENGTH: The distance between the top of the fork tubes to the centerline of the axle.
DIAMETER: The diameter of the front tire.
TRAIL: The distance defined by the vertical line from axle to ground and the intersection of centerline of the steering neck and ground.
RAKED TRIPLE TREES: In order to bring trail figures back into line, triple trees with raked steering stems can be used. Usually adjustable in 3, 5, 7 degrees of rake.

Steve,
Of course the pro riders grew up on dirt.
The riders on the local tracks who grew up on the dirt would slide into corners.
I never dirt rode, so I was always nervous when sliding.
That, and I didn't want to see $20,000 sliding across the asphalt.

It has to do with the geometry of the bike. Some bikes are neutral on the brakes in a corner and others aren't.

My BMW R1100S, with telelever, stays pretty true while trail braking.
