rear brake use

jrshooter · January 19th, 2017, 07:16 AM

excuse me, we have a month and a half before i ride again, lots a time to think.
i was listening to kh podcast on rear brake use, ken said you can drag the rear brake to suck the front in and tighten your line.
so my wonderment is, turn 1 at thill , the turn speed is a few mph less than what i can achieve comming down the front straight. 99 for the straight 93 plus for turn 1, can i leave it pinned drag a little rear brake for turn in? the way i am doing it is to roll off at turn in, but it seams to over slow me.
thanks.

Good question. Been around Thunderhill many times, but never on a 250/300. Have always had to brake significantly into turn 1, whether on a 600 or 1K, with the highest speeds on the entire track hit right before that braking point. That said, my hunch would be that the fastest 250/300's are rolling around turn 1 pinned. It's a 100 mph turn that's banked properly with a wide exit.

while your there alex. comming up the hill to turn 8 is another wide open turn
i was told keep it pinned slide up on the tank get your head way out in front. curios if this applys to turn 1, the pod cast got me thinking is all.

I have used rear brake to stabilize the bike numerous times in all kinds of circumstances whether its street or track.

Definitely. One thing I never thought about before Aaron Stevenson at Cornerspin brought it up was that using the rear brake affects the bike in a completely different way than rolling off or using the front brake. By rolling off or using the front, we're changing the drive chain load, which acts on the swingarm, and front fork compression.

Not that I'm anywhere near fast enough to use the rear.

Kevin Schwantz has said he doesn't use the rear brake on track as it distracts from his front brake and reference points.

Use the rear to suck the front in to tighten your line? Thats what trailbraking the front does.The forks compress,causing the rake to "shorten"and makes the front turn in quicker.Using the rear to tighten your line is from getting the rear to slip just enough to drift the rear around to tighten it up.Bare in mind everyone rides different and has different theories on things.Some people make certain theories work and others cannot make the same things work for themselves.What ive explained is what works for me.
