backing it in

[murf]

Sounds a little easier to initiate on a supermoto? Looks like one has to use alot more rear brake on a SS especially with a slipper clutch?

Some of you guys are trying to explain something you don't understand yourselves?

Do you point at airplanes and say "That's a car?"

those were corner exit slides initiated by throttle application.

Backing it in is not the same and is done for different reasons.

For those interested in trying, read this

The same principals apply to roadrace bikes, however, roadrace suspension carries and stores MUCH more energy because of the extra weight the bikes have.

When you put a bike sideways, the rear shock will compress, this stores energy in the spring, which is going to be released at some point.

A properly configured roadrace setup will normally have a relatively quick rebound circuit to keep the rear tire on the ground.

This quick release of the stored energy in the spring is what causes the corner entry highside when you back it in and don't get it right.

Rich, you get one on one instruction at our next trackday.

If you highside, I'll laugh and drive your wife home when you go to the hospital

you use NO rear brake at all to initiate the slide.

the rear brake is used to decrease the arc of the turn as you slide, dragging the rear slightly will tighten up the slide.

for this to work, the rear wheel MUST remain spinning, the arc of the turn in slide can be controlled by increasing or decreasing the speed the rear wheel spins at. the gearbox/slipper clutch act at a constant rate, the clutch slips X amount under X load based on the weight of the reaction spring in the slipper unit, using the rear brake allows you to modulate the rear wheel speed.

Thing of it as a backwards throttle.

With throttle, the more you apply, the more the tire wants to accelerate and spin, causing the bikes line to widen.

with the rear brake, the more that is applied, the slower the rear wheel spins and the line of the bike tightens up.

Clear as mud?


Rich, I'm not Canada's best anything

Dony Condour?????

[rishkid]

you don't know who these people are they are top Canadian motorcycle experts in there own right/field

Dony Condour?????

He's laughing at your terrible spelling.

Its OK, you're pretty, you don't need to be smart.

[doozerdave]

This has been a good week so far. We have somebody who wants to back it in and another guy that wants to drag his elbow. haha...

[fsilva_mcl]

does anyone here other than reciprocity knows how to properly and safely back a motorcycle in to the corners at a trackday

please explain in full detail how to do it and what you are doing on the bike from begining to end including body position?

A couple of books I've got try and explain how it's done, I haven't gotten that far yet so I haven't tried. When I get home I'll get the names of the books for you. But Recip's explanation above is almost exactly what the book says. Ever drift a rear wheel drive car? The principle seems the same.

However they do stress that the best way to learn how to back it in is not on the track and not with your pretty zx10r. If you want to try it on the track I hear those Racer5 bikes may be able to do this and thus it might be a safer/cost effective starting point.

[reciprocity]

its NOTHING like drifting in a car.

drifting in a car is done with the application of power and controlled wheelspin.

This is NOT the same as backing it in.

Through spending time on this website and going to TMP on 24 weekend I was able to figure out that I saw you on the TV on Saturday morning!

I've me a few people, but i aint never met no Dony Condour.

Where?

[SweetOnion]

Where?

It was on TSN 2, a track in Quebec... on the phone at work, let me check on the name... 1 sec

maybe round 2 parts can superbike

I was only at Mosport this year... was it race footage?

The Quebec race was on first, then it showed Mosport I guess.

yes it was, I think you were running in 4th at the time?? Not sure, by looking at the results now I'm starting to think I'm way off.

They did the highlights of Icar, then showed the Race City race.

I don't remember seeing any silly Newfies on tv.

They have only broadcast the Mirabel and Calgary Rounds... wasn't me

Stay tuned next week though

This is a hilarious thread.
From many of the trackdays that I have seen recently most of you have trouble going forwards let alone backwards....... I say we get a "Backing it In" trackday organized I will bring the popcorn.

And i will bring a trailer and cash to buy parts.
