Hi lads, maybe a silly question here. When you watch BSB or anything similar, you see them steaming into heavy braking sending the arse out and sort of steering it into the next corner. Is that the case that its a benefit or just because they're riding on the edge?

Usually because they're pushing grip levels to their limits, but on occasion, I do believe its been known by some racers to actually use a "Point and Squirt" technique, where they try and parallel the bike with the next straight very quickly and open up as fast as possible....



whether this has any merit or not, I have no idea.

Imagine extremely heavy braking at the front of the bike. It unloads the rear end, making it very light and liable to move. I would imagine this could be controlled with rear brake usage, but as we know the rear brake is not as effective as not all racers use it much.

I suspect a lot of it is just 'tart factor'. However, as mentioned, it can actually be useful to mean you can get on the power that fraction of a second earlier than your rival.

Definitely a case of "don't try this at home" Smile.

If you want tart factor then look no further than Garry McCoy!

I assume once the rears gone light its just body position to move it sort of thing?
Defo f**k trying it though just looks smart lol.

Backing it in is done by dumping it down a gear too many.
I wouldn't be surprised if they 'tuned' slipper clutches to help them doing.
If you dump it down a gear too many, normally the engine speed will fairly quickly catch up with the road speed. To keep it sliding, you then use the rear brake to keep the engine/rear wheel speed the same amount below the road speed.
Takes some /serious/ skill to then get on the power and link the backing-it-in slide to the power-slide!

was at bsb on monday and someone I know was helping someone in the MAP raceways team in the 600 superstock he was having problems with the rear sliding on the corner entry as the slipper clutch was giving too much engine braking into the corners which they were trying to avoid.
so I agree it is banging down on the gears on corner entry. you dont have to be superhuman to do it, a bit of confidence on a trackday will get the same affect.

I'm not sure he's technically 'backing it in', seeing that he seems to straighten up before actually turning properly. Not bad skills, though.

To get a decent controlled sustained slide while at race pace around a corner takes a lot of skill I reckon - a lot more than having it slide out from engine braking then come back into line. I've done the latter, but am a long way away from the former Sad.

I would have said that was more jumping on the rear brake.

The back tends to skid around a wee bit, just because there's so little weight on it at maximum braking, especially when you get ham fisted with the clutch and start just popping it out.

you can do it on the road, its pretty easy in a straight line, however takes a bit more skill to push it out sideways.

brake fairly hard while going down the gearbox (not too much, you dont want chatter) with a dab of rear brake (A DAB!) and it should get squirming.

I have had it happen a few times to me, never on purpose round a bend mind. I do it all the time in a straight line, I seem to love smashing down the gears Laughing
