In 18 stone+ of static Geordie. I stay leant over and the bike rises. Effectively, I'm "pushing" the bike vertical by hinging at my waist.

Lets change the lean angle to vertical. I'm steering in the way a motorcrosser does. Butt goes to the side, bike pivots. I'm just doing it from leant over back to vertical.

Bear in mind my pressure on the footpeg AND the Knee AND the countersteer are working as one here and I'm not replacing bar countersteer. I'm suplementing it so I dont use *as much* bar countersteer.

I use this exact method as an anti highside technique coming out of the hairpin and railway corner at East fortune and also coming onto the straight at Croft. I also use it at cadwell. Slow corner where you need to get on the power quickly. Bike goes up before body...

I'm giving up on this! I've just wasted 15 quids worth of Dongle time searching youtube for a suitable clip :)

I'm glad the laws of physics no longer apply to your bike :shock: Should help the racing :D

I can understand why you wish to stand the bike upright earlier on exit, and why hanging off to the inside of the corner facilitates that, but you are not a 'static' body in this context.

Now how I would do it is at the point of passing the apex and wanting the bike to rise, I'd unweight my butt off the seat, use *slight* pressure on the bars, my outer foot would push on the outer peg and my kneed would come up to the tank. As I push with my foot and my knee, my BODY stays still and the BIKE rises. (in effect I hang off a lot more) I am in the same position as the corner. The bike comes up *followed* by the body.
It allows the bike to get back up and onto the fatter part of the tyre sooner and without lots of bar counter steering over the ripples.

Yeah I can see that. But back to my point about it being all to do with the mass transfer and nothing to do with the weight on the pegs.

And back to the tankslapper stuff too, skipping off little ripples won't cause a slapper, I get that all the time, it's different to a slapper... which can happen on level road with the slightest excitation. An inherent instability in the bike creating that sort of damaging feedback function which causes the shake.

Fair enough on some POS bike with flexy frame you need to be very careful... but SV frame is not prone to it.

Good stuff.

Thats what you get for having bridgestone's on!!!! i have ever only found then ****e with no feel or feedback!!

I have BT023's front and back on my ZX6 and had no problems at all, I know at least 4 peiople that have them and no issues either no slipping even when banked right over, must be something to do with the bike or rear tyre.

Although did feel **** while running in, but now they are awesome.

Re: New Bridgestone BT023, now poor handling.

might be silly question but can you u get a steering damper on a 650? i know they come with the 1000.

Re: New Bridgestone BT023, now poor handling.

Yes you can fit aftermeerkat ones or from another bike... but they just mask any problem, better to cure the problem.

Re: New Bridgestone BT023, now poor handling.

Well bugger me backwards! I did know what I was talking about.

I was just calling it the wrong thing. Pressure on the outside peg is called Pivot point. So there you go, thats what I do.

start reading at page 68 (if you can be bothered)

Pivot steering starts with the the opposite foolpeg (sic), moves through the torso and down to the bar
