Car vs. bike conrnering speeds

When downforce is added into the equation, there's no comparison. I'd be
surprised if a F3 car isn't quicker round a track than a WSB bike. Haven't
got time to google right now unfortunately.

Yeah but... There is catagorically more grip on a good car that exploits
downforce than there can be on a bike. I'm sure any car that uses said
downforce (like my friend's Evo VIII) could outcorner even the most meanly
ridden GSXR1k.

 

The last comparison I saw of this type was on one of Clarkson's

Saw that program the other night...

It was apparently a bog-standard R1 ridden by Mackenzie (1999-ish
judging from the age of the program itself) and a then-current 911
Carrera 4 (4WD, but not a turbo) driven by a touring car driver, which
Clarkson claimed would have been slower than an RWD 911 in the dry
conditions.

The Porsche just won in the end. They should have been comparing the
bike with a 9 grand car though !

 

Does that really ahve an appreciable amount of downforce? Just
curious, like

They do corner well. Mine feels like the front is straying out in
corners though, er, understeer init?

Must try and work out whether it's the bike or a teddy.

 

What tyres have you got on it?

^^^^^
Nope, I can't work this out at all. WTF?

 

Teddy bear brake lever syndrome.
ie he gives it a squeeze every time he gets scared / goes round a corner.

Nigel Eaton is the cause....

BT010 front and rear.

Whether the cornering behaviour is down to the bike or it's my teddy,
ie I'm scared of leaning after being off bikes for a year and I'm
making it run wide.

 

Ta.

 

Hmm, well I'm on the OEM 011/012 combo, but I've never noticed it.

<after explanations up there^>

If you were squeezing the brake in the corner, you'd more notice this
as the bike sitting up, although this would then cause you to run
wide, I suppose. But it would feel quite different from what I'd
normally think of as understeer.

Hmm, could be, I suppose. Try conciously countersteering, rather than
thinking about leaning over. Just push the inside bar forward a bit
through the bend and see if it helps.

 

I'm wondering if that's what it is. Maybe the profile of the 011
front is different from the 010. I know the 011 is OEM spec on mine
as well.

No, I'm not braking. Well, I am braking IYSWIM but only because I
need to, not out of habit. I could have a "leaning over" teddy.

Yeah, I normally do. Probably just out of practice. Also the tyre
have only done a couple of hundred miles so it could be that the sides
of the front tyre aren't worn in enough to give full grip yet.

 

Oooh snap.

and snap again.

co-incidence perhaps?

 

Do the old counter steering thing. Push on the bars YKIMS. I must admit
the ZXR turns better than the GSXR did. Probably one of the reasons I
like it so much...

No it isn't. but the sidewalls so siffer. Stiffer on the 011 apparently.
This could be it...

Mr, you have an incredably quick bike. You are probably going into bends
far faster than you think. Do the old slow down a bit and build back up
again slowly. Also make sure your haven't picked up target fixation from
being off bikes for so long. Like look at the end of the bend not 20 ft
in front of you.

It sounds like a typical "where's it all my skill gone" after a lapse of
riding. Start of slow and build up again. It will only take a few weeks.
Do a track day or something...

I never did like the 010 combination that much. Not as good feeling as
the 56's. Stick some Pirelli corsa / metzler things on it for a while...

I dunno, if you start with a 9 grand car then you're talking middle-of-the
road small saloon, and you should compare it with a GS500E, or a Fader,
sorry, Fazer, or summat.

you can't compare on price, you can however compare on simialr type, sports
car with sports bike etc.


hmmmm. what's the cage equivalent of a Harley Electraglide Ultra Classic?
and no, yer not allowed to say "a Harley Electraglide Ultra Classic".

 

I was finding a while back that when I went into corners hard, it would
feel as if the front wheel was going to slip out from under me. I was
using countersteering.

I realised that what was happening was that as the lean angle became
greater, by inside arm[1] was straightening. When I consciously relaced
that arm the whole business became a lot smoother and the bike feels
much more planted in the bends, even on greater lean angles.

This may be similar, if his 'teddy' is not leaning.


[1] the one on the inside of the corner: not a physiological disorder.

Possibly, but I don't feel like I am.

Actually fast bends aren't a problem. It's slow stuff like
roundabouts I'm having problems with.

Yeah, I'm pretty sure that's it. 8 months off and then back on to a
faster bike and only going out when it's sunny. Recipe for disaster
really

Not on my bike.

I've always got on superb with 010's on the SV and then the 750.
Assumed they'd be ok on this as well. Might go for the 011/012 combo
next. Had 012's on the 750 for a bit and didn't like them but they
may suit the Thou better.

 

Of course not. It's a hairdresser's car.
For downforce you need a real wing up in the airstream.

 

Or the flat bottom of the car really close to the road.
