Tyres and grip?

[carty]

Right, I've been to the edges of my rear tyre (just) on both sides. I know this was done on the left side by a certain bend that I like, which I was going round at about 65mph. The bike felt completely stable at this speed and when I got off I'd been to the edge. Before that time there was a little chuck strip.

Now my question is, in theory, in the same conditions, could I go round that same bend at 70mph or 80mph? Or would I be 'riding off the edge' of the rear?

There's no right or wrong answer; and I won't press charges for your opinions if you tell me I could go faster and it doesn't work :eye:, I just wondered if people can give me opinions based on experience and / or maths!

Cheers,
Matt

Yes probably much faster, lean off the bike more, unless you were already and this certain bend is like a hairpin :cool: hard to tell without riding it.being there.

+1. lean off the bike more and you can go faster... would I advise doing this? No. :D

Noted, I should have said that the knee was already down - it's not a hairpin by any means but it's reasonably tight - I think there's a sign that recommends 30 or 40 round it - but we know those can be taken with a pinch of salt!

I think a lot of it might come down to the line you take through it, too, w.r.t. speed you can get through it at.

Yeah, you can prolly go faster!! 8) the best way to tell is when you end up in a bush, you have exceeded the limit at that point, so go a little bit slower than that next time - sorted!!!! 8)

Without seeing the corner, the tyre, or how you are riding, it is impossible to give any more useful information that that ;)

You can go this fast:)

F### me that was a bite and a half :-P

I reckon that you don't really like the falco, and you're just trying to justify the fact that you spent too much money on a TL-wannabe that you don't really like...


Anyway, grip...

More about how much power you're putting down that absolute lean angle, blueSV650 has a cool photo of his tyre after a race, there's still a tiny chicken strip despite the tyre being well cooked.

Crikey, this thread drifted pretty far overnight! :offtopic:

Greek, I'm 100% positive, definitely sure that G was yanking your chain about the Falco - we all know they're pretty damn capable machines - now kiss and make up! :smt052


Cart how far off the edge are you on the front?

Not too far actually, about 5-10mm on the left. The front tyre's pretty much vertical if you're right on the edge so I don't want to get there! :smt009

Footpegs weren't scraping though come to think of it, so I must still have some room for leaning further :confused: Must try harder!

[carty]

I often wonder that???

I'm pretty much on the edge front and rear on one side, yet I hang my toes off the edge of the peg so that my toe will touch down way before the peg, yet it never has.

I'm beginning to think I would loose the front or back way before the pegs touch down.

I guess as someone said above that it would depend how fast / hard you're going because if you're going relatively slow for the arc of the corner, you could lean all the way over nice and gently, but if you're really going for it and your suspension is compressed then your pegs will be closer to the floor - possibly quite substantially.

Anyone with more knowledge / experience confirm?

Yes the faster you go the more G's you pull and the more your suspension compresses meaning that your floor clearance decreases. If you get your pegs down on a newer Gixxer its because its on its side. These are practically race bikes, ground clearance should be more than enough. ;)

[carty]

Anyone...possibly...maybe...got any comments about the topic? :smt020






Just jesting fellas :lol:. More opinions welcome though!

Guess you missed this cat. Sorry for being off topic... It seems to just keep happening :(

In my honest opinion you are leaning enough and you dont want to push it any further or you may just regret it. Just try to enjoy the experience. If you really want to know what your bike can do then get to the track. ;)

[carty]

No I got that post mate cheers - I agree that the pegs are pretty high on the gixxer - they have hero blobs on though so Suzuki must be expecting them to scrape at times!

Just wondered if anyone had any other ideas :)

Don't worry I'm not all out worried about getting that extra 1 degree, I'm just trying to understand my margin for safety / error. And believe me, I'm not on the edges all the time, far from it! It's just one particular corner that I'm comfortable with that I know I go to the edge.

Cheers,
Matt

[ThEGr33k]

Ahhh right. Well I think getting on the power helps pull the bike over... Id does mine anyway settles it and lets me lean more. Ive visited the edge of my tires enough to pretty much remove the writing thats on the edge. I dont go out looking to get to the edge it just happens.

I suppose the faster you go the more you lean... But that's not 100% true.

Cartwrim:

Lean angle as well as throttle control dictate the amount of the rear tyre you have used. The more lean you have the less additional load the tyre can cope with so to go fast you generally want to be leaning as little as possible. But that's not to say that because a tyre's worn to the edge that there's no more grip there. The key is to be smooth, make sure you roll the throttle in through the corner and that you feel for rear grip. The ideal place for doing this is a track day because you get to do the same corner every mile or so and take it a little quicker each time without any other road users or Armco;)

I generally don't use the whole of my front tyre even on track, braking into the corner would almost certainly get rid of the remaining strips but I don't have the stones for that:rolleyes:

Be careful, you can always come out of a corner thinking "could have taken that a bit quicker" but when you're over the limit it can be painful and expensive:joker:
